This application claims the benefit under 35 U.S.C. §119(e) to co-pending U.S. provisional application No. 60/494,330, filed Aug. 11, 2003, which is hereby incorporated by reference in its entirety.

›BACKGROUND OF THE INVENTION

In the human pharmaceutical arts, the rapidly developing resistance of known bacterial strains to currently prescribed pharmaceuticals has initiated a vigorous search for new classes of antibacterial agents having alternative modes of action. For example, methicillin resistant S. aureus (MRSA), vancomycin resistant Enterococcus (VRE) and penicillin resistant S. pneumo (PRSP) are bacterial strains which do not respond well to current clinical drug therapies.

Peptidoglycan is an essential cell wall polymer which forms a sacculus around the bacterial cell. The biosynthesis of peptidoglycan provides a unique and selective target for antibacterial activity. Peptidoglycan biosynthesis requires ten specific enzymes to perform as many synthetic transformations. These enzymes include MurA, MurB, MurC, MurD, MurE, MurF, MurG, MraY and the transglycosylase and transpeptidase families of enzymes. Inhibition of any one of these essential enzymes leads to loss of cell shape and integrity followed by bacterial death. This applies to both Gram positive and Gram negative microorganisms (Bugg, T. D. et al., Natural Products Reports 1992 199-215). Of these ten essential enzymes, β-lactam antibiotics inhibit transpeptidases, vancomycin inhibits transglycosylases and fosfomycin inhibits MurA.

In the animal health arts, virtually all commercial and most companion animals are affected by ecto-and endoparasites. The outcome associated with said parasitic infection or infestation in said animals is generally clinical disease and subclinical conditions that decrease performance. Insects, such as Phthiraptera (lice) and Diptera (flies), are among the most economically important ectoparasites in animal production. Insects, such as Siphonáptera (fleas), are highly pesteriferous to companion animals. Helminths, such as Trichostrongylus colubriformis, Haemonchus contortus , or the like, are among the most economically important endoparasites in animal production. Nematodes are highly pesteriferous to companion animals. Ecto- and endoparasitic infections and infestations not only seriously effect the economies of raising livestock for meat, wool, hides and milk, but are also a source of great concern for companion animals. New, economic alternative methods and compositions for the prevention, treatment and control of ecto- or endoparasites in warm-blooded animals are constantly being sought.

Therefore, it is an object of this invention to provide compounds which inhibit the Mur family of enzymes and are useful as antibacterial agents, particularly against resistant strains of bacteria.

It is another object of this invention to provide therapeutic methods and pharmaceutical compositions for the treatment of bacterial infection or disease.

It is also an object of this invention to provide an effective method for the prevention, treatment or control of ecto- or endoparasitic infection or infestation in homeothermic animals.

It is a further object of this invention to provide an ecto- or endoparasiticidal composition suitable for use on animals and humans.

It is a feature of this invention that the compounds provided herein act as effective inhibitors of bacterial cell wall biosynthesis via the Mur enzyme pathway.

Other objects and features of the invention will become more apparent by the detailed description set forth hereinbelow.

›DETAILED DESCRIPTION OF THE INVENTION · 1 of 8

Many known antibiotics such as the cephalosporins, the penicillins and vancomycin inhibit the biosynthesis of peptidoglycan, an essential cell wall component of both Gram positive and Gram negative bacteria. These antibiotics inhibit membrane-bound enzymes involved in the crosslinking of the cell wall, i.e., the transpeptidation step. Earlier steps in bacterial cell wall biosynthesis have not been the target of action for current commercial antibiotics, with the exception of fosfomycin. These earlier cytoplasmic steps involve biosynthetic conversions which require the MurA through MurF enzymes. Few inhibitors of the enzymes are known to possess antibacterial activity.

Surprisingly, it has now been found that 3-aryl-4-hydroxyfuranone compounds of formula I inhibit bacteria cell wall biosynthesis via the Mur enzyme pathway. Advantageously, said hydroxyfuranone compounds are effective therapeutic agents against bacterial infection or disease, particularly against infection or disease caused by resistant strains of bacteria. Accordingly, the present invention provides 3-aryl-4-hydroxyfuranone compounds of formula I

wherein

a stereoisomer thereof, a tautomer thereof or a pharmaceutically acceptable salt thereof.

As used in the specification and claims, the term halogen designates Br, Cl, I or F and the term aryl designates a carbocyclic aromatic ring system such as phenyl, naphthyl, anthracenyl or the like, preferably phenyl. The term heteroaryl, as used herein, designates a 5- to 10-membered aromatic ring system containing 1, 2 or 3 heteroatoms, which may be the same or different, selected from N, O or S.

Ecto- and endoparasiticidal infection and infestation are a constant problem in animal husbandry and in the care and raising of companion animals. Important agronomic and companion animals such as cattle, sheep, horses, goats, pigs, camels, water buffalo, donkeys, rabbits, fallow deer, reindeer, minks, chinchillas, racoons, chickens, geese, turkeys, ducks, dogs, cats or the like are prone to attack and infestation by biting and sucking ectoparasitic insects such as Diptera, Muscidae or Siphonáptera. Helminthiases is a widespread disease found in many farm and companion animals including cattle, sheep, swine, horses, poultry, fish, rabbits, goats, dogs, cats, or the like, as well as in humans. Among the helminths, which cause significant damage are trematodes such as Faciola hepatica or nematodes such as Trichostrongylus colubriformis, Haemonchus contortus and the like. Surprisingly, it has now been found that 3-aryl-4-hydroxyfuranone compounds of formula I wherein R is H, COR 4 or a C 1 -C 6 alkyl, C 3 -C 6 cycloalkyl, C 2 -C 6 alkenyl, C 2 -C 6 alkynyl, benzyl, aryl or heteroaryl group each optionally substituted, may be used to control, prevent, ameliorate or effectively treat infection and infestation of ectoparasites such as Diptera, Muscidae or Siphonáptera, or endoparasites such as helminths, including nematodes in animals and humans. Advantageously, said hydroxyfuranone compounds may be particularly effective for controlling, preventing or treating infection or infestation of resistant strains of ecto- or endoparasites.

Accordingly, in another embodiment of the invention, there is provided a method for the prevention, amelioration or control of ecto- or endoparastic infection or infestation in a homeothermic animal which comprises administering to said animal a prophylactically, therapeutically, or pharmaceutically effective amount of a 3-aryl-4-hydroxyfuranone compound of formula I

Ectoparasitic insects which may be controlled, ameliorated or treated by the animal health method of invention include Diptera, Muscidae or Siphonáptera, in particular, Diptera: Muscidae such as Musca autumnalis (face flies), Haemtobia irritans (horn flies) Stomoxys calcitrans (stable flies), heel flies, tsetse flies, blow flies or the like. Said insects are breeders of filth and vectors of disease and are serious ectoparasitic pests of important agronomic animals such as cattle, horses and sheep. Further, Diptera : Hippoboscidae (louse flies) such as Melophagus ovinus (sheep ked), which is a serious parasite of sheep are problematic in animal production.

Among the Phthiraptera families known to be ectoparasites of animals are: Trichodectidae such as Bovicola bovis (important cattle-biting louse), B. ovis (sheep-biting louse) or B. equi (horsebiting louse); Haematopinidae such as Haematopinus suis (hog louse), or H. asini (horse sucking louse); Linognathidae such as Linognathus stenopsis (goat sucking louse) or L. vitali (long-nosed cattle louse); or the like.

One of the Siphonáptera families known to infest companion animals is Pulicidae such as Archaeopsyllniae (cat and dog fleas), Spilopsyllinae (rabbit fleas), or the like.

Endoparasitic infections which may be controlled, ameliorated or treated by the method of the invention include those Helminthiases infections caused by the class Trematoda, commonly known as flukes or flatworms or by the class Nematoda, commonly known as nematodes or roundworms. The method of the invention is particularly effective against infection caused by Trematoda, especially members of the genera Fasciola, Fascioloides, Paramphistomum, Dicrocoelium, Eurytrema, Ophisthorchis, Fascioiopsis, Echinostoma , or Paragonimus . The method of the invention is uniquely effective against trematodes and may provide significant control of the economically important Faciola hepatica , commonly known as liver fluke. Helminthiases infection is also caused by a group of worms referred to as nematodes. Nematodes cause serious damage to the walls and tissues of the organs in which they reside, including the intestinal tract, heart, lungs and blood vessels, and are a primary cause of anemia. If left untreated they may result in death to the infected host. The nematodes most commonly found to be the infecting agents of warm-blooded animals include Haemonchus, Ostertagia, Cooperia, Drofilaria, Oesphagastomum, Nematodirus and Dictyocaulus.

In addition to helmintic infection, the present method of invention is also useful for the control of endoparasitic arthropod infestations such as cattle grub. The method of invention is also effective against infection caused by nematodes such as, T. colubriformis, H. contortus , or the like.

Homeothermic animals suitable for use in the method of invention are all warm-blooded animals susceptible to ecto- or endoparasitic infection or infestation including farm animals such as cattle, sheep, swine, horses, poultry, rabbits, goats, or the like, preferably cattle, sheep, swine or horses; companion animals such as dogs, cats, gerbils, rabbits, birds or the like, preferably dogs or cats; or humans.

The effective amount of the formula I compound to be used in the animal health method of invention will vary according to the specific compound used, the mode of application used, the identity of the parasite to be controlled, the degree of infection or infestation, the extent of the parasite population, the nature of the target host, the weather conditions or the like. Effective dosages may range from 0.1 mg/kg to 100 mg/kg, preferably about 1.0 mg/kg to 50 mg/kg. Naturally, quantities of greater than effective amounts of said formula I compound may be administered, but are not required for the protection of the target animals from the ecto- or endoparasite.

Compounds of formula I may be administered to the target homeothermic animal orally, topically or parenterally, preferably orally. For example, the formula I 3-aryl-4-hydroxyfuranone compound may be administered to said animal in or with their drinking water or as a feed additive or in the form of a pill, tablet, bolus, implant, capsule or drench. The formula I compound may also be administered topically by applying said compound to the skin, hide or hair of the homeothermic animal. Parenteral administration, i.e., intramural, intramuscular or subcutaneous injection is also suitable for the inventive method.

Walsh in Biochemistry 33, 10646-10651, is used to evaluate the inhibitory activity of test compounds against MurA, the enzyme which catalyzes the first step of bacterial cell wall biosynthesis. Experiments are performed by adding a solution of test compound (in a mixture of dimethylsulfoxide and water) and an enzyme solution to a well. After a pre-incubation period of 10 mintues at 37° C., Tris/BME buffer and assay buffer are added. A start point optical density (OD 0 ) reading is taken at 340 nm immediately following the addition of assay buffer. After incubation for 1 hr at 37° C., the stop solution is added and the color is allowed to develop for 30 minutes. An end point OD 1 reading at 660 nM is then taken. The % inhibition at a concentration of 25 μg/ml is calculated for each test compound using the formula:

Using these values, the concentration required to give 50% inhibition (IC 50 ) for each test compound is determined by linear regression analysis. The results are shown in Table III.

Dilute 17.5 uL of aqueous 5 mM BME (2-mercaptoethanol) to 50 mL with 50 mM Tris/HCl (pH 8.0).

Preparation of Enzyme Solution:

Dilute aqueous MurB stock solution (0.94 mg/mL) with 200 parts 50 mM Tris/2-BME buffer. The final MurB concentration is 4.7 μg/mL.

Synthesis of Substrate for MurB (MurA Product EP-UDP-GluNAc):

A mixture of 13 mg UDP-N-acetylglucosamine and 5.5 mg phosphoenolpyruvate are dissolved in 10 mL Tris/BME buffer forming 2 mM concentrations of each reagent in solution. The solution is incubated with 300 μg purified MurA at 37° C. overnight to give approximately 70-80% product yield.

The assay buffer is prepared in water from reagents with the following final concentrations: 100 mM Tris/HCl (pH 8.0), 200 μM NADPH, 100 μM MurB substrate, 10 μM 2-mercaptoethanol, and 10 μM KCl.

A procedure similar to that described by Dhalla et al., in Biochemistry 1995, 34, 5390, is used to evaluate the inhibitory activity of test compounds against MurB, the enzyme which catalyzes the second step of bacterial cell wall biosynthesis. Experiments are performed by adding 20 μL of a solution of test compound in a mixture of dimethylsulfoxide and water and 30 μL of enzyme solution to a well. After a pre-incubation period of 20 mins. at 23° C., 50 μL of Tris/BME buffer and 100 μL of assay buffer are added. A start point optical density (OD 0 ) reading is taken at 340 μM immediately following the addition of assay buffer using a Molecular Devices Spectra Max 250 with SoftMax software. After a 20 min. incubation period at 23° C., an endpoint OD 1 reading is taken at 340 μM. Controls are performed using the same procedure and employing 20 μL of a blank dimethylsulfonide and solvent mixture in place of the test compound solution. The % inhibition at concentrations of 10 μg/ml and 25 μg/ml are calculated using the formula:

After a pre-incubation period of 10 mins. at 23° C., 3.75 μl of a 0.75 μM solution of UDP-MurNac is added to each well. Following an incubation period of 10 mins. at 37° C., 210 μl stop solution and 50 μl of a 34% w/v sodium citrate solution are added and color is allowed to develop for 10 mins. at 23° C. (Lanzetta et al., Analytical Biochemistry, 1979, 95) Optical density readings are taken at 660 nm using a Molecular Devices Spectra Max 250 with Soft Max software. Controls are performed using the same procedure and omitting the addition of UDP-MurNac. The % inhibition of a concentration of 25 μg/ml is calculated for each test compound using the formula:

In Vivo Evaluation of the Efficacy of Test Compounds Against T. colubriformis

In this evaluation, gerbils are infected with Trichostrongylus columbriformis infective larvae at a concentration of approximately 800 L 3 /mL. Larvae for gerbil infections are cultured from feces from sheep previously infected with T. colubriformis . One week post infection, test compounds are administered by gavage as a single oral dose of 50 mg/kg of body weight. For each group of 3 gerbils, 10 mg of test compound are dissolved in 2 mL of PEG 400:DMSO (1:2 v/v) and each animal is administered the test solution at a rate of 0.1 mL/10 g of body weight. Treatments are randomly allocated to groups of 3 infected gerbils each; 35 groups are treated with test compounds; 4 groups are untreated (administered vehicle only) as a negative control; and one group is treated with a known endectoside, NEMADECTIN as a positive control. All animals are observed daily for morbidity and mortality. Four days post-treatment, all animals are weighed and necropsied. Worm counts are conducted with the use of stereoscopes and counters. The results are recorded as % mortality as compared to that of the negative control for the worms. Toxicity is indicated for those groups having one or more animals expired or demonstrating significant weight loss as compared to the negative control. The data are shown in Table VIII, wherein all test compounds are the Z isomer, unless otherwise noted.
