Description

FIELD OF THE INVENTION

The present invention relates to compounds having pharmacological activity, to processes for preparation of such compounds, to pharmaceutical compositions comprising them, and to their use in therapy and prophylaxis of disease in a subject in need thereof, in particular for human and veterinarian treatments of pain, pruritus, cancer, inflammation and fibrotic diseases.

BACKGROUND OF THE INVENTION

Lysophospholipids affect fundamental cellular functions that include proliferation, differentiation, survival, migration, adhesion, invasion, and morphogensis. Abnormal functions influence many biological processes leading to disease that include, but are not limited to fibrotic disease, inflammation, cancer and peripheral nerve injury. Lysophosphatidic acid (LPA) is a lysophospholipid that has been shown to act through specific G protein-coupled receptors (GPCRs) in an autocrine and paracrine fashion. Antagonists of the LPA receptors find use in the treatment of diseases, disorders or conditions in which LPA plays a role.

Agents that interact with the lysophosphatidic acid receptors [LPARs] to reduce signal transduction through those receptors (i.e., by competitive or noncompetitive inhibition or acting as inverse agonists) reduce manifestations of the diseases described herein. Diseases and conditions whose etiology, progression or persistence is effected by in whole or in part by signaling through the lysophosphatidic acid receptor subtype 1 (LPA1R) are considered LPA-dependent. New agents having therapeutic utility for treating those LPA-dependent and other conditions and diseases described herein are needed.

SUMMARY OF THE INVENTION

Disclosed herein are compounds that inhibit the physiological activity of lysophosphatidic acid (LPA), and therefore, are useful as agents for the treatment or prevention of diseases in which inhibition of the physiological activity of LPA is useful.

In one aspect, those compounds are useful for the treatment of fibrosis of organs (e.g., liver, kidney, lung, heart and the like), liver diseases (e.g., acute hepatatis, chronic hepatitis, liver fibrosis, liver cirrhosis, portal hypertension, regenerative failure, nonalcoholic steatohepatitis (NASH), liver hypofunction, hepatic blood flow disorder, and the like), cell proliferative disease such as cancers (including but not limited to solid tumor, solid tumor metastasis, vascular fibroma, myeloma, multiple myeloma, Kaposi's sarcoma, leukemia, chronic lymphocytic leukemia (CLL), invasive metastasis of cancer cell, and the like), inflammatory diseases (including but not limited to psoriasis, nephropathy, pneumonia and the like), gastrointestinal tract disease (including but not limited to (irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), abnormal pancreatic secretion, and the like), renal disease, urinary tract-associated disease (including but not limited to benign prostatic hyperplasia or symptoms associated with neuropathic bladder disease, spinal cord tumor, hernia of intervertebral disk, spinal canal stenosis, symptoms derived from diabetes, lower urinary tract disease (including but not limited to obstruction of lower urinary tract, and the like), inflammatory disease of lower urinary tract, (including but not limited to dysuria, frequent urination, and the like), pancreas disease, abnormal angiogenesis-associated disease (including but not limited to arterial obstruction and the like), scleroderma, brain-associated disease (including but not limited to cerebral infarction, cerebral hemorrhage, and the like), nervous system diseases (including but not limited to neuropathic pain, peripheral neuropathy, pruritus and the like), ocular disease (including but not limited to age-related macular degeneration (AMD), diabetic retinopathy, proliferative vitreo-retinopathy (PVR), cicatricial pemphigoid, glaucoma filtration surgery scarring, and the like).

“Protecting group” as used here means a moiety that prevents or reduces the ability of the atom or functional group to which it is linked from participating in unwanted reactions. Non-limiting examples are for —ORPR, wherein RPR is a protecting group for the oxygen atom found in a hydroxyl, while for —C(O)—ORPR, RPR may be a carboxylic acid protecting group; for —SRPR, RPR may be a protecting group for sulfur in thiols and for —NHRPR or —N(RPR)2—, at least one of RPR is a nitrogen atom protecting group for primary or secondary amines. Hydroxyl, amine, ketones and other reactive groups may require protection against reactions taking place elsewhere in the molecule. The protecting groups for oxygen, sulfur or nitrogen atoms are usually used to prevent unwanted reactions with electrophilic compounds, such as acylating agents. Typical protecting groups for atoms or functional groups are given in Greene (1999), “Protective groups in organic synthesis, 3rd ed.”, Wiley Interscience.

Typically, carbamate groups as used here comprise or consist of an organic moiety containing about 1-50 carbon atoms, 1-20 carbon atoms or 1-8 carbon atoms and 0 to 10 independently selected heteroatoms (e.g., O, S, N, P, Si), typically 0-2, bonded through the —O—C(═O)—NRPR- structure, e.g., organic moiety-O—C(═O)—NRPR— or —O—C(═O)—NRPR-organic moiety. When carbamate is used as a Markush group (i.e., a substituent) the singly bonded oxygen (O-linked) or nitrogen (N-linked) of the carbamate functional group is attached to a Markush formula with which it is associated. The linkage of the carbamate substituent is either explicitly stated (N- or O-linked) or implicit in the context to which this substituent is referred.

For any substituent group or moiety described by a given range of carbon atoms, the designated range means that any individual number of carbon atoms is described. Thus, reference to, e.g., “C1-C4 optionally substituted alkyl”, “C2-6 alkenyl optionally substituted alkenyl”, “C3-C8 optionally substituted heterocycle” specifically means that a 1, 2, 3 or 4 carbon optionally substituted alkyl moiety as defined herein is present, or a 2, 3, 4, 5 or 6 carbon alkenyl, or a 3, 4, 5, 6, 7 or 8 carbon moiety comprising a heterocycle or optionally substituted alkenyl moiety as defined herein is present. All such designations are expressly intended to disclose all of the individual carbon atom groups and thus “C1-C4 optionally substituted alkyl” includes, e.g., 3 carbon alkyl, 4 carbon substituted alkyl and 4 carbon alkyl, including all positional isomers and the like are disclosed and can be expressly referred to or named. For esters, carbonates and carbamates defined by a given range of carbon atoms, the designated range includes the carbonyl carbon of the respective functional group. Thus a C1 ester refers to a formate ester and a C2 ester refers to an acetate ester. The organic substitutents, moieties and groups described herein, and for other any other moieties described herein, usually will exclude unstable moieties except where such unstable moieties are transient species that one can use to make a compound with sufficient chemical stability for the one or more of the uses described herein. Substituents, moieties or groups by operation of the definitions herein that results in those having a pentavalent carbon are specifically excluded.

Example 1

1-(4-{4-[1-(2-Chloro-phenyl)-ethoxycarbonylamino]-3-methyl-isoxazol-5-yl}-benzoylamino)-cyclopropanecarboxylic acid

Step 1: 2-(4-carboxymethyl-benzoyl)-3-oxo-butyric acid t-butyl ester

t-Butyl acetoacetate (15.1 mL, 89.0 mmol) was added to a suspension of magnesium chloride (8.48 g, 89.0 mmol) in dichloromethane (88 mL) that had been cooled to 0° C. To the mixture was added pyridine (13.8 mL, 171 mmol) and stirring continued for an additional 15 minutes. 4-(Chlorocarbonyl)benzoic acid methyl ester (17.0 g, 85.6 mmol) in dichloromethane (88 mL) was then added dropwise to the reaction. This mixture was stirred at 0° C. for 90 minutes and then at room temperature for 90 minutes. At this time the mixture was treated with 0.2M hydrochloric acid solution (10 mL). The organic layer was diluted with dichloromethane (70 mL), washed with 0.2M hydrochloric acid solution (30 mL), separated, dried over anhydrous Na2SO4, filtered and concentrated in vacuo. A yellow oil was obtained that was used directly in the next step (17.1 g, 68%). Method 2, Rt 5.4 min. MS (ESI) m/z 321.2 [M+H+].

Step 2: 5-(4-Methoxycarbonyl-phenyl)-3-methyl-isoxazole-4-carboxylic acid tert-butyl ester

5-(4-methylcarboxy-phenyl)-3-methyl-isoxazol-4-yl-carboxylic acid t-butyl ester A mixture of 2-(4-carboxymethyl-benzoyl)-3-oxo-butyric acid t-butyl ester [example 1, step 1] (7.45 g, 23.2 mmol), hydroxylamine hydrochloride (5.17 g, 74.4 mmol), ethanol (46.5 mL) and water (32.2 mL) was heated at 60-62° C. for 2 hours. At this point the reaction was allowed to cool and the resulting mixture was partitioned between ethyl acetate and water. The organic layer was dried over anhydrous MgSO4, filtered and concentrated in vacuo. A crude product was obtained that was purified by silica gel chromatography initially with hexane/ethyl acetate 9/1 as eluting solvent to afford 5-(4-Methoxycarbonyl-phenyl)-3-methyl-isoxazole-4-carboxylic acid tert-butyl ester (4.69 g, 64%)

Method 2, Rt 6.14 min. MS (ESI) m/z 318.2 [M+H+].

Step 3: 5-(4-Methoxycarbonyl-phenyl)-3-methyl-isoxazole-4-carboxylic acid

5-(4-Methoxycarbonyl-phenyl)-3-methyl-isoxazole-4-carboxylic acid tert-butyl ester [Example 1, step 2] (6.35 g mg, 20 mmol) was dissolved in dichloromethane (100 mL) and to this was added trifluoroacetic acid (50 mL). The mixture was stirred for 2 hours at room temperature when the volatiles were removed. The product (5.2 g, 99%) was used as is in Step 4.

Method 2, Rt 4.08 min. MS (ESI) m/z 262 [M+H+];

Step 4: 1-(4-{4-[1-(2-Chloro-phenyl)-ethoxycarbonylamino]-3-methyl-isoxazol-5-yl}-benzoic acid methyl ester

5-(4-methylcarboxy-phenyl)-3-methyl-isoxazol-4-yl-carboxylic acid [Example 1, step 3] (3.91 g, 15.0 mmol) was suspended in toluene (120 mL) and to this was added diisopropylethylamine (3.13 mL, 18.0 mmol). To the resulting solution was added diphenylphosphoryl azide (3.56 mL, 16.5 mmol) and this mixture was heated to 90° C. After 15 minutes, 1-(2-chlorophenyl)-ethanol (2.98 mL, 22.5 mmol) was added slowly and heating maintained for 4 hours. The reaction was allowed to cool overnight. This mixture was diluted with toluene, transferred to a separatory funnel, extracted with water. The organic layer was dried over anhydrous MgSO4, filtered and concentrated in vacuo to yield a crude product (8.34 g).

Compounds 57-458 of Table 1 and derivatives thereof are prepared from the according to procedures outlined for compounds 1-56. The heterocyclic amines or esters required to assemble the corresponding carbamates were prepared based on methods described in citations 1-24.

Certain isoxazole substitutions are prepared following construction of the appropriate aryl isoxazole (3, Scheme 1). Direct flurorination or bromination and cyanation provides arylbromide (4) or acid (5) after palladium catalyzed carbonylation.

Acid (5, scheme 2) may be directly coupled with amines to afford amide intermediates (6) which may be converted to the carbamate products (7) following acid hydrolysis, Curtius rearrangement and deprotection with acid.

The acid (5) may be reduced to alcohol (8) and/or converted to its chloride (9) as in scheme 3. Alcohols may be converted to their ether analogs (10) by rhodium catalyzed insertion into diazo intermediates 2N+-z-RB, or the amines (11) may be generated from chlorides (IX)

Alternatively the bromides (4) may be directly coupled to alcohols or amines (UV—Z—RB) whereby U is —OH or —NH2 by thermal or metal catalyzed halide displacement as in scheme 4. All key intermediates (10-12) may be further modified to produce final products as described in scheme 1 using acid hydrolysis, Curtius rearrangement followed by acid deprotection

Example 57

Receptor Binding Assays

Binding affinity of compounds of Formula I-XII were determined based on their ability to displace tritiated lysophosphatidic acid ([3H]-LPA) from CHO cells expressing LPA1R in a protocol similar to that described in reference 17. In a 96 well format, CHO cells expressing human LPA1R [Cerep] were treated with [3H]-LPA (2 nM). Test compounds were added in increasing concentration to each well and incubated at room temperature for 90 minutes. At this time the plates were washed and the wells counted for radioactivity. Results were compared to a control in which cells were treated with [3H]-LPA in the presence of 10 μM unlabeled LPA. The specific ligand binding to the receptors was defined as the difference between the total binding and the nonspecific binding determined in the presence of an excess of unlabelled ligand. The results were expressed as a percent of control specific binding ((measured specific binding/control specific binding)×100) and as a percent inhibition of control specific binding (100−((measured specific binding/control specific binding)×100)) obtained in the presence of the test compounds. The IC50 value (concentration causing a half-maximal inhibition of control specific binding) and Hill coefficient (nH) were determined by non-linear regression analysis of the competition curve generated with mean replicate values using Hill equation curve fitting (Y=D+[(A−D)/(1+(C/C50)nH)], where Y=specific binding, D=minimum specific binding, A=maximum specific binding, C=compound concentration, C50=IC50, and nH=slope factor). This analysis was performed using a software developed at Cerep (Hill software) and validated by comparison with data generated by the commercial software SigmaPlot® 4.0 for Windows® (© 1997 by SPSS Inc.). The inhibition constant (Ki) was calculated using the Cheng Prusoff equation (Ki=IC50/(1+(L/KD)), where L=concentration of radioligand in the assay, and KD=affinity of the radioligand for the receptor). A scatchard plot was used to determine the Kd.

Example 58

Calcium Flux Assay

Inhibition of LPA-stimulated Ca2+ flux was used to assess compound potency using FLIPR technology in a 96 well plate format. The assay buffer used was a modified Hanks Balanced Salt Solution (HBSS) where HBSS was supplemented to contain 20 mM HEPES and 2.5 mM Probenecid at pH7.4 (Millipore, GPCR Profiler®). LPA1R expressing cells (Millipore) were plated and prepared 24 hours prior to assay of test articles. Ca2+ ion flux was assessed from fluorescence of a Fluo-based No Wash Ca2+ dye. Antagonist data are generated from plates with LPA concentrations sufficient to generate 80% efficacy [EC80]. Percentage inhibition was calculated from a reduction of efficacy according to concentration of compounds of Formula I-VI. For dose responses the inhibition data was used to calculate compound IC50.

The agonist assay was conducted on a FLIPRTETRA instrument where the test compound(s), vehicle controls, and reference agonist were added to the assay plate after a fluorescence baseline was established. The agonist assay was a total of 180 seconds and was used to assess each compound's ability to activate each GPCR assayed. Upon completion of the agonist assay, the assay plate was removed from the FLIPRTETRA and incubated at 25° C. for seven (7) minutes. After the incubation period, the assay plate was placed back in the FLIPRTETRA and the antagonist assay was initiated.

Antagonist Assay: Using EC80 potency values determined during the agonist assay, all pre-incubated sample compound wells were challenged with EC80 concentration of reference agonist after establishment of a fluorescence baseline. The antagonist assay was conducted using the same assay plate that was used for the agonist assay. The antagonist assay was conducted on a FLIPRTETRA instrument where 9 vehicle controls and EC80 concentration of reference agonist were added to appropriate wells. The antagonist assay was a total of 180 seconds and was used to assess each compound's ability to inhibit each GPCR assayed.

Data Processing: All assay plate data were subjected to appropriate baseline corrections. After baseline corrections were applied, maximum fluorescence values were exported and data processed to calculate percentage activation (relative to Emax reference agonist and vehicle control values), percentage inhibition (relative to EC80 and vehicle control values), and additional statistical values (i.e. Z′, percentage variation between replicate data values) to assess the quality of each plate. Where assay plate data were rejected, additional experiments were conducted. All dose response curves were generated using Graph Pad Prism. The curves were fit by utilizing “Sigmoidal Dose Response (Variable Slope)” equation where the bottom parameter was fixed to “0.” Where appropriate, the top parameter was fixed to “100” to better predict potency values when a full curve was not generated by the concentrations assayed.

Antagonist activity data for representative compounds prepared according to the synthetic methods disclosed herein are presented in Table 2.
