Description

FIELD OF THE INVENTION

The present invention relates to tetrahydropyrimidones which are inhibitors of fatty acid binding protein (aP2) and to a method for treating diabetes, especially Type II diabetes, as well as hyperglycemia, hyperinsulinemia, obesity, Syndrome X, diabetic complications, atherosclerosis and related diseases, and other chronic inflammatory and autoimmune/inflammatory diseases, employing such tetrahydropyrimidones alone alone or in combination with one or more types of therapuetic agents. In addition, the compounds of the present invention act as inhibitors of aldose reductase and thus are useful in the treatment of diabetic complications such as diabetic retinopathy, diabetic neuropathy and diabetic nephropathy.

BACKGROUND OF THE INVENTION

Fatty acid binding proteins (FABPs) are small cytoplasmic proteins that bind to fatty acids such as oleic acids which are important metabolic fuels and cellular regulators. Dysregulation of fatty acid metabolism in adipose tissue is a prominent feature of insulin resistance and the transition from obesity to non-insulin dependent diabetes mellitus (NIDDM or Type II diabetes).

aP2 (adipocyte fatty binding protein), an abundant 14.6 KDa cytosolic protein in adipocytes, and one of a family of homologous intracellular fatty acid binding proteins (FABPs), is involved in the regulation of fatty acid trafficking in adipocytes and mediates fatty acid fluxes in adipose tissue. G. S. Hotamisligil et al, “Uncoupling of Obesity from Insulin Resistance Through a Targeted Mutation in aP2, the Adipocyte Fatty Acid Binding Protein”, Science, Vol. 274, Nov. 22, 1996, pp. 1377-1379, report that aP2-deficient mice placed on a high fat diet for several weeks developed dietary obesity, but, unlike control-mice on a similar diet, did not develop insulin resistance or diabetes. Hotamisligil et al conclude “aP2 is central to the pathway that links obesity to insulin resistance” (Abstract, page 1377).

DIALOG ALERT DBDR928 dated Jan. 2, 1997, Pharmaprojects No. 5149 (Knight-Ridder Information) discloses that a major drug company “is using virtual screening techniques to identify potential new antidiabetic compounds.” It is reported that “the company is screening using aP2, a protein related to adipocyte fatty acid binding protein.”

DETAILED DESCRIPTION OF THE INVENTION

Compounds of the invention of general structure I may be synthesized as illustrated in the schemes set forth below.

Amine 2 is converted to carbamate 3 followed by alkylation with 3-bromomethacrylate to provide 4 . Congugate addition of 4 with the desired amine provides 5 . Removal of the Boc protecting group from 5 , with 4 N HCl/dioxane, provides 6 . Cyclization of 6 , with phosgene and triethylamine, provides cyclic urea 7 . Reduction of 7 with lithium borohydride provides alcohol 8 which is transformed into iodide 9 and then nitrile 10 . Hydrolysis of 10 provides compound I a .

Alternatively, alchohol 8 0 can be synthesized from isocyanate 11 by treatment with an appropriate amine to form urea 12 , which upon reaction with 2-chloromethyl-1-chloro-2-propene and two equivalents of sodium hydride provides cyclic urea intermediate 13 . Hydroboration of 13 provides alchohol 8 .

Alternatively I a can be formed from isocyanate 11 by treatment with para-anisole to provide urea 14 . Phase-transfer catalyzed alkylation of 14 with the known bis-mesylate 37 (see scheme 4) provides cyclic urea 15 . Cleavage of 15 and subsequent oxidation/methanolysis provides ester 16 . Removal of the methoxyphenyl protecting group by known methods (e.g., ceric ammonium nitrate) provides 17 . Reaction of 17 with an appropriate bromide provides 18 which upon saponification provides I a .

Additional compounds within formula I can be generated from compounds disclosed in schemes 1 through 3 through conversion of the substituent groups to other functionality by the usual methods of chemical synthesis, as illustrated in the following schemes 5 through 16, and the following examples. In generating such additional compounds one skilled in the art will recognize that it may be necessary to protect reactive functionality such as hydroxy, amino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in reactions. The introduction and removal of protecting groups are well known to those skilled in the art (for example see Green, T. W., “Protective Groups in Organic Synthesis”, John Wiley and Sons 1991).

In carrying our the method of the invention, a pharmaceutical composition will be employed containing the compounds of structure I, with or without another therapeutic agent, in association with a pharmaceutical vehicle or diluent. The pharmaceutical composition can be formulated employing conventional solid or liquid vehicles or diluents and pharmaceutical additives of a type appropriate to the mode of desired administration. The compounds can be administered to mammalian species including humans, monkeys, dogs, etc. by an oral route, for example, in the form of tablets, capsules, granules or powders, or they can be administered by a parenteral route in the form of injectable preparations. The dose for adults is preferably between 20 and 2,000 mg per day, which can be administered in a single dose or in the form of individual doses from 1-4 times per day.

A typical capsule for oral administration contains compounds of structure I (250 mg), lactose (75 mg) and magnesium stearate (15 mg). The mixture is passed through a 60 mesh sieve and packed into a No. 1 gelatin capsule.

A typical injectable preparation is produced by aseptically placing 250 mg of compounds of structure I into a vial, aseptically freeze-drying and sealing. For use, the contents of the vial are mixed with 2 mL of physiological saline, to produce an injectable preparation.

aP2 inhibitor activity of the compounds of the invention may be determined by use of an in vitro assay system which measures the potentiation of inhibition of aP2 by displacement of a fluorescent substrate from aP2 by the inhibitor. Inhibition constants (Ki values) for the aP2 inhibitors of the invention may be determined by the method described below:

Production of purified recombinant human aP2 protein. Recombinant human aP2 protein is produced by standard recombinant DNA technology. In the typical case, aP2 is produced by heterologous expression in E. coli strain BL21(D53) transformed with pETlla vector containing the full length human aP2 cDNA (Baxa, C. A., Sha, R. S., Buelt, M. K., Smith, A. J., Matarese, V., Chinander, L. L., Boundy, K. L., and Bernlohr, D. A. (1989). Human adipocyte lipid-binding protein: purification of the protein and cloning of its complementary DNA. Biochemistry 28: 8683-8690 and Xu, Z., Buelt, M. K., Banaszak, L. J., and Bernlohr, D. A. (1991). Expression, purification and crystallization of the adipocyte lipid binding protein. J. Biol. Chem. 266:14367-14370). Purification of aP2 from E. coli is conducted as described by Xu, yielding essentially homogeneous aP2 protein with molecular weight ˜14600 daltons and free of endogenous fatty acids. The purified aP2 is capable of binding up to one mole of free fatty acid per mole protein. The binding and structural properties of recombinant aP2 protein were previously shown to be identical to aP2 protein isolated from adipose tissue.

In vitro assay of aP2 inhibitors. Inhibitors of aP2 are evaluated in a homogeneous fluorescent-based competition assay using recombinant aP2 protein and 1,8-anilino-naphthalene-sulfonic acid (1,8-ANS) as assay substrate. This competition assay was adapted from generalized procedures described previously (Kane, C. D. and Bernlohr, D. A. (1996). A simple assay for intracellular lipid-binding proteins using displacement of 1-anilino-8-sulfonic acid. (1996) Anal. Biochem. 233:197-204 and Kurian E., Kirk, W. R. and Prendergast, F. G. (1996) Affinity of fatty acid for r-rat intestinal fatty acid binding protein. Biochemistry, 35, 3865-3874). The method relies on the increase in fluorescence quantum yield of 1,8-ANS upon binding to the fatty acid binding site of aP2. The assay is run using appropriate concentrations of inhibitor, 1,8-ANS, and aP2 protein, in order to calculate the inhibitor binding constant (Ki) for compounds being evaluated. The Ki calculation was based on the procedure previously described for calculation of dissociation constants described by Kurian. Lower Ki values indicate higher affinities of compounds binding to aP2.

In the assay as conducted for the inhibitors described herein, a series of aliquots of aP2 (5 μM) in solution in 10 mM potassium phosphate buffer (pH 7.0) are mixed with an equimolar concentration of test compound, followed by the addition of a series of increasing concentrations of 1,8-ANS (from 0 to 5 μM). The assay typically is conducted in 96-well plate format with reagents added using robotic instrumentation (Packard Multiprobe 104). The fluorescence value for each test is determined using a Cytofluor-4000 multi-well fluorescence plate reader (Perceptive Biosystems) using excitation wavelength 360 nm and emission wavelength 460 nm, or using other suitable spectrofluorometer. In preparation for the assay, test compounds are initially prepared at 10 mM in dimethylsulfoxide. All subsequent dilutions and assay additions are made in 10 mM potassium phosphate buffer, pH 7.0.

X-ray crystallography of the inhibitor-aP2 complex can be performed by one skilled in the art using contemporary biophysical methodologies and commercial instrumentation. Such crystallographic data can be used to conclusively determine if a compound used in the present invention has embodied the structural requirement necessary for inhibition of aP2. An example of such an X-ray crystallographic determination is presented below:

Crystals of aP2 complexed with the inhibitors were typically grown by the hanging drop method. aP2, at 8.3 mg/ml, was pre-equilibrated with 1-5 mM of the inhibitor in 0.1 M Tris-HCl pH 8.0, 1% w/v DMSO for four hours. 2 μl drops containing equilibrated protein and reservoir solution at a 1:1 ratio were suspended on plastic cover slips and equilibrated against a 1 ml reservoir containing 2.6-3.0M ammonium sulfate in 0.1 M Tris-HCl pH 8.0. Crystals typically appeared in 2-3 days and reached maximum size within 2 weeks. Data was typically collected on a single flash-frozen crystal (Oxford Cryosystems) using a Rigaku rotating anode and an R-axis II image plate detector of a Bruker multiwire area detector. Diffraction from aP2 crystals was excellent. Diffraction was consistently observed to better than 2.0 Å resolution often to beyond 1.5 Å resolution. Data was processed either with DENZO/SCALEPACK (R-axis II data), or Xengen (Bruker data). XPLOR was used for structure refinement and model building was done using the molecular modeling package CHAIN. After a single round of refinement, examination of the F o -F c map typically allowed facile building of the inhibitor into aP2 binding cavity. Iterative fitting and refinement were continued until improvement was no longer seen in the electron density map or R-free.

To a stirred solution of ethylene glycol (22.4 mL, 0.4 mol)in THF (200 mL) at 0° C. under argon was added sodium hydroxide (60% oil dispersion, 8.0 g, 0.2 mol) in portions over 30 min. The reaction mixture was warmed to room temperature and stirred overnight. To the resulting slurry was added a solution of t-butylchlorodiphenylsilane (52.0 mL, 0.2 mol) in THF (15 mL) in one portion. The reaction temperature rose to 35° C. before subsiding to room temperature. After 1 h, the reaction mixture was diluted with water (200 mL) and extracted three times with hexane (100 mL portions). The organic extracts were combined, washed with saturated sodium hydrogen carbonate solution, water, brine and then dried (MgSO 4 ) and evaporated. Purification by flash chromatography on silica gel (hexane, 1:2 CH 2 Cl 2 /hexanes and then 2:1 CH 2 Cl 2 /hexanes as elutants) provided 147A as a colorless oil, 48 g (80%).

To a stirred solution of 147A (47.8 g, 159 mmol), imidazole (26 g, 382 mmol) and triphenyl phosphine (45.9 g, 175 mmol) in THF (220 mL) at 5° C. under argon was added a solution of iodine (44.4 g, 175 mmol) in THF (200 mL) at such a rate as to keep the reaction temperature below 15° C. After complete addition, the reaction mixture was warmed to room temperature and stirred overnight. The reaction was quenched with 5% sodium bisulfite solution and extracted twice with Et 2 O (150 mL portions). The extracts were combined, washed with water and brine and dried (MgSO 4 ). Evaporation, followed by trituration of the residue in hexanes, filtration and re-evaporation of the filtrate gave 147B as a white solid, 57.5 g (88%), mp 43-44° C.

To a stirred solution diethyl malonate (32 mL, 210 mmol) in dry DMF (200 mL) at 0C under argon was added sodium hydride (60% mineral oil dispersion, 5.6 g, 140 mmol) in portions, maintaining the solution temperature at or below 10° C. When addition was complete, the reaction was warmed to room temperature. After stirring an additional 1 h, a solution of 147B (57.4 g, 140 mmol) in DMF (200 mL) was added at room temperature over 15 min. After 16 h, the solution was diluted with water (1 L) and extracted twice with Et 2 O (300 mL portions). The organic extracts were combined, washed with saturated sodium bicarbonate solution, water and brine, dried (MgSO 4 ) and evaporated. Purification by flash chromatography on silica gel (hexane/CH 2 Cl 2 step gradient) provided 147C as a white solid, 49.5 g (80% yield). LC/MS gave the correct molecular ion [(M+H) + =443] for the desired compound.

By the method of 59B, but using 147C product (17.50 g, 39.5 mmol), 147D was prepared as a white solid, 15.77 g, (93% yield). LC/MS gave the correct molecular ion [(M+H) + =415] for the desired compound.

To a stirred mixture of 147D (46.34 g, 112 mmol) and 2,4-dichlorobenzylamine (15.3 mL, 117 mmol) in CH 2 Cl 2 (300 mL) at 5° C. under argon was added N-ethyl-N-(N′,N-dimethylaminoethyl) carbodiimide hydrochloride (EDAC, 22.5 g, 117 mmol) over 20 min. After 30 min, the reaction mixture was warmed to room temperature and stirred for 60 h. The resulting slurry was diluted with water (500 mL) and extracted three times with CH 2 Cl 2 (200 mL portions). The combined organic extracts were washed with 10% citric acid solution (400 mL), saturated sodium bicarbonate solution (400 mL), water and brine and then filtered through a Celite pad. The filtrate was dried (MgSO 4 ) and evaporated. Purification by flash chromatography on silica gel (5:1 hexanes/EtOAc) gave 147E as a white solid, 43.5 g, (68% yield) mp 78-80° C. LC/MS gave the correct molecular ion [(M+H) + =572] for the desired compound.

To a stirred solution of 147E (43.5 g, 76 mmol) in methanol (1500 mL) at 0° C. under argon was added ammonia gas until a saturated solution was obtained. The reaction mixture was allowed to warm to room temperature and stirred under an ammonia atmosphere for 16 h. The reaction mixture was again cooled to 0° C., re-saturated with ammonia gas, warmed to room temperature and stirred an additional 20 h. Cooling, resaturation and stirring at room temperature was repeated once more. The resulting slurry was evaporated to give 147F as a white solid, 40.0 g (97% yield) mp 146-147° C. LC/MS gave the correct molecular ion [(M+H) + =542] for the desired compound.

To a solution 147F (14.0 g, 25.8 mmol) in THF (100 mL) at room temperature under argon was added a solution of borane-THF complex (1 M in THF, 200 mL, 0.2 mol) dropwise, and the solution was then refluxed. After 18 h, the solution was cooled to 5° C. and quenched by dropwise addition of sodium hydroxide solution (1 M , 220 mL, 0.22 mol) and then stirred overnight. The resulting mixture was diluted with water (200 mL) and extracted twice with Et 2 O (200 mL portions). The combined extracts were washed with water and brine, dried (Na 2 SO 4 ) and evaporated to give 147G as a colorless oil, 13.0 g, (˜100% yield). The material was used without purification for the preparation of 147H.

To a stirred solution of 147G (23.72 g, 46.0 mmol) and triethylamine (70 mL, 51 mmol) in CH 3 CN (230 mL) at 5° C. under nitrogen was added a solution of carbonyl diimidazole (CDI, 3.73 g, 23 mmol) in CH 3 CN (230 mL) over 30 min. After 1 h, solid CDI (1.24 g, 7.8 mmol) was added and, at 1 h intervals, additional CDI was added (1.24 g, 1.24 g and 1.24 g). After the last addition, the reaction mixture was warmed to room temperature and stirred for 16 h. After evaporation, the residue was partitioned between 5% potassium hydrogen sulfate solution and EtOAc (500 mL). The organic extract was dried (MgSO 4 ) and evaporated. Purification by flash chromatography on silica gel (EtOAc) gave 147H as a colorless glass, 14.9 g, (60% yield). LC/MS gave the correct molecular ion [(M+H) + =541] for the desired compound.

To a stirred solution of 147H (5.36 g, 9.90 mmol) in THF (40 mL) at room temperature under argon was added a solution of tetrabutylammonium fluoride (1 M in THF, 12 mL, 12 mmol). After 2 h, the reaction mixture was evaporated and then partitioned between water and EtOAc. The resulting white solids were collected and dried in vacuo to give 147I, 2.70 g, (90% yield) mp 152-153° C. LC/MS gave the correct molecular ion [(M+H) + =303] for the desired compound.

To a stirred suspension of 147I (5.0 g, 16.5 mmol) in acetone (120 mL) at room temperature under argon was added a saturated sodium bicarbonate solution (44 mL). The mixture was cooled to 0° C. and treated sequentially with potassium bromide (196 mg, 1.65 mmol) and TEMPO (2.71 g, 17.3 mmol). To the resulting mixture was added a solution of sodium hypochlorite (˜4%, 40.5 mL) over 15 min. After 1 h, additional sodium hypochlorite solution (15.6 mL) was added and the reaction stirred for 1 h. The reaction mixture was quenched with saturated sodium bicarbonate solution (100 mL) and extrated three times with ether (100 mL portions). The aqueous phase was separated and brought to pH 2 with solid citric acid. The resulting white solids were collected, washed with water and dried in vacuo to give 147J, 4.40 g, (84% yield) mp 206-207° C. LC/MS gave the correct molecular ion [(M+H) + =317] for the desired compound.

A stirred suspension of 147J (4.65 g, 14.7 mmol) in methanol (150 mL) at 0° C. was saturated with hydrogen chloride gas.

A mixture of phthalide (5.36 g, 40 mmol) and triphenylphosphonium dibromide (6.90 g, 40.0 mmol) was heated to 170° C. under argon for 3 h and then to 180° C. for 1 h. After cooling to room temperature, the reaction mixture was dissolved in CH 2 Cl 2 (40 mL) to give a dark brown solution. This was added to a solution of diphenylmethanol (7.37 g, 40 mmol) and N-ethyl-N,N-diisopropylamine (14 mL, 80 mmol) in CH 2 Cl 2 (40 mL) at 0° C. over 30 min. After an additional 30 min, the reaction was warmed to room temperature and stirred overnight and then evaporated. The residual material was dissolved in Et 2 O (400 mL) and the remaining solids filtered. The filtrate was washed with 10% citric acid solution (100 mL) and half-saturated sodium bicarbonate solution (100 mL). The organic extract was dried (Na 2 SO 4 ) and evaporated. Purification by flash chromatography on silica gel (1:2 CH 2 Cl 2 /hexanes as elutant) provided 186A as a colorless oil, 7.18 g (47%).
