This application is a U.S. National Phase Application, filed under 35 U.S.C. 371, of International Application No. PCT/US2018/067267, filed on Dec. 21, 2018, which claims the benefit of priority of U.S. Provisional Application No. 62/609,604, filed Dec. 22, 2017, which the entire disclosure of each are incorporated herein by reference in their entirety.
›FIELD OF INVENTION
The present invention is directed to inhibitors of phosphatidylinositol-5-phosphate-4-kinase (PI5P4K) useful in the treatment of diseases or disorders associated with PI5P4K enzymes. In particular, the invention is concerned with compounds and compositions inhibiting PI5P4K, methods of treating diseases or disorders associated with PI5P4K, and methods of synthesis of these compounds.
›BACKGROUND OF THE INVENTION
A minor but ubiquitous component of cells, phosphoinositol lipids are pivotal players in many intracellular signal transduction pathways. Phosphoinositol lipids are formed when phosphatidylinositol (PtdIns) is converted, by the catalytic action of lipid kinases, to polyphosphoinositides. As a prototypic example, the membrane associated phospholipid, phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2), is formed by two successive phosphorylations of PtdIns by the phosphatidylinositol phosphate kinases (PIP kinases).
PtdIns(4,5)P2 is a substrate for phospholipase C (PLC) and is converted into the second messengers inositol-1,4,5-trisphosphate and diacylglycerol (DAG). Phosphoinositides are involved in regulating a broad spectrum of activities from cytoskeletal assembly and motility to vesicle trafficking and exocytosis to transduction of intracellular signals including stimulating the release of intracellular calcium stores (Hinchliffe et al., Biochem. Soc. Trans., 1999, 27, 657-661).
PIP kinases comprise a unique and promiscuous family of enzymes that catalyze the production of poly-phosphorylated inositol lipids from mono-phosphorylated phosphoinositides. Isolation and purification of several different PIP kinase enzymes able to catalyze phosphorylation of phosphatidylinositol 4-phosphate and produce PtdIns(4,5)P2 led to the further categorization of these enzymes, dubbed the phosphatidylinositol 4-phosphate 5-kinases (PIP5Ks), into two types having different activities. The PIP kinases have no homology to other lipid or protein kinases at the primary sequence level, and are distinguished from each other by their lack of immuno-cross reactivity and by the fact that type I PIP5Ks are stimulated in vitro by phosphatidic acid, whereas the type II PIP5Ks are not. Furthermore, the recent discovery that the type II PTP5Ks are able to phosphorylate multiple lipid substrates in vitro suggests that this family of kinases is potentially able to generate several distinct, often subcellularly compartmentalized, phosphoinositol products for regulation of a variety of physiologically important processes (Hinchliffe et al., Biochem. Soc. Trans., 1999, 27, 657-661).
One particular species of PI, phosphatidylinositol 5-phosphate (PI5P), has been implicated in the regulation of the tumor suppressor ING2 and the oncogene AKT. The phosphatidylinositol 5-phosphate 4-kinase (PI5P4K) family (α, β, γ isoforms) catalyzes the conversion of PI5P to P14, 5 P2. These enzymes therefore represent one means by which cells can regulate endogenous PI5P levels. Mice deficient for PI5P4Kβ (PI5P4Kβ−/−) have been shown to exhibit enhanced insulin sensitivity and activation of AKT in skeletal muscle.
The pharmacological modulation of PIP5KII-beta activity and/or expression is therefore believed to be an appropriate point of therapeutic intervention in pathological conditions in which cell differentiation, proliferation, and/or motility are compromised, such as cancer or inflammation, and in metabolic disorders.
Currently, there are no known therapeutic agents which effectively inhibit the synthesis of PIP5KII-beta. Inhibition of PI5P4K with small molecule inhibitors, therefore, has the potential to be a treatment for cancers and other disorders. For this reason, there remains a considerable need for novel and potent small molecule inhibitors and agents capable of effectively inhibiting PIP5KII-beta function.

The details of the invention are set forth in the accompanying description below. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, illustrative methods and materials are now described. Other features, objects, and advantages of the invention will be apparent from the description and from the claims. In the specification and the appended claims, the singular forms also include the plural unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications cited in this specification are incorporated herein by reference in their entireties.
›Definitions · 1 of 18
The articles “a” and “an” are used in this disclosure to refer to one or more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.
The term “and/or” is used in this disclosure to mean either “and” or “or” unless indicated otherwise.
The term “optionally substituted” is understood to mean that a given chemical moiety (e.g., an alkyl group) can (but is not required to) be bonded other substituents (e.g., heteroatoms). For instance, an alkyl group that is optionally substituted can be a fully saturated alkyl chain (i.e., a pure hydrocarbon). Alternatively, the same optionally substituted alkyl group can have substituents different from hydrogen. For instance, it can, at any point along the chain be bounded to a halogen atom, a hydroxyl group, or any other substituent described herein. Thus the term “optionally substituted” means that a given chemical moiety has the potential to contain other functional groups, but does not necessarily have any further functional groups. Suitable substituents used in the optional substitution of the described groups include, without limitation, halogen, oxo, —OH, —CN, —COOH, —CH 2 CN, —O—(C 1 -C 6 )alkyl, (C 1 -C 6 )alkyl, (C 1 -C 6 )alkoxy, (C 1 -C 6 ) haloalkyl, (C 1 -C 6 )haloalkoxy, —O—(C 2 -C 6 )alkenyl, —O—(C 2 -C 6 )alkynyl, (C 2 -C 6 )alkenyl, (C 2 -C 6 )alkynyl, —OH, —OP(O)(OH) 2 , —OC(O)(C 1 -C 6 )alkyl, —C(O)(C 1 -C 6 )alkyl, —OC(O)O(C 1 -C 6 )alkyl, —NH 2 , —NH((C 1 -C 6 )alkyl), —N((C 1 -C 6 )alkyl) 2 , —NHC(O)(C 1 -C 6 )alkyl, —C(O)NH(C 1 -C 6 )alkyl, —S(O) 2 (C 1 -C 6 )alkyl, —S(O)NH(C 1 -C 6 )alkyl, and S(O)N((C 1 -C 6 )alkyl) 2 . The substituents can themselves be optionally substituted. “Optionally substituted” as used herein also refers to substituted or unsubstituted whose meaning is described below.
As used herein, the term “substituted” means that the specified group or moiety bears one or more suitable substituents wherein the substituents may connect to the specified group or moiety at one or more positions. For example, an aryl substituted with a cycloalkyl may indicate that the cycloalkyl connects to one atom of the aryl with a bond or by fusing with the aryl and sharing two or more common atoms.
As used herein, the term “unsubstituted” means that the specified group bears no substituents.
Unless otherwise specifically defined, the term “aryl” refers to cyclic, aromatic hydrocarbon groups that have 1 to 3 aromatic rings, including monocyclic or bicyclic groups such as phenyl, biphenyl or naphthyl. The term “aryl” also encompasses polycyclic ring systems in which at least one ring is aromatic and is fused with 1 to 2 saturated or partially unsaturated cycloalkyl or heterocyclyl containing one or more heteroatoms selected from N, O, S, P, or B, and the cycloalkyl or heterocyclyl is optionally substituted with one or more oxo. For example, the term “aryl” may include polycyclic groups such as indanyl, Where containing two aromatic rings (bicyclic, etc.), the aromatic rings of the aryl group may be joined at a single point (e.g., biphenyl), or fused (e.g., naphthyl). The aryl group may be optionally substituted by one or more substituents, e.g., 1 to 5 substituents, at any point of attachment. Exemplary substituents include, but are not limited to, —H, halogen, —O—(C 1 -C 6 )alkyl, (C 1 -C 6 )alkyl, —O—(C 2 -C 6 )alkenyl, —O—(C 2 -C 6 )alkynyl, (C 2 -C 6 )alkenyl, (C 2 -C 6 )alkynyl, —OH, —OP(O)(OH) 2 , —OC(O)(C 1 -C 6 )alkyl, —C(O)(C 1 -C 6 )alkyl, —OC(O)O(C 1 -C 6 )alkyl, —NH 2 , NH((C 1 -C 6 )alkyl), N((C 1 -C 6 )alkyl) 2 , —S(O) 2 —(C 1 -C 6 )alkyl, —S(O)NH(C 1 -C 6 )alkyl, and —S(O)N((C 1 -C 6 )alkyl) 2 . The substituents can themselves be optionally substituted. Furthermore when containing two fused rings the aryl groups herein defined may have an unsaturated or partially saturated ring fused with a fully saturated ring. Exemplary ring systems of these aryl groups include, but are not limited to, phenyl, biphenyl, naphthyl, anthracenyl, phenalenyl, phenanthrenyl, indanyl, indenyl, tetrahydronaphthalenyl, tetrahydrobenzoannulenyl, and the like.
Unless otherwise specifically defined, “heteroaryl” means a monovalent monocyclic or polycyclic aromatic radical of 5 to 24 ring atoms, containing one or more ring heteroatoms selected from N, O, S, P, or B, the remaining ring atoms being C. Heteroaryl as herein defined also means a bicyclic heteroaromatic group wherein the heteroatom is selected from N, O, S, P, or B. Heteroaryl as herein defined also means a tricyclic heteroaromatic group containing one or more ring heteroatoms selected from N, O, S, P, or B.
