1. Field

The present invention relates to compounds, prodrugs, and methods of using these compounds and prodrugs thereof in the treatment of conditions in which modulation or inhibition of Protein Kinase C (also known as PKC) is therapeutically useful. This invention also relates to pharmaceutical compositions comprising these compounds, methods of using these compounds in the treatment of various diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.

2. Background

Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within cells (see, e.g., Hardie and Hanks, The Protein Kinase Facts Book , I and II, Academic Press, San Diego, Calif., 1995). Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.). Sequence motifs have been identified that generally correspond to each of these families (see, e.g., Hanks & Hunter, (1995), FASEB J. 9:576-596; Knighton et al., (1991), Science 253:407-414; Hiles et al., (1992), Cell 70:419-429; Kunz et al., (1993), Cell 73:585-596; Garcia-Bustos et al., (1994), EMBO J. 13:2352-2361).

The Protein Kinase C family is a group of serine/threonine kinases including at least twelve related isoenzymes, including alpha, beta 1, beta 2, gamma, delta, epsilon, nu, lambda, mu, theta and zeta. When activated, the isozymes bind to membrane phospholipids or to membrane receptors and anchor the enzymes in a subcellular compartment (reviewed in Liu and Heckman, Cell. Signal, 1998, 10, 529-542). Protein Kinase C isozymes differ in number and expression level in different cell lines and tissues. The isoenzymes have been divided into three groups based on their differential expression patterns and cofactor requirements. The classical PKC enzymes (cPKC), including alpha, betel, beta 2 and gamma isozymes, require diacylglycerol (DAG), phosphatidylserine (PS) and calcium for activation. The novel PKC's (nPKC), including delta, epsilon, theta and eta isozymes, require DAG and PS but are calcium independent. The atypical PKC's (aPKC), including zeta, lambda/iota do not require calcium or DAG.

Protein kinase C's in general are commonly known to be related to cell proliferation, differentiation, metabolism, and apoptosis, and to have many roles in the radiation-induced cellular responses involving apoptosis. However, PKC-theta is primarily implicated in T cell activation and regulation of immune responses and in insulin resistance in skeletal muscle. PKC-epsilon and a related kinase, PKC-mu (or PKD1) are implicated in a variety of activities including sensitisation of the transient receptor potential vanilloid 4 (TRPV4), a neural ion channel involved in PAR-mediated pain.

In view of the numerous conditions that may benefit by treatment involving modulation of PKC it is immediately apparent that new compounds that modulate PKC and methods of using these compounds should provide substantial therapeutic benefits to a wide variety of patients. Provided herein are novel 2,4-pyrimidinediamine compounds for use in the treatment of conditions in which inhibition of PKC, is therapeutically useful.

B. Definitions

As used herein, the following definitions shall apply unless otherwise indicated.

“Alkyl” refers to monovalent saturated aliphatic hydrocarbyl groups having from 1 to 10 carbon atoms and preferably 1 to 6 carbon atoms. This term includes, by way of example, linear and branched hydrocarbyl groups such as methyl (CH 3 —), ethyl (CH 3 CH 2 —), n-propyl (CH 3 CH 2 CH 2 —), isopropyl ((CH 3 ) 2 CH—), n-butyl (CH 3 CH 2 CH 2 CH 2 —), isobutyl ((CH 3 ) 2 CHCH 2 —), sec-butyl ((CH 3 )(CH 3 CH 2 )CH—), t-butyl ((CH 3 ) 3 C—), n-pentyl (CH 3 CH 2 CH 2 CH 2 CH 2 —), and neopentyl ((CH 3 ) 3 CCH 2 —). Also by way of example, a methyl group, an ethyl group, an n-propyl and an isopropyl group are all represented by the term C 1-3 alkyl. Likewise terms indicating larger numerical ranges of carbon atoms are representative of any linear or branched hydrocarbyl falling within the numerical range. This inclusiveness applies to other hydrocarbyl terms bearing such numerical ranges.

“Alkylene” refers to divalent saturated aliphatic hydrocarbyl groups preferably having from 1 to 6 and more preferably 1 to 3 carbon atoms that are either straight-chained or branched. This term is exemplified by groups such as methylene (—CH 2 —), ethylene (—CH 2 CH 2 —), n-propylene (—CH 2 CH 2 CH 2 —), iso-propylene (—CH 2 CH(CH 3 )—) or (—CH(CH 3 )CH 2 —), and the like.

“Substituted alkylene” refers to an alkylene group having from 1 to 3 hydrogens replaced with substituents as described for carbons in the definition of “substituted” below.

“Alkoxy” refers to the group —O-alkyl, wherein alkyl is as defined herein. Alkoxy includes, by way of example, methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, t-butoxy, sec-butoxy, n-pentoxy, and the like.

In a preferred embodiment, a group that is substituted has 1, 2, 3, or 4 substituents, 1, 2, or 3 substituents, 1 or 2 substituents, or 1 substituent.

It is understood that in all substituted groups defined above, polymers arrived at by defining substituents with further substituents to themselves (e.g., substituted aryl having a substituted aryl group as a substituent which is itself substituted with a substituted aryl group, which is further substituted by a substituted aryl group, etc.) are not intended for inclusion herein. In such cases, the maximum number of such substitutions is three. For example, serial substitutions of substituted aryl groups are limited to substituted aryl-(substituted aryl)-substituted aryl.

“Stereoisomer” and “stereoisomers” refer to compounds that have same atomic connectivity but different atomic arrangement in space. Stereoisomers include cis-trans isomers, E and Z isomers, enantiomers, and diastereomers.

“Tautomer” refers to alternate forms of a molecule that differ only in electronic bonding of atoms and/or in the position of a proton, such as enol-keto and imine-enamine tautomers, or the tautomeric forms of heteroaryl groups containing a —N═C(H)—NH— ring atom arrangement, such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles. A person of ordinary skill in the art would recognize that other tautomeric ring atom arrangements are possible.

“Patient” refers to human and non-human animals, especially mammals.

“Pharmaceutically acceptable salt” refers to pharmaceutically acceptable salts of a compound, which salts are derived from a variety of organic and inorganic counter ions well known in the art and include, by way of example only, sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium, and the like; and when the molecule contains a basic functionality, salts of organic or inorganic acids, such as hydrochloride, hydrobromide, tartrate, mesylate, acetate, maleate, oxalate, and the like.

“Prodrug” refers to a derivative of an active 4-pyrimidineamine compound (drug) that may require a transformation under the conditions of use, such as within the body, to release the active 2,4-pyrimidinediamine drug. Prodrugs are frequently, but not necessarily, pharmacologically inactive until converted into the active drug. Prodrugs are typically obtained by masking one or more functional groups in an active 2,4-pyrimidinediamine drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active 2,4-pyrimidinediamine drug. The cleavage of the promoiety may proceed spontaneously, such as by way of a hydrolysis reaction, or it can be catalyzed or induced by another agent, such as an enzyme, light, an acid or base, or a change of or exposure to a physical or environmental parameter, such as temperature. The agent can be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it can be supplied exogenously.

“Progroup” refers to a type of protecting group that, when used to mask a functional group within an active 2,4-pyrimidinediamine drug to form a promoiety, converts the drug into a prodrug. Progroups are typically attached to the functional group of the drug via bonds that are cleavable under specified conditions of use. Thus, a progroup is that portion of a promoiety that cleaves to release the functional group under the specified conditions of use. As a specific example, an amide promoiety of the formula —NH—C(O)CH3 comprises the progroup —C(O)CH3.

“Pharmaceutically effective amount” and “therapeutically effective amount” refer to an amount of a compound sufficient to treat a specified disorder or disease or one or more of its symptoms and/or to prevent the occurrence of the disease or disorder. In reference to tumorigenic proliferative disorders, a pharmaceutically or therapeutically effective amount comprises an amount sufficient to, among other things, cause the tumor to shrink or decrease the growth rate of the tumor.

“Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water.

Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “arylalkyloxycarbonyl” refers to the group (aryl)-(alkyl)-O—C(O)—.

Similarly, it is understood that the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluoro groups). Such impermissible substitution patterns are easily recognized by a person having ordinary skill in the art.

Those of skill in the art will appreciate that the 2,4-pyrimidinediamine compounds described herein may include functional groups that can be masked with progroups to create prodrugs. Such prodrugs are usually, but need not be, pharmacologically inactive until converted into their active drug form. Indeed, many of the 2,4-pyrimidinediamine compounds described in this invention include promoieties that are hydrolyzable or otherwise cleavable under conditions of use. For example, ester groups commonly undergo acid-catalyzed hydrolysis to yield the parent carboxylic acid when exposed to the acidic conditions of the stomach, or base-catalyzed hydrolysis when exposed to the basic conditions of the intestine or blood. Thus, when administered to a subject orally, 2,4-pyrimidinediamine compounds that include ester moieties can be considered prodrugs of their corresponding carboxylic acid, regardless of whether the ester form is pharmacologically active.

The mechanism by which the progroup(s) metabolizes is not critical, and can be caused by, for example, hydrolysis under the acidic conditions of the stomach, as described above, and/or by enzymes present in the digestive tract and/or tissues or organs of the body. Indeed, the progroup(s) can be selected to metabolize at a particular site within the body. For example, many esters are cleaved under the acidic conditions found in the stomach. Prodrugs designed to cleave chemically in the stomach to the active 2,4-substituted pyrimidinediamine, can employ progroups including such esters. Alternatively, the progroups can be designed to metabolize in the presence of enzymes such as esterases, amidases, lipolases, phosphatases including ATPases and kinase etc. Progroups including linkages capable of metabolizing in vivo are well known, and include, by way of example and not limitation, ethers, thioethers, silylethers, silylthioethers, esters, thioesters, carbonates, thiocarbonates, carbamates, thiocarbamates, ureas, thioureas, carboxamides, etc. In some instances, a “precursor” group that is oxidized by oxidative enzymes such as, for example, cytochrome P450 of the liver, to a metabolizable group, can be selected.

In the prodrugs, any available functional moiety can be masked with a progroup to yield a prodrug. Functional groups within the 2,4-pyrimidinediamine compounds that can be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), carboxyls, etc. A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in active 2,4-pyrimidinediamine compounds to yield prodrugs are well-known in the art. For example, a hydroxyl functional group can be masked as a sulfonate, ester or carbonate promoiety, which can be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group can be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl or sulfenyl promoiety, which can be hydrolyzed in vivo to provide the amino group. A carboxyl group can be masked as an ester (including silyl esters and thioesters), amide or hydrazide promoiety, which can be hydrolyzed in vivo to provide the carboxyl group. Other specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art. All of these progroups, alone or in combinations, can be included in the prodrugs.

In some embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the progroup(s) can be attached to any available primary or secondary amine, including, for example, the N2 nitrogen atom of the 2,4 pyrimidinediamine moiety, the N4 nitrogen atom of the 2,4 pyrimidinediamine moiety, and/or a primary or secondary nitrogen atom included in a substituent on the 2,4 pyrimidinediamine compound.

In particular embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the prodrugs described herein are 2,4-pyrimidinediamine compounds that are substituted at the N4 nitrogen of the 2,4 pyrimidinediamine moiety with a substituted or unsubstituted nitrogen containing bicyclic ring that includes at least one progroup at one or more of: the nitrogen atom(s) of the bicyclic ring, the N2 nitrogen of the 2,4 pyrimidinediamine moiety and/or the N4 nitrogen of the 2,4 pyrimidinediamine moiety.

As noted above, the identity of the progroup is not critical, provided that it can be metabolized under the desired conditions of use, for example under the acidic conditions found in the stomach and/or by enzymes found in vivo, to yield a the biologically active group, e.g., the 2,4-substituted pyrimidinediamines as described herein. Thus, skilled artisans will appreciate that the progroup can comprise virtually any known or later discovered hydroxyl, amine or thiol protecting group. Non limiting examples of suitable protecting groups can be found, for example, in Protective Groups in Organic Synthesis , Greene & Wuts, 2nd Ed., John Wiley & Sons, New York, 1991 (especially pages 10-142 (alcohols, 277-308 (thiols) and 309-405 (amines) the disclosure of which is incorporated herein by reference).

Additionally, the identity of the progroup(s) can also be selected so as to impart the prodrug with desirable characteristics. For example, lipophilic groups can be used to decrease water solubility and hydrophilic groups can be used to increase water solubility. In this way, prodrugs specifically tailored for selected modes of administration can be obtained. The progroup can also be designed to impart the prodrug with other properties, such as, for example, improved passive intestinal absorption, improved transport mediated intestinal absorption, protection against fast metabolism (slow release prodrugs), tissue selective delivery, passive enrichment in target tissues, targeting specific transporters, etc. Groups capable of imparting prodrugs with these characteristics are well known, and are described, for example, in Ettmayer et al., 2004 , J. Med. Chem. 47(10):2393-2404, the disclosure of which is incorporated by reference. All of the various groups described in these references can be utilized in the prodrugs described herein.

As noted above, progroup(s) may also be selected to increase the water solubility of the prodrug as compared to the active drug. Thus the progroup(s) may include or can be a group(s) suitable for imparting drug molecules with improved water solubility. Such groups are well known, and include, by way of example and not limitation, hydrophilic groups such as alkyl, aryl, arylalkyl, or heterocyclyl groups substituted with one or more of an amine, alcohol, a carboxylic acid, a phosphorous acid, a sulfoxide, a sugar, an amino acid, a thiol, a polyol, an ether, a thioether, and a quaternary ammonium salt.

The suitability of any particular progroup for a desired mode of administration can be confirmed in biochemical assays. For example, if a prodrug is to be administered by injection into a particular tissue or organ, and the identities of the various enzyme(s) expressed in the tissue or organ are known, the particular prodrug can be tested for metabolism in biochemical assays with the isolated enzyme(s). Alternatively, the particular prodrug can be tested for metabolism to the active 2,4-pyrimidinediamine compound with tissue and/or organ extracts. Using tissue and/or organ extracts can be of particular convenience when the identity(ies) of the enzymes expressed in the target tissues or organs are unknown, or in instances when the isolated enzymes are not conveniently available. Skilled artisans will be able to readily select progroups having metabolic properties (such as kinetics) suitable for particular applications using such in vitro tests. Of course, specific prodrugs could also be tested for suitable metabolism in vitro animal models.

Numerous references teach the use and synthesis of prodrugs, including, for example, Ettmayer et al., ibid and Bungaard et al., (1989) J. Med. Chem. 32(12): 2503-2507. Additionally, the preparation and use of prodrugs of 2,4-pyrimidinediamines is specifically taught in U.S. Provisional Patent Application 60/654,620, filed Feb. 18, 2005, entitled “Pyrimidinediamine Prodrugs and their Uses,” U.S. patent application Ser.

One of ordinary skill in the art will appreciate that many of the compounds and prodrugs thereof, as well as the various compound species specifically described and/or illustrated herein, may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism and/or optical isomerism. For example, the compounds and prodrugs of the invention may include one or more chiral centers and/or double bonds and as a consequence may exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers), enantiomers and diastereomers and mixtures thereof, such as racemic mixtures. As another example, the compounds and prodrugs of the invention may exist in several tautomeric forms, including the enol form, the keto form and mixtures thereof. As the various compound names, formulae and compound drawings within the specification and claims can represent only one of the possible tautomeric, conformational isomeric, optical isomeric or geometric isomeric forms, it should be understood that the invention encompasses any tautomeric, conformational isomeric, optical isomeric and/or geometric isomeric forms of the compounds or prodrugs having one or more of the utilities described herein, as well as mixtures of these various different isomeric forms. In cases of limited rotation around the 2,4-pyrimidinediamine core structure, atropisomers are also possible and are also specifically included in the compounds of the invention.

D. Methods of the Invention

Protein Kinase C theta (also known as PKC-theta, PKCT, PRKCT, nPKC-theta and PRKCQ) is a member of the nPKC sub-family. It has a restricted expression pattern, found predominantly in T cells and skeletal muscle. Upon T cell activation, a supramolecular activation complex (SMAC) forms at the site of contact between the T cell and antigen presenting cell (APC). PKC-theta is the only PKC isoform found to localize at the SMAC (C. Monks et al., Nature, 1997, 385, 83), placing it in proximity with other signaling enzymes that mediate T cell activation processes. In another study (G. Baier-Bitterlich et al., Mol. Cell. Biol., 1996, 16, 842) the role of PKC-theta in the activation of AP-1, a transcription factor important in the activation of the IL-2 gene, was confirmed. In unstimulated T cells, constitutively active PKC-theta stimulated AP-1 activity while in cells with dominant negative PKC-theta, AP-1 activity was not induced upon activation by PMA. Other studies showed that PKC-theta, via activation of I-kappa-B kinase beta, mediates activation of NF-kappa-B induced by T cell receptor/CD28 co-stimulation (N. Coudronniere et al., Proc. Nat. Acad. Sci. U.S.A., 2000, 97, 3394; X. Lin et al., Mol. Cell. Biol., 2000, 20, 2933). Proliferation of peripheral T cells from PKC-theta knockout mice, in response to T cell receptor (TCR)/CD28 stimulation was greatly diminished compared to T cells from wild type mice. In addition, the amount of IL-2 released from the T cells was also greatly reduced (Z. Sun et al., Nature, 2000, 404, 402). Otherwise, the PKC-theta knockout mice seemed normal and were fertile.

PKC-theta, one of the novel serine/threonine Protein Kinase C isoforms (nPKC), is expressed ubiquitously in tissues with the highest levels found in hematopoietic cell lines, including T-cells and thymocytes (Baier et al., J. Biol. Chem., 1993, 268, 4997-5004; Keenan et al., Immunology, 1997, 90, 557-563; Meller et al., Cell. Immunol., 1999, 193, 185-193; Wang et al., Biochem. Biophys. Res. Commun., 1993, 191, 240-246). This isozyme has been shown to be specifically responsible for antigen driven activation events in peripheral T cells. PKC-theta is not required for the development of T cells in the thymus, as PKC-theta knock-out mice develop normal numbers of peripheral T cells. However, when these mice are challenged with an antigen, they fail to make a T cell response.

It has been well established that T cells play an important role in regulating the immune response (Powrie and Coffman, Immunolog Today, 1993, 14, 270). Indeed, activation of T cells is often the initiating event in immunological disorders. Following activation of the T-cell receptor (TCR), there is an influx of calcium that is required for T cell activation. Upon activation, T cells produce cytokines, including IL-2, leading to T cell proliferation, differentiation, and effector function. Clinical studies with inhibitors of IL-2 have shown that interference with T cell activation and proliferation effectively suppresses immune response in vivo (Waldmann, Immunology Today, 1993, 14, 264). Accordingly, agents, such as PKC-theta inhibitors, that dampen T lymphocyte activation and subsequent cytokine production are therapeutically useful for selectively suppressing the immune response in a patient in need of such immunosuppression and therefore are useful in treating immunological disorders such as autoimmune and inflammatory diseases.

In addition, PKC-theta activation has been shown to be associated with insulin resistance in skeletal muscle (M. E. Griffen et al., Diabetes, 1999, 48, 1270). Therefore inhibitors of PKC-theta can also be useful for treating type II diabetes.

The present invention provides 2,4-pyrimidinediamine compounds and prodrugs thereof, as described herein, for use in therapy for the conditions as described herein. The present invention further provides use of the compounds of the present invention in the manufacture of a medicament for the treatment of conditions in which inhibition of PKC-theta can be therapeutically useful. Conditions in which inhibition of PKC-theta can be therapeutically useful include, but are not limited to, asthma, atopic dermatitis, allergic rhinitis, systemic anaphylaxis, hypersensitivity responses, drug allergies, insect sting allergies, dermatitis, eczema, urticaria, inflammatory bowel disease, Crohn's disease, ileitis, Celiac disease, nontropical Sprue, enteritis, enteropathy, colitis, eosinophilic gastroenteritis, ileoanal anastomosis, disorders of the skin, multiple sclerosis, systemic lupus erythermatosus, myasthenia gravis, juvenile onset diabetes, glomerulonephritis, autoimmune thyroiditis, Behcet's disease, graft rejection, stroke, cardiac ischemia, mastitis, vaginitis, cholecystitis, cholangitis, chronic bronchitis, chronic sinusitis, chronic inflammatory diseases of the lung, hypersensitivity pneumonitis, collagen diseases, sarcoidosis, vasculitis, spondyloarthropathies, scleroderma, atherosclerosis, restenosis, myositis pancreatitis, insulin-dependent diabetes mellitus, metabolic syndrome, autoimmune thrombocytopenia, rheumatoid arthritis, osteoarthritis, multiple sclerosis, inflammatory bowel disease, psoriasis, organ transplantation, graft vs. host disease, asthma, and chronic obstructive pulmonary disease and the other conditions described herein. Given the severity of and suffering caused by these conditions, it is vital that new treatments are developed to treat these conditions.

Exacerbated sensitivity to mechanical stimuli that are normally innocuous or mildly painful (mechanical allodynia and hyperalgesia) occurs during inflammation and underlies painful diseases. Proteases that are generated during inflammation and disease cleave protease-activated receptors (PARs), a family of four G-protein-coupled receptors, on afferent nerves to cause mechanical hyperalgesia in the skin and intestine. One mechanism for PAR-mediated hyperalgesia involves sensitization of the ion channel transient receptor potential vanilloidI-4 (TRPVI-4). PAR2-agonist was shown to sensitize TRPV4-dependent Ca2+ signals and currents in primary dorsal root ganglion (DRG) neurons and TRPV4-dependent release of neuropeptides from dorsal horn of rat spinal cord. In addition, intraplantar injection of PAR2 agonist caused mechanical hyperalgesia in mice and sensitized pain responses to the TRPV4 agonists whereas deletion of TRPV4 prevented PAR2 agonist-induced mechanical hyperalgesia and sensitization. Antagonists of phospholipase C-β and protein kinases A, PKC and PKD inhibited PAR2-induced sensitization of TRPV4. This novel mechanism, by which PAR2 activates a series of enzymes including PKCε and PKD1 to sensitize TRPV4-dependent release of nociceptive peptides and induce mechanical hyperalgesia, indicates that inhibitors of PKCε and PKD1 may be useful therapies for a variety of inflammatory and painful conditions.

Protein Kinase C epsilon is one of the novel PKC (nPKC) isozymes which response to DAG but not to calcium. Protein Kinase C-mu (also known as PKD1) encodes a cytosolic serine-threonine kinase that belongs to the Protein kinase D (PKD) family, which is part of the CAMK group of kinases. PKD family is composed of three mammalian homologs (PKD1/PKCmu, PKD2, and PKD3/PKCnu) encoded by distinct genes. PKDs are ubiquitously expressed at varying levels in different tissues. Similar to PKCs, PKDs have two cysteine-rich, DAG/PMA-binding C1 domains at the N-terminus, a central Pleckstrin-homology (PH) domain, and a conserved kinase domain at the C-terminus. Like many kinases, PKD kinase activity is negatively regulated by intramolecular interactions. Various studies have shown that stimulus-dependent binding of lipids (phosphatidylserine and DAG) to C1 domains, protein binding to or tyrosine phosphorylation of the PH domain, and phosphorylation of serine residues in the activation loop of the kinase domain can release the kinase from autoinhibition.

PKD isoforms are effectors of nPKCs in signaling cascades controlled by DAG. DAG regulates the intracellular localization of PKD and also activates PKD through nPKC by phosphorylation. Depending on the cellular context or activating stimulus, all four isoforms in the nPKC family have been shown to directly phosphorylate the activation loop serine residues. Important discoveries have been made regarding the roles of PKDs in regulating cell growth, gene expression, survival, motility, Golgi vesicle fission and trafficking, and lymphocyte biology in response to reactive oxygen species, growth factors, activators of GPCRs, and stimulators of antigen receptor complexes.

As noted previously, numerous conditions can be treated using the 2,4-substituted pyrimidinediamine compounds, prodrugs thereof, and methods of treatment as described herein. As used herein, “Treating” or “treatment” of a disease in a patient refers to (1) preventing the disease from occurring in a patient that is predisposed or does not yet display symptoms of the disease; (2) inhibiting the disease or arresting its development; or (3) ameliorating or causing regression of the disease. As well understood in the art, “treatment” is an approach for obtaining beneficial or desired results, including clinical results. For the purposes of this invention, beneficial or desired results can include one or more, but are not limited to, alleviation or amelioration of one or more symptoms, diminishment of extent of a condition, including a disease, stabilized (i.e., not worsening) state of a condition, including diseases, preventing spread of disease, delay or slowing of condition, including disease, progression, amelioration or palliation of the condition, including disease, state, and remission (whether partial or total), whether detectable or undetectable. Preferred are compounds that are potent and can be administered locally at very low doses, thus minimizing systemic adverse effects.

The compounds described herein are potent and selective inhibitors of PKC. As a consequence of this activity, the compounds can be used in a variety of in vitro, in vivo and ex vivo contexts to inhibit PKC activity.

No. 6,241,969; U.S. Pat. No. 6,060,069; U.S. Pat. No. 6,238,647; U.S. Pat. No. 6,335,316; U.S. Pat. No. 5,364,838; U.S. Pat. No. 5,672,581; WO96/32149; WO95/24183; U.S. Pat. No. 5,654,007; U.S. Pat. No. 5,404,871; U.S. Pat. No. 5,672,581; U.S. Pat. No. 5,743,250; U.S. Pat. No. 5,419,315; U.S. Pat. No. 5,558,085; WO98/33480; U.S. Pat. No. 5,364,833; U.S. Pat. No. 5,320,094; U.S. Pat. No. 5,780,014; U.S. Pat. Nos. 5,658,878; 5,518,998; 5,506,203; U.S. Pat. No. 5,661,130; U.S. Pat. No. 5,655,523; U.S. Pat. No. 5,645,051; U.S. Pat. No. 5,622,166; U.S. Pat. No. 5,577,497; U.S. Pat. No. 5,492,112; U.S. Pat. No. 5,327,883; U.S. Pat. No. 5,277,195; U.S. Pat. Pub. No. 20010041190; U.S. Pat. Pub. No. 20020006901; and U.S. Pat. Pub. No. 20020034477.

Included among the devices which can be used to administer particular examples of the 2,4-pyrimidinediamine compounds are those well-known in the art, such as, metered dose inhalers, liquid nebulizers, dry powder inhalers, sprayers, thermal vaporizers, and the like. Other suitable technology for administration of particular 2,4-pyrimidinediamine compounds includes electrohydrodynamic aerosolizers.

In addition, the inhalation device is preferably practical, in the sense of being easy to use, small enough to carry conveniently, capable of providing multiple doses, and durable. Some specific examples of commercially available inhalation devices are Turbohaler (Astra, Wilmington, Del.), Rotahaler (Glaxo, Research Triangle Park, N.C.), Diskus (Glaxo, Research Triangle Park, N.C.), the Ultravent nebulizer (Mallinckrodt), the Acorn II nebulizer (Marquest Medical Products, Totowa, N.J.) the Ventolin metered dose inhaler (Glaxo, Research Triangle Park, N.C.), or the like. In one embodiment, 2,4-pyrimidinediamine compounds can be delivered by a dry powder inhaler or a sprayer.

As those skilled in the art will recognize, the formulation of 2,4-pyrimidinediamine compounds, the quantity of the formulation delivered, and the duration of administration of a single dose depend on the type of inhalation device employed as well as other factors. For some aerosol delivery systems, such as nebulizers, the frequency of administration and length of time for which the system is activated will depend mainly on the concentration of 2,4-pyrimidinediamine compounds in the aerosol. For example, shorter periods of administration can be used at higher concentrations of 2,4-pyrimidinediamine compounds in the nebulizer solution. Devices such as metered dose inhalers can produce higher aerosol concentrations, and can be operated for shorter periods to deliver the desired amount of 2,4-pyrimidinediamine compounds in some embodiments. Devices such as dry powder inhalers deliver active agent until a given charge of agent is expelled from the device. In this type of inhaler, the amount of 2,4-pyrimidinediamine compounds in a given quantity of the powder determines the dose delivered in a single administration. The formulation of 2,4-pyrimidinediamine is selected to yield the desired particle size in the chosen inhalation device.

Formulations of 2,4-pyrimidinediamine compounds for administration from a dry powder inhaler may typically include a finely divided dry powder containing 2,4-pyrimidinediamine compounds, but the powder can also include a bulking agent, buffer, carrier, excipient, another additive, or the like. Additives can be included in a dry powder formulation of 2,4-pyrimidinediamine compounds, for example, to dilute the powder as required for delivery from the particular powder inhaler, to facilitate processing of the formulation, to provide advantageous powder properties to the formulation, to facilitate dispersion of the powder from the inhalation device, to stabilize to the formulation (e.g., antioxidants or buffers), to provide taste to the formulation, or the like. Typical additives include mono-, di-, and polysaccharides; sugar alcohols and other polyols, such as, for example, lactose, glucose, raffinose, melezitose, lactitol, maltitol, trehalose, sucrose, mannitol, starch, or combinations thereof; surfactants, such as sorbitols, diphosphatidyl choline, or lecithin; or the like.

The present invention also relates to a pharmaceutical composition including 2,4-pyrimidinediamine compounds suitable for administration by inhalation. According to the invention, 2,4-pyrimidinediamine compounds can be used for manufacturing a composition or medicament, including medicaments suitable for administration by inhalation. The invention also relates to methods for manufacturing compositions including 2,4-pyrimidinediamine compounds in a form that is suitable for administration, including administration by inhalation. For example, a dry powder formulation can be manufactured in several ways, using conventional techniques, such as described in any of the publications mentioned above and incorporated expressly herein by reference, and for example, Baker, et al., U.S. Pat. No. 5,700,904, the entire disclosure of which is incorporated expressly herein by reference. Particles in the size range appropriate for maximal deposition in the lower respiratory tract can be made by micronizing, milling, or the like. And a liquid formulation can be manufactured by dissolving the 2,4-pyrimidinediamine compounds in a suitable solvent, such as water, at an appropriate pH, including buffers or other excipients.

Pharmaceutical compositions comprising the 2,4-pyrimidinediamine compounds described herein (or prodrugs thereof) can be manufactured by means of conventional mixing, dissolving, granulating, dragee-making levigating, emulsifying, encapsulating, entrapping or lyophilization processes. The compositions can be formulated in conventional manner using one or more physiologically acceptable carriers, diluents, excipients or auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically.

For ocular administration, the 2,4-pyrimidinediamine compound(s) or prodrug(s) can be formulated as a solution, emulsion, suspension, etc. suitable for administration to the eye. A variety of vehicles suitable for administering compounds to the eye are known in the art. Specific non-limiting examples are described in U.S. Pat. No. 6,261,547; U.S. Pat. No. 6,197,934; U.S. Pat. No. 6,056,950; U.S. Pat. No. 5,800,807; U.S. Pat. No. 5,776,445; U.S. Pat. No. 5,698,219; U.S. Pat. No. 5,521,222; U.S. Pat. No. 5,403,841; U.S. Pat. No. 5,077,033; U.S. Pat. No. 4,882,150; and U.S. Pat. No. 4,738,851.

For prolonged delivery, the 2,4-pyrimidinediamine compound(s) or prodrug(s) can be formulated as a depot preparation for administration by implantation or intramuscular injection. The active ingredient can be formulated with suitable polymeric or hydrophobic materials (e.g., as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, e.g., as a sparingly soluble salt. Alternatively, transdermal delivery systems manufactured as an adhesive disc or patch which slowly releases the active compound(s) for percutaneous absorption can be used. To this end, permeation enhancers can be used to facilitate transdermal penetration of the active compound(s). Suitable transdermal patches are described in for example, U.S. Pat. No. 5,407,713; U.S. Pat. No. 5,352,456; U.S. Pat. No. 5,332,213; U.S. Pat. No. 5,336,168; U.S. Pat. No. 5,290,561; U.S. Pat. No. 5,254,346; U.S. Pat. No. 5,164,189; U.S. Pat. No. 5,163,899; U.S. Pat. No. 5,088,977; U.S. Pat. No. 5,087,240; U.S. Pat. No. 5,008,110; and U.S. Pat. No. 4,921,475.

Alternatively, other pharmaceutical delivery systems can be employed. Liposomes and emulsions are well-known examples of delivery vehicles that can be used to deliver active compound(s) or prodrug(s). Certain organic solvents such as dimethylsulfoxide (DMSO) may also be employed, although usually at the cost of greater toxicity.

The pharmaceutical compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active compound(s). The pack may, for example, comprise metal or plastic foil, such as a blister pack. The pack or dispenser device can be accompanied by instructions for administration.

The 2,4-pyrimidinediamine compound(s) or prodrug(s) described herein, or compositions thereof, will generally be used in an amount effective to achieve the intended result, for example in an amount effective to treat or prevent the particular condition being treated. The compound(s) can be administered therapeutically to achieve therapeutic benefit or prophylactically to achieve prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated and/or eradication or amelioration of one or more of the symptoms associated with the underlying disorder such that the patient reports an improvement in feeling or condition, notwithstanding that the patient may still be afflicted with the underlying disorder. For example, administration of a compound to a patient suffering from an allergy provides therapeutic benefit not only when the underlying allergic response is eradicated or ameliorated, but also when the patient reports a decrease in the severity or duration of the symptoms associated with the allergy following exposure to the allergen. As another example, therapeutic benefit in the context of asthma includes an improvement in respiration following the onset of an asthmatic attack, or a reduction in the frequency or severity of asthmatic episodes. As another specific example, therapeutic benefit in the context of transplantation rejection includes the ability to alleviate an acute rejection episode, such as for example, HVGR or GVHR, or the ability to prolong the time period between onset of acute rejection episodes and/or onset of chronic rejection. Therapeutic benefit also includes halting or slowing the progression of the disease, regardless of whether improvement is realized.

The amount of compound administered will depend upon a variety of factors, including, for example, the particular condition being treated, the mode of administration, the severity of the condition being treated and the age and weight of the patient, the bioavailability of the particular active compound, etc. Determination of an effective dosage is well within the capabilities of those skilled in the art.

As known by those of skill in the art, the preferred dosage of 2,4-pyrimidinediamine compounds will also depend on the age, weight, general health and severity of the condition of the individual being treated. Dosage may also need to be tailored to the sex of the individual and/or where administered by inhalation, the lung capacity of the individual. Dosage may also be tailored to individuals suffering from more than one condition or those individuals who have additional conditions which affect lung capacity and the ability to breathe normally, for example, emphysema, bronchitis, pneumonia, respiratory infections, etc. Dosage, and frequency of administration of the compounds or prodrugs thereof, will also depend on whether the compounds are formulated for treatment of acute episodes of a condition or for the prophylactic treatment of a disorder. For example, acute episodes of allergic conditions, including allergy-related asthma, transplant rejection, etc. A skilled practitioner will be able to determine the optimal dose for a particular individual.

For prophylactic administration, the compound can be administered to a patient at risk of developing one of the previously described conditions. For example, if it is unknown whether a patient is allergic to a particular drug, the compound can be administered prior to administration of the drug to avoid or ameliorate an allergic response to the drug. Alternatively, prophylactic administration can be applied to avoid the onset of symptoms in a patient diagnosed with the underlying disorder. For example, a compound can be administered to an allergy sufferer prior to expected exposure to the allergen. Compounds may also be administered prophylactically to healthy individuals who are repeatedly exposed to agents known to one of the above-described maladies to prevent the onset of the disorder. For example, a compound can be administered to a healthy individual who is repeatedly exposed to an allergen known to induce allergies, such as latex, in an effort to prevent the individual from developing an allergy. Alternatively, a compound can be administered to a patient suffering from asthma prior to partaking in activities which trigger asthma attacks to lessen the severity of, or avoid altogether, an asthmatic episode.

In the context of transplant rejection, the compound can be administered while the patient is not having an acute rejection reaction to avoid the onset of rejection and/or prior to the appearance of clinical indications of chronic rejection. The compound can be administered systemically to the patient as well as administered to the tissue or organ prior to transplanting the tissue or organ in the patient.

The amount of compound administered will depend upon a variety of factors, including, for example, the particular indication being treated, the mode of administration, whether the desired benefit is prophylactic or therapeutic, the severity of the indication being treated and the age and weight of the patient, the bioavailability of the particular active compound, etc. Determination of an effective dosage is well within the capabilities of those skilled in the art.

Effective dosages can be estimated initially from in vitro assays. For example, an initial dosage for use in animals can be formulated to achieve a circulating blood or serum concentration of active compound that is at or above an IC 50 of the particular compound as measured in as in vitro assay. Calculating dosages to achieve such circulating blood or serum concentrations taking into account the bioavailability of the particular compound is well within the capabilities of skilled artisans. For guidance, the reader is referred to Fingl & Woodbury, “ General Principles ,” In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics , Chapter 1, pp. I-46, latest edition, Pergamagon Press, and the references cited therein.

Initial dosages can also be estimated from in vivo data, such as animal models. Animal models useful for testing the efficacy of compounds to treat or prevent the various diseases described above are well-known in the art. Suitable animal models of hypersensitivity or allergic reactions are described in Foster, (1995) Allergy 50(21 Suppl):6-9, discussion 34-38 and Tumas et al., (2001), J. Allergy Clin. Immunol. 107(6):1025-1033. Suitable animal models of allergic rhinitis are described in Szelenyi et al., (2000), Arzneimittelforschung 50(11):1037-42; Kawaguchi et al., (1994), Clin. Exp. Allergy 24(3):238-244 and Sugimoto et al., (2000), Immunopharmacology 48(1):I-7. Suitable animal models of allergic conjunctivitis are described in Carreras et al., (1993), Br. J. Opthalmol. 77(8):509-514; Saiga et al., (1992), Ophthalmic Res. 24(1):45-50; and Kunert et al., (2001), Invest. Opthalmol. Vis. Sci. 42(11):2483-2489. Suitable animal models of systemic mastocytosis are described in O'Keefe et al., (1987), J. Vet. Intern. Med. 1(2):75-80 and Bean-Knudsen et al., (1989), Vet. Pathol. 26(1):90-92. Suitable animal models of hyper IgE syndrome are described in Claman et al., (1990), Clin. Immunol. Immunopathol. 56(1):46-53. Suitable animal models of B-cell lymphoma are described in Hough et al., (1998), Proc. Natl. Acad. Sci. USA 95:13853-13858 and Hakim et al., (1996), J. Immunol. 157(12):5503-5511. Suitable animal models of atopic disorders such as atopic dermatitis, atopic eczema and atopic asthma are described in Chan et al., (2001), J. Invest. Dermatol. 117(4):977-983 and Suto et al., (1999), Int. Arch. Allergy Immunol. 120(Suppl 1):70-75. Suitable animal models of transplant rejection, such as models of HVGR are described in O'Shea et al., (2004), Nature Reviews Drug Discovery 3:555-564; Cetkovic-Curlje & Tibbles, (2004), Current Pharmaceutical Design 10:1767-1784; and Chengelian et al., (2003), Science 302:875-878. Ordinarily skilled artisans can routinely adapt such information to determine dosages suitable for human administration.

Dosage amounts will typically be in the range of from about 0.0001 or 0.001 or 0.01 mg/kg/day to about 100 mg/kg/day, but can be higher or lower, depending upon, among other factors, the activity of the compound, its bioavailability, the mode of administration and various factors discussed above. Dosage amount and interval can be adjusted individually to provide plasma levels of the compound(s) which are sufficient to maintain therapeutic or prophylactic effect. For example, the compounds can be administered once per week, several times per week (e.g., every other day), once per day or multiple times per day, depending upon, among other things, the mode of administration, the specific indication being treated and the judgment of the prescribing physician. In cases of local administration or selective uptake, such as local topical administration, the effective local concentration of active compound(s) may not be related to plasma concentration. Skilled artisans will be able to optimize effective local dosages without undue experimentation.

Preferably, the compound(s) will provide therapeutic or prophylactic benefit without causing substantial toxicity. Toxicity of the compound(s) can be determined using standard pharmaceutical procedures. The dose ratio between toxic and therapeutic (or prophylactic) effect is the therapeutic index. Compounds(s) that exhibit high therapeutic indices are preferred.

The foregoing disclosure pertaining to the dosage requirements for the 2,4-substituted pyrimidinediamine compounds is pertinent to dosages required for prodrugs, with the realization, apparent to the skilled artisan, that the amount of prodrug(s) administered will also depend upon a variety of factors, including, for example, the bioavailability of the particular prodrug(s) the conversation rate and efficiency into active drug compound under the selected route of administration, etc. Determination of an effective dosage of prodrug(s) for a particular use and mode of administration is well within the capabilities of those skilled in the art.

Effective dosages can be estimated initially from in vitro activity and metabolism assays. For example, an initial dosage of prodrug for use in animals can be formulated to achieve a circulating blood or serum concentration of the metabolite active compound that is at or above an IC 50 of the particular compound as measured in as in vitro assay, such as the in vitro CHMC or BMMC and other in vitro assays described in U.S. application Ser.

F. General Synthesis of the Compounds of the Invention

The 2,4-pyrimidinediamine compounds and prodrugs of the invention can be synthesized via a variety of different synthetic routes using commercially available starting materials and/or starting materials prepared by conventional synthetic methods. Suitable exemplary methods that can be routinely adapted to synthesize the 2,4-pyrimidinediamine compounds and prodrugs of the invention are found in U.S. Pat. No. 5,958,935, the disclosure of which is incorporated herein by reference. Specific examples describing the synthesis of numerous 2,4-pyrimidinediamine compounds and prodrugs, as well as intermediates therefore, are described in the U.S. publication No. US2004/0029902A1, the contents of which are incorporated herein by reference. Suitable exemplary methods that can be routinely used and/or adapted to synthesize active 2,4-pyrimidinediamine compounds can also be found in WO 03/063794, U.S. application Ser. No. 10/631,029 filed Jul. 29, 2003, WO2004/014382, U.S. publication No. 2005-0234049 A1, and WO005/016893, the disclosures of which are incorporated herein by reference. All of the compounds described herein (including prodrugs) can be prepared by routine adaptation of these methods.

Exemplary synthetic methods for the 2,4-substituted pyrimidinediamines described herein are described below. Those of skill in the art will also be able to readily adapt these methods for the synthesis of specific 2,4-substituted pyrimidinediamines as described herein.

A variety of exemplary synthetic routes that can be used to synthesize the 2,4-pyrimidinediamine compounds of the invention are described in Schemes I-VII, below. These methods can be routinely adapted to synthesize the 2,4-pyrimidinediamine compounds and prodrugs described herein.

In one exemplary embodiment, the compounds can be synthesized from substituted or unsubstituted uracils as illustrated in Scheme I, below:

In Scheme I, ring A, R 1 , R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as defined herein. According to Scheme I, uracil A-1 is dehalogenated at the 2- and 4-positions using a standard dehydrating-halogenating agent such as POCl3 (or other standard halogenating agent) under standard conditions to yield 2,4 dichloropyrimidine A-2. Depending upon the X substituent, in pyrimidinediamine A-2, the chloride at the C4 position is more reactive towards nucleophiles than the chloride at the C2 position. This differential reactivity can be exploited by first reacting 2,4 dichloropyrimidine A-2 with one equivalent of amine A-3, yielding 4N-substituted-2-chloro-4-pyrimidineamine A-4, followed by amine A-5 to yield a 2,4-pyrimidinediamine derivative A-6, where N4 nitrogen can be selectively alkylated e.g. using an alkylating agent employing a leaving group “LG”, to give compounds of formula I.

Typically, the C4 halide is more reactive towards nucleophiles, as illustrated in Scheme I. However, as will be recognized by skilled artisans, the identity of the X substituent may alter this reactivity. For example, when X is trifluoromethyl, a 50:50 mixture of 4N-substituted-4-pyrimidineamine A-4 and the corresponding 2N-substituted-2-pyrimidineamine is typically obtained. The regioselectivity of the reaction can also be controlled by adjusting the solvent and other synthetic conditions (such as temperature), as is well-known in the art.

The reactions depicted in Scheme I may proceed more quickly when the reaction mixtures are heated via microwave. When heating in this fashion, the following conditions can be used: heat to 175° C. in ethanol for 5-20 min. in a Smith Reactor (Personal Chemistry, Uppsala, Sweden) in a sealed tube (at 20 bar pressure).

The uracil A-1 starting materials can be purchased from commercial sources or prepared using standard techniques of organic chemistry. Commercially available uracils that can be used as starting materials in Scheme I include, by way of example and not limitation, uracil (Aldrich #13,078-8; CAS Registry 66-22-8); 5 bromouracil (Aldrich #85,247-3; CAS Registry 51-20-7; 5 fluorouracil (Aldrich #85,847-1; CAS Registry 51-21-8); 5 iodouracil (Aldrich #85,785-8; CAS Registry 696-07-1); 5 nitrouracil (Aldrich #85,276-7; CAS Registry 611-08-5); 5 (trifluoromethyl)-uracil (Aldrich #22,327-1; CAS Registry 54-20-6). Additional 5-substituted uracils are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

Amines A-3 and A-5 can be purchased from commercial sources or, alternatively, can be synthesized utilizing standard techniques. For example, suitable amines can be synthesized from nitro precursors using standard chemistry. See also Vogel, 1989, Practical Organic Chemistry, Addison Wesley Longman, Ltd. and John Wiley & Sons, Inc. Representative examples of commercially available A-3 amines include, but are not limited to, the structures shown in the following Table V.

Skilled artisans will recognize that in some instances, amines A-3 and A-5 and/or substituent X on uracil A-1 may include functional groups that require protection during synthesis. The exact identity of any protecting group(s) used will depend upon the identity of the functional group being protected, and will be apparent to those of skill in the art. Guidance for selecting appropriate protecting groups, as well as synthetic strategies for their attachment and removal, can be found, for example, in Greene & Wuts, Protective Groups in Organic Synthesis , 3d Edition, John Wiley & Sons, Inc., New York (1999) and the references cited therein (hereinafter “Greene & Wuts”).

Thus, protecting group refers to a group of atoms that, when attached to a reactive functional group in a molecule, mask, reduce or prevent the reactivity of the functional group. Typically, a protecting group can be selectively removed as desired during the course of a synthesis. Examples of protecting groups can be found in Greene and Wuts, as mentioned above, and additionally, in Harrison et al., Compendium of Synthetic Organic Methods, Vols. 1 8, 1971 1996, John Wiley & Sons, NY. Representative amino protecting groups include, but are not limited to, formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (“CBZ”), tert butoxycarbonyl (“Boc”), trimethylsilyl (“TMS”), 2 trimethylsilyl ethanesulfonyl (“TES”), trityl and substituted trityl groups, allyloxycarbonyl, 9 fluorenylmethyloxycarbonyl (“FMOC”), nitro veratryloxycarbonyl (“NVOC”) and the like. Representative hydroxyl protecting groups include, but are not limited to, those where the hydroxyl group is either acylated to form acetate and benzoate esters or alkylated to form benzyl and trityl ethers, as well as alkyl ethers, tetrahydropyranyl ethers, trialkylsilyl ethers (e.g., TMS or TIPPS groups) and allyl ethers.

A specific embodiment of Scheme I utilizing 5-fluorouracil (Aldrich #32,937-1) as a starting material is illustrated in Scheme Ia, below:

In Scheme Ia, ring A, R 1 , R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , and n are as previously defined for Scheme I. Asymmetric 2N,4N-disubstituted-5-fluoro-2,4-pyrimidinediamine A-10 can be obtained by reacting 2,4-dichloro-5-fluoropyrimidine A-8 with one equivalent of amine A-3 (to yield 2-chloro-N4-substituted-5-fluoro-4-pyrimidineamine A-9) followed by one or more equivalents of amine A-5.

In another exemplary embodiment, the 2,4 pyrimidinediamine compounds of the invention can be synthesized from substituted or unsubstituted cytosines as illustrated in Schemes IIa and IIb, below:

In Scheme IIa, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined for Scheme I and PG represents a protecting group. Referring to Scheme IIa, the C4 exocyclic amine of cytosine A-11 is first protected with a suitable protecting group PG to yield N4-protected cytosine A-12. For specific guidance regarding protecting groups useful in this context, see Vorbrüggen and Ruh-Pohlenz, 2001, Handbook of Nucleoside Synthesis, John Wiley & Sons, NY, pp. I-631 (“Vorbrüggen”). Protected cytosine A-12 is halogenated at the C2 position using a standard halogenation reagent under standard conditions to yield 2 chloro 4N protected 4 pyrimidineamine A-13. Reaction with amine A-5 gives A-14, which on deprotection of the C4 exocyclic amine, gives A-15. Reaction of A-15 with amine A-3 yields 2,4 pyrimidinediamine derivative A-6.

In Scheme IIb, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined for Scheme I and PG represents a protecting group. Referring to Scheme IIb, cytosine A-11 can be reacted with amine A-3 or protected amine A-18 to yield N4 substituted cytosine A-16 or A-19, respectively. These substituted cytosines can then be halogenated as previously described, deprotected (in the case of N4 substituted cytosine A-19) and reacted with amine A-5 to yield a 2,4 pyrimidinediamine A-6.

Commercially-available cytosines that can be used as starting materials in Schemes IIa and IIb include, but are not limited to, cytosine (Aldrich #14,201-8; CAS Registry 71-30-7); N4 acetylcytosine (Aldrich #37,791-0; CAS Registry 14631-20-0); 5 fluorocytosine (Aldrich #27,159-4; CAS Registry 2022-85-7); and 5 (trifluoromethyl)-cytosine. Other suitable cytosines useful as starting materials in Schemes IIa are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

In still another exemplary embodiment, the 2,4 pyrimidinediamine compounds of the invention can be synthesized from substituted or unsubstituted 2 amino 4 pyrimidinols as illustrated in Scheme III, below:

In Scheme III, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined for Scheme I and LG is a leaving group as discussed in more detail in connection with Scheme IV, infra. Referring to Scheme III, 2 amino 4 pyrimidinol A-21 is reacted with arylating agent A-22 to yield N2 substituted 4 pyrimidinol A-23, which is then halogenated as previously described to yield N2 substituted 4 halo 2 pyrimidineamine A-24. Further reaction with amine A-3 affords a 2,4 pyrimidinediamine derivative A-6.

Suitable commercially-available 2 amino 4 pyrimidinols A-21 that can be used as starting materials in Scheme III are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

Alternatively, the 2,4-pyrimidinediamine compounds of the invention can be prepared from substituted or unsubstituted 4 amino 2 pyrimidinols as illustrated in Scheme IV, below:

In Scheme IV, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined for Scheme I. Referring to Scheme IV, the C2-hydroxyl of 4 amino 2 pyrimidinol A-25 is more reactive towards nucleophiles than the C4 amino such that reaction with amine A-5 yields N2 substituted 2,4 pyrimidinediamine A-26. Subsequent reaction with compound A-27, which includes a suitable leaving group, or amine A-3 yields a 2,4 pyrimidinediamine derivative A-6. Compound A-27 may include virtually any leaving group that can be displaced by the C4 amino of N2 substituted 2,4 pyrimidinediamine A-26. Suitable leaving groups include, but are not limited to, halogens, methanesulfonyloxy (mesyloxy; “OMs”), trifluoromethanesulfonyloxy (“OTf”) and p-toluenesulfonyloxy (tosyloxy; “OTs”), benzene sulfonyloxy (“besylate”) and m-nitro benzene sulfonyloxy (“nosylate”). Other suitable leaving groups will be apparent to those of skill in the art.

Substituted 4-amino-2-pyrimidinol starting materials can be obtained commercially or synthesized using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

In still another exemplary embodiment, the 2,4 pyrimidinediamine compounds of the invention can be prepared from 2 chloro 4 aminopyrimidines or 2 amino 4 chloropyrimidines as illustrated in Scheme V, below:

In Scheme V, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as defined for Scheme I and leaving group is as defined for Scheme IV. Referring to Scheme V, 2 amino 4 chloropyrimidine A-28 is reacted with amine A-3 to yield 4N substituted 2,4 pyrimidinediamine A-29 which, following reaction with compound A-22 or amine A-5, yields a N2,N4-2,4 pyrimidinediamine derivative A-6. Alternatively, 2 chloro 4 amino-pyrimidine A-30 can be reacted with compound A-27 to give compound A-29 which on reaction with amine A-5 yields A-6.

A variety of pyrimidines A-28 and A-30 suitable for use as starting materials in Scheme V are commercially available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

Alternatively, 4-chloro-2-pyrimidineamines A-28 can be prepared as illustrated in Scheme Va:

In Scheme Va, X is as previously defined for Scheme I. In Scheme Va, dialdehyde A-31 is reacted with guanidine to yield 2-pyrimidineamine A-32. Reaction with a peracid such as m-chloroperbenzoic acid, trifluoroperacetic acid or urea hydrogen peroxide complex yields N-oxide A-33, which is then halogenated to give 4-chloro-2-pyrimidineamine A-28. The corresponding 4-halo-2-pyrimidineamines can be obtained by using suitable halogenation reagents.

In yet another exemplary embodiment, the 2,4 pyrimidinediamine compounds of the invention can be prepared from substituted or unsubstituted uridines as illustrated in Scheme VI, below:

In Scheme VI, ring A, R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined for Scheme I and PG represents a protecting group, as discussed in connection with Scheme IIb. According to Scheme VI, uridine A-34 has a C4 reactive center such that reaction with amine A-3 or protected amine A-19 yields N4 substituted cytidine A-35 or A-36, respectively. Acid-catalyzed deprotection of N4 substituted A-35 or A-36 (when “PG” represents an acid-labile protecting group) yields N4 substituted cytosine A-37, which can be subsequently halogenated at the C2 position and reacted with amine A-5 to yield a 2,4 pyrimidinediamine derivative A-6.

Cytidines may also be used as starting materials in an analogous manner, as illustrated in Scheme VII, below:

In Scheme VII, ring A, R 1 , R 2a , R 2b , R 3 , R 4a , R 4b , (R 5 ) p , n, and X are as previously defined in Scheme I and PG represents a protecting group as discussed above. Referring to Scheme VII, like uridine A-34, cytidine A-38 has a C4 reactive center such that reaction with amine A-3 or protected amine A-19 yields N4 substituted cytidine A-35 or A-36, respectively. These cytidines A-35 and A-36 are then treated as previously described for Scheme VI to yield a 2,4 pyrimidinediamine derivative A-6.

Although Schemes VI and VII are exemplified with ribosylnucleosides, skilled artisans will appreciate that the corresponding 2′ deoxyribo and 2′,3′ dideoxyribo nucleosides, as well as nucleosides including sugars or sugar analogs other than ribose, would also work.

Numerous uridines and cytidines useful as starting materials in Schemes VI and VII are known in the art, and include, by way of example and not limitation, 5 trifluoromethyl-2′ deoxycytidine (Chem. Sources #ABCR F07669; CAS Registry 66,384-66-5); 5 bromouridine (Chem. Sources Int'l 2000; CAS Registry 957-75-5); 5 iodo 2′ deoxyuridine (Aldrich #I-775-6; CAS Registry 54-42-2); 5 fluorouridine (Aldrich #32,937-1; CAS Registry 316-46-1); 5 iodouridine (Aldrich #85,259-7; CAS Registry 1024-99-3); 5 (trifluoromethyl)uridine (Chem. Sources Int'l 2000; CAS Registry 70-00-8); 5 trifluoromethyl 2′ deoxyuridine (Chem. Sources Int'l 2000; CAS Registry 70-00-8). Additional uridines and cytidines that can be used as starting materials in Schemes VI and VII are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

Although many of the synthetic schemes discussed above do not illustrate the use of protecting groups, skilled artisans will recognize that in some instances certain substituents, such as, for example, R 2 and/or R 4 , may include functional groups requiring protection. The exact identity of the protecting group used will depend upon, among other things, the identity of the functional group being protected and the reaction conditions used in the particular synthetic scheme, and will be apparent to those of skill in the art. Guidance for selecting protecting groups, their attachment and removal suitable for a particular application can be found, for example, in Greene & Wuts, supra.

Prodrugs as described herein can be prepared by routine modification of the above-described methods. Alternatively, such prodrugs can be prepared by reacting a suitably protected 2,4-pyrimidinediamine 6 with a suitable progroup. Conditions for carrying out such reactions and for deprotecting the product to yield a prodrugs as described herein are well-known.

Those of skill in the art will appreciate that the 2,4-pyrimidinediamine compounds described herein may include functional groups that can be masked with progroups to create prodrugs. Such prodrugs are usually, but need not be, pharmacologically inactive until converted into their active drug form. Indeed, many of the 2,4-pyrimidinediamine compounds described in this invention include promoieties that are hydrolyzable or otherwise cleavable under conditions of use. For example, ester groups commonly undergo acid-catalyzed hydrolysis to yield the parent carboxylic acid when exposed to the acidic conditions of the stomach, or base-catalyzed hydrolysis when exposed to the basic conditions of the intestine or blood. Thus, when administered to a subject orally, 2,4-pyrimidinediamine compounds that include ester moieties can be considered prodrugs of their corresponding carboxylic acid, regardless of whether the ester form is pharmacologically active.

The mechanism by which the progroup(s) metabolizes is not critical, and can be caused by, for example, hydrolysis under the acidic conditions of the stomach, as described above, and/or by enzymes present in the digestive tract and/or tissues or organs of the body. Indeed, the progroup(s) can be selected to metabolize at a particular site within the body. For example, many esters are cleaved under the acidic conditions found in the stomach. Prodrugs designed to cleave chemically in the stomach to the active 2,4-pyrimidinediamine can employ progroups including such esters. Alternatively, the progroups can be designed to metabolize in the presence of enzymes such as esterases, amidases, lipolases, phosphatases including ATPases and kinase etc. Progroups including linkages capable of metabolizing in vivo are well known, and include, by way of example and not limitation, ethers, thioethers, silylethers, silylthioethers, esters, thioesters, carbonates, thiocarbonates, carbamates, thiocarbamates, ureas, thioureas, carboxamides, etc. In some instances, a “precursor” group that is oxidized by oxidative enzymes such as, for example, cytochrome P450 of the liver, to a metabolizable group, can be selected.

In the prodrugs, any available functional moiety can be masked with a progroup to yield a prodrug. Functional groups within the 2,4-pyrimidinediamine compounds that can be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), carboxyls, etc. Myriad progroups suitable for masking such functional groups to yield promoieties that are cleavable under the desired conditions of use are known in the art. All of these progroups, alone or in combinations, can be included in the prodrugs.

In some embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the progroup(s) can be attached to any available primary or secondary amine, including, for example, the N2 nitrogen atom of the 2,4 pyrimidinediamine moiety, the N4 nitrogen atom of the 2,4 pyrimidinediamine moiety, and/or a primary or secondary nitrogen atom included in a substituent on the 2,4 pyrimidinediamine compound.

In particular embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the prodrugs described herein are 2,4-pyrimidinediamine compounds that are substituted at the N4 nitrogen of the 2,4 pyrimidinediamine moiety with a substituted or unsubstituted nitrogen containing bicyclic ring that includes at least one progroup at one or more of: the nitrogen atom(s) of the bicyclic ring, the N2 nitrogen of the 2,4 pyrimidinediamine moiety and/or the N4 nitrogen of the 2,4 pyrimidinediamine moiety.

As noted above, the identity of the progroup is not critical, provided that it can be metabolized under the desired conditions of use, for example under the acidic conditions found in the stomach and/or by enzymes found in vivo, to yield a the biologically active group, e.g., the 2,4-substituted pyrimidinediamines as described herein. Thus, skilled artisans will appreciate that the progroup can comprise virtually any known or later discovered hydroxyl, amine or thiol protecting group. Non-limiting examples of suitable protecting groups can be found, for example, in Protective Groups in Organic Synthesis, Greene & Wuts, 2nd Ed., John Wiley & Sons, New York, 1991 (especially pages 10-142 (alcohols, 277-308 (thiols) and 309-405 (amines) the disclosure of which is incorporated herein by reference).

Additionally, the identity of the progroup(s) can also be selected so as to impart the prodrug with desirable characteristics. For example, lipophilic groups can be used to decrease water solubility and hydrophilic groups can be used to increase water solubility. In this way, prodrugs specifically tailored for selected modes of administration can be obtained. The progroup can also be designed to impart the prodrug with other properties, such as, for example, improved passive intestinal absorption, improved transport mediated intestinal absorption, protection against fast metabolism (slow release prodrugs), tissue selective delivery, passive enrichment in target tissues, targeting specific transporters, etc. Groups capable of imparting prodrugs with these characteristics are well known, and are described, for example, in Ettmayer et al., 2004, J. Med. Chem. 47(10):2393-2404, the disclosure of which is incorporated by reference. All of the various groups described in these references can be utilized in the prodrugs described herein.

The present invention is not limited in scope by the exemplified embodiments, which are intended as illustrations of single aspects of the invention only. Any methods that are functionally equivalent are within the scope of the invention.
