Description: HETERQARYL UREA NEUROPEPTIDE Y Y5 RECEPTOR ANTAGONISTS This invention relates to heteroaryl urea neuropeptide Y Y5 receptor antagonists useful in the treatment of eating disorders, pharmaceutical compositions containing the compounds, and methods of treatment using the compounds. Neuropeptide Y (NPY) is a 36 amino acid neuropeptide that is widely distributed in the central and peripheral nervous systems. NPY is a member of the pancreatic polypeptide family that also includes peptide YY and pancreatic polypeptide (Wahlestedt, C, and Reis, D., Ann. Rev. Toxicol., 32, 309, 1993). NPY elicits its physiological effects by activation of at least six receptor subtypes designated Y1 , Y2, Y3, Y4, Y5 and Y6 (Gehlert, D., Proc. Soc. Exp. Biol. Med., 218, 7, 1998; Michel, M. et al., Pharmacol. Rev., 50, 143, 1998). Central administration of NPY to animals causes dramatically increased food intake and decreased energy expenditure (Stanley, B. and Leibowitz, S., Proc. Natl. Acad. Sci. USA 82: 3940, 1985; Billington et al., Am J. Physiol., 260, R321 , 1991 ). These effects are believed to be mediated at least in part by activation of the NPY Y5 receptor subtype. The isolation and characterization of the NPY Y5 receptor subtype has been reported (Gerald, C. et al., Nature, 1996, 382, 168; Gerald, C. et al. WO 96/16542). Additionally, it has been reported that activation of the NPY Y5 receptor by administration of the Y5 - selective agonist [D-Trp 32 ]NPY to rats stimulates feeding and decreases energy expenditure (Gerald, C. et al., Nature, 1996, 382, 168; Hwa, J. et al., Am. J. Physiol., 277 (46), R1428, 1999). Hence, compounds that block binding of NPY to the NPY Y5 receptor subtype should have utility in the treatment of eating disorders such as obesity, bulimia nervosa, anorexia nervosa, and in the treatment of disorders associated with obesity such as type II diabetes, insulin resistance, hyperlipidemia, and hypertension. Published PCT patent application WO 00/27845 describes a class of compounds, characterized therein as spiro-indolines, said to be selective neuropeptide Y Y5 receptor antagonists and useful for the treatment of obesity and the complications associated therewith. Known urea derivatives indicated as possessing therapeutic activity are described in U.S. Patent Nos. 4,623,662 (antiatherosclerotic agents) and 4,405,644 (treatment of lipometabolism). Provisional application, U.S. Serial No. 60/232,255 describes a class of substituted urea neuropeptide Y Y5 receptor antagonists.

Except where stated otherwise, the following definitions apply throughout the present specification and claims. Additionally, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs. These definitions apply regardless of whether a term is used by itself or in combination with other terms. Hence the definition of "alkyl" applies to "alkyl" as well as to the "alkyl" portions of "alkoxy", etc. Alkyl represents a straight or branched saturated hydrocarbon chain having the designated number of carbon atoms. Where the number of carbon atoms is not specified, 1 to 6 carbons are intended. Halo represents fluoro, chloro, bromo or iodo. Aryl refers to a mono- or bicyclic ring system having one or two aromatic rings including, but not limited to, phenyl, naphthyl, tetrahydronaphthyl, indanyl, and the like. The aryl group can be unsubstituted or substituted with one, two, or three substituents independently selected from lower alkyl, halo, cyano, nitro, haloalkyl, hydroxy, alkoxy, carboxy, carboxamide, mercapto, sulfhydryl, amino, alkylamino and dialkylamino. Heteroaryl refers to 5- to 10-membered single or benzofused aromatic rings consisting of 1 to 3 heteroatoms independently selected from the group consisting of -O-, -S-, and -N=, provided that the rings do not possess adjacent oxygen and sulfur atoms. The heteroaryl group can be unsubstituted or substituted with one, two, or three substituents independently selected from lower alkyl, halo, cyano, nitro, haloalkyl, hydroxy, alkoxy, carboxy, carboxamide, mercapto, sulfhydryl, amino, alkylamino, dialkylamino. When a variable appears more than once in the structural formula, the identity of each variable appearing more than once may be independently selected from the definition for that variable. N-oxides can form on a tertiary nitrogen present in an R substituent, or on =N- in a heteroaryl ring substituent and are included in the compounds of Formula I. The expression "prodrug" refers to compounds that are drug precursors which following administration, release the drug in vivo via some chemical or physiological process (e.g., a prodrug on being brought to the physiological pH or through enzyme action is converted to the desired drug form). The term "chemically stable compound" is defined as a compound that can be isolated, characterized, and tested for biological activity. For compounds of the invention having at least one asymmetrical carbon atom, all isomers, including diastereomers, enantiomers and rotational isomers are contemplated as being part of this invention. The invention includes d and I isomers in both pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional techniques, either by reacting optically enriched or optically pure starting materials or by separating isomers of a compound of Formula I. Compounds of Formula I can exist in unsolvated and solvated forms, including hydrated forms. In general, the solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like, are equivalent to the unsolvated forms for purposes of this invention. A compound of Formula I may form pharmaceutically acceptable salts with organic and inorganic acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those skilled in the art. The salts are prepared by contacting the free base forms with a sufficient amount of the desired acid to produce a salt in the conventional manner. The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution, such as dilute aqueous sodium hydroxide, potassium carbonate, ammonia or sodium bicarbonate. The free base forms differ from their respective salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the salts are otherwise equivalent to their respective free base forms for purposes of the invention. In a preferred group of compounds of Formula I, the heterocyclic group attached to 2 is In particular, the preferred group includes the above compounds wherein R 1 is hydrogen, R 2 is hydrogen or -(d-C 6 )alkyl, R 4 , R 5 , R 6 and R 7 are independently hydrogen or halogen, R 8 is 1-3 substitutents independently selected from the group consisting of H, halogen, -O(d-C 6 )alkyl, -OH, polyhaloalkyl and polyhaloalkoxy, R 9 is -SO 2 (d-C 6 )alkyl, -SO 2 (C 3 -C 7 )cycloalkyl, -SO 2 (C 1 -C 6 )alkyl(C 3 -C 7 )cycloalkyl, -SO 2 aryl, ■ SO 2 heteroaryl, -SO 2 NR 13 R 14 , -CO(d-C 6 )alkyl, -CO(C 3 -C 7 )cycloalkyl, -CO(C C 6 )alkyl(C 3 -C 7 )cycloalkyl, -C(O)aryl, -C(O)heteroaryl, aryl or heteroaryl, R 10 is H or alkyl, R 1 is -SO 2 (CrC 6 )alkyl, Q is -OR 13 or -NR 13 R 14 , R 13 and R 14 are independently selected from H or -(CrC 6 )alkyl, the sum of j and k is 2 or 3 and the sum of I and m is 2 or 3. Another aspect of this invention is a method of treating a patient having a disease or condition mediated by NPY by administering a therapeutically effective amount of a compound of Formula I, a prodrug thereof, or a pharmaceutically acceptable salt of said compound or of said prodrug to the mammal. It is preferred that the receptor is the NPY-5 receptor. Another aspect of this invention is directed to a method of treating obesity comprising administering to a patient in need of such treatment a therapeutically effective amount of a compound of Formula I or a prodrug thereof, or a pharmaceutically acceptable salt of said compound or of said prodrug.

Compounds of Formula I may be produced by processes known to those skilled in the art and as shown in the following reaction schemes and in the preparations and examples below. Scheme 1 A - r NH 2 E Λ X* "Suzuki coupling" E = halo PG = protecting group Z-B(OH) 2 1. deprotect 2. acyl halide, sulfonyl halide, isocyanate In Scheme 1 , a nitro heteroaryl halide is coupled to an aryl boronic acid to give a nitro-substituted biaryl derivative. Reduction of the nitro group gives a biaryl amine derivative. Alternatively, an amino heteroaryl halide derivative is coupled to an aryl boronic acid derivative to directly give an amino biaryl derivative. Treatment of the biaryl amine with a reagent such as phenyl chloroformate, 4-nitrophenyl chloroformate, triphosgene, or N,N'-disuccinimidyl carbonate and an organic base, followed by an amino substituted cyclic amine derivative with the ring nitrogen protected, gives a urea derivative (path A). Cleavage of the protecting group provides an amine that can be derivatized by treatment with, for example, acyl chlorides, sulfonyl chlorides, and isocyanates. Alternatively, in the urea-forming step an amino substituted cyclic amine derivative wherein the ring nitrogen is derivatized with an R 9 substituent can be used (path B). Path B is the preferred method when R 9 is aryl or R 1 heteroaryl. Compounds of Formula I where is can be prepared by the methods outlined in Scheme 1. Scheme 2 deprotect In Scheme 2, a biaryl amine derivative is treated with triphosgene and a base followed by treatment with 4-(methylamino)cyclohexanone ethylene ketal to give a urea derivative. Deprotection of the ketal, for example, by treatment with a strong acid, gives a ketone derivative. The ketone can then be derivatized by treatment with QNH 2 . Scheme 3 * ..N H ' S N γ O In Scheme 3, an acid chloride is condensed with thiosemicarbazide to give an N-acyl thiosemicarbazide derivative. Treatment of the N-acyl thiosemicarbazide with a strong acid results in the formation of an aminothiadiazole derivative. The aminothiadiazole is converted to a substituted urea derivative as described earlier. Scheme 4 deprotect In Scheme 4 an alpha bromo acetal is condensed with thiourea to form a 5- substituted 2-aminothiazole derivative. The 2-aminothiazole derivative is converted to a substituted urea derivative as descπbed in earlier schemes. Scheme 5 In Scheme 5, a 5-halo-2-nitrothiazole derivative is coupled to an arylzinc halide under palladium catalysis to give a 2-aryl-5-nitrothiazole derivative. The 5- nitrothiazole derivative is then converted to a substituted urea derivative as described in earlier Schemes. The compounds of Formula I exhibit selective neuropeptide Y Y5 receptor antagonizing activity, which has been correlated with pharmaceutical activity for treating eating disorders, such as obesity and hyperphagia, and diabetes. The compounds of Formula I display pharmacological activity in test procedures designed to demonstrate neuropeptide Y Y5 receptor antagonist activity. The compounds are non-toxic at pharmaceutically therapeutic doses. Following are descriptions of the test procedures. cAMP Assay HEK-293 cells expressing the Y5 receptor subtype were maintained in Dulbecco's modified Eagles' media (Gico-BRL) supplemented with 10% FCS (ICN), 1% penicillin-streptomycin and 200 μg/ml Geneticin®(GibcoBRL #11811-031 ) under a humidified 5% CO 2 atmosphere. Two days prior to assay, cells were released from T- 175 tissue culture flasks using cell dissociation solution (1X; non-enzymatic [Sigma #C-5914]) and seeded into 96-well, flat-bottom tissue culture plates at a density of 15,000 to 20,000 cells per well. After approximately 48 hours, the cell monolayers were rinsed with Hank's balanced salt solution (HBSS) then preincubated with approximately 150 μl/well of assay buffer (HBSS supplemented with 4 mM MgCI 2 , 10 mM HEPES, 0.2% BSA [HH]) containing 1 mM 3-isobutyl-1-methylxanthine ([IBMX] Sigma #1-587) with or without the antagonist compound of interest at 37°C. After 20 minutes the 1 mM IBMX-HH assay buffer (± antagonist compound) was removed and replaced with assay buffer containing 1.5 μM (CHO cells) or 5 μM (HEK-293 cells) forskolin (Sigma #F-6886) and various concentrations of NPY in the presence or absence of one concentration of the antagonist compound of interest. At the end of 10 minutes, the media were removed and the cell monolayers treated with 75 μl ethanol. The tissue culture plates were agitated on a platform shaker for 15 minutes, after which the plates were transferred to a warm bath in order to evaporate the ethanol. Upon bringing all wells to dryness, the cell residues were resolubilized with 250 I FlashPlate® assay buffer. The amount of cAMP in each well was quantified using the [ 125 l]-cAMP FlashPlate® kit (NEN #SMP-001 ) and according to the protocol provided by the manufacturer. Data were expressed as either pmol cAMP/ml or as percent of control. All data points were determined in triplicate and EC 50 's (nM) were calculated using a nonlinear (sigmoidal) regression equation (GraphPad Prism™). The KB of the antagonist compound was estimated using the following formula: KB = [B} / (1 - {[A] / [A]}) where [A] is the EC 50 of the agonist (NPY) in the absence of antagonist, [A'] is the EC 50 of the agonist (NPY) in the presence of antagonist, and [B] is the concentration of the antagonist. NPY Receptor Binding Assay Human NPY Y5 receptors were expressed in CHO cells. Binding assays were performed in 50 mM HEPES, pH 7.2, 2.5 mM CaCI 2 , 1 mM MgCI 2 and 0.1 % BSA containing 5-10 μg of membrane protein and 0.1 nM 125 L-peptide YY in a total volume of 200 μl. Non-specific binding was determined in the presence of 1 μM NPY. The reaction mixtures were incubated for 90 minutes at room temperature then filtered through Millipore MAFC glass fiber filter plates which had been pre-soaked in 0.5% polyethleneimine. The filters were washed with phosphate-buffered saline, and radioactivity was measured in a Packard TopCount scintillation counter. For the compounds of this invention, a range of neuropeptide Y5 receptor binding activity of from about 0.3nM to about 1000nM was observed.
