     FIELD OF THE INVENTION  
       [0002]     The present invention relates to neuropeptide Y Y5 receptor antagonists useful in the treatment of metabolic and eating disorders, pharmaceutical compositions containing the compounds, and methods of treatment using the compounds.  
       BACKGROUND OF THE INVENTION  
       [0003]     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).  
         [0004]     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. Pat. No. 4,623,662 (antiatherosclerotic agents) and U.S. Pat. No. 4,405,644 (treatment of lipometabolism). Provisional application, U.S. Ser. No. 60/232,255 describes a class of substituted urea neuropeptide Y Y5 receptor antagonists.

         [0095]     Compounds of formula I may be produced by processes known to those skilled in the art as shown in the following reaction schemes and in the preparations and examples below.  
                         
 
         [0096]     In Scheme 1, a 4-halophenyl isocyanate is condensed with an amino substituted cyclic amine derivative to give a 4-halophenyl urea derivative. Cleavage of the cyclic amine protecting group by methods known to those skilled in the art affords a cyclic amine derivative that can be derivatized, for example by alkylation (Path 1). Coupling of the product with, for example, an arylboronic acid, under palladium catalysis (Suzuki coupling) yields a biaryl urea derivative. Alternatively, the condensation product can be arylated, for example, by use of a Suzuki coupling reaction (Path 2). When A is a protecting group, deprotection affords an amine that can be derivatized by, for example, sulfonylation, acylation or alkylation.  
                         
                         
 
         [0097]     In Scheme 2, reaction of an aryl lithium, for example, 5-thienyl lithium, with trimethylborate and coupling of the resultant boronate with a 4-haloaniline under palladium catalysis yields a biaryl amine derivative. Protection of the amine with, for example, trifluoroacetic anhydride gives a trifluoroacetamide derivative that can be halogenated with an appropriate halogenating agent, for example N-chlorosuccinimide. The protecting group can be cleaved and the resultant amine can be reacted with, for example, N,N′-disuccinimidyl carbonate and an amino substituted cyclic amine derivative, for example an amino piperidine derivative, to give a substituted urea. Cleavage of the piperidine nitrogen protecting group gives an amine that can derivatized, for example, by sulfonylation or acylation.  
                         
                         
 
         [0098]     In Scheme 3, a 4-haloaniline or 4-halonitrobenzene derivative is arylated by use of, for example, a Suzuki coupling reaction. When X is a nitro group, the nitro group is subsequently reduced to an amine. The biaryl amine derivative can be converted to an isocyanate derivative, which can be condensed with an amino substituted cyclic amine derivative (Path 3). Alternatively, condensation with an amino substituted cycloalkyl derivative affords cycloalkyl urea derivatives (Paths 4 and 5). An appropriately functionalized cycloalkyl urea derivative can be further functionalized as shown, for example, in Path 5.

Two days prior to assay, cells were released from T-175 tissue culture flasks using cell dissociation solution (1×; 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&#39;s balanced salt solution (HBSS) then preincubated with approximately 150 μl/well of assay buffer (HBSS supplemented with 4 mM MgCl 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 μl FlashPlate® assay buffer. The amount of cAMP in each well was quantified using the [ 125 I]-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 &#39;s (nM) were calculated using a nonlinear (sigmoidal) regression equation (GraphPad PrisM™). The K B  of the antagonist compound was estimated using the following formula: 
 
 K   B   =[B }/(1−{[A′]/[A]})

         [heading-0300]     Method for Screening Compound 14 of Example 14 for Y5 Antagonist Activity In Vivo  
         [0301]     Adult male Long-Evans or Sprague-Dawley rats (200-250 g, Charles River, Mass.) were maintained in individual cages at 22° C. on a 12 hr light/12 hr dark cycle with lights on at 0400. Rats had free access to food (Teklad Lab Rodent Chow, Bartonville, Ill.) and water. All studies were conducted in an AAALAC accredited facility following protocols approved by the Animal Care and Use Committee of the Schering-Plough Research Institute. The procedures were performed in accordance with the principles and guidelines established by the NIH for the care and use of laboratory animals.  
         [0302]     Rats were anesthetized by intramuscular injection of a mixture of ketamine and xylazine (100 and 10 mg/kg, respectively). A 22 gauge stainless steel cannula was stereotaxically implanted into the lateral ventricle using the following coordinates: 1 mm posterior to bregma, 1.5 mm lateral to midline, 3.6 mm ventral to dura. After a three week recovery period, all animals were tested for correct cannula placement by intracerebroventricular (icv) infusion of human NPY (0.3 nmol). Only animals demonstrating a profound feeding effect (&gt;2 g) within 60 min of the infusion were retained for the study. Four groups of twelve animals were used in each study. Each group was balanced such that the average baseline and NPY-induced food intake values were similar for each group. One group received an oral dose of vehicle while the other three groups received oral doses of the Y5 antagonist 14 one hour before icv administration of D-Trp34-NPY. D-Trp34-NPY was dissolved in 0.9% sterile saline (Sigma, St. Louis, Mo.) and were infused icv with a Hamilton infusion pump and syringe (Hamilton, Reno, Nev.) at a rate of 5 μl/min. The guide cannula remained inserted for an additional minute to prevent diffusion up the needle track. The chow-filled feeder was weighed during the infusion period and then returned to the home cage with the animal immediately following treatment. Food consumption was monitored at 60, 120 and 240 min after icv infusion of peptides. Differences in food intake between groups were determined by analysis of variance followed by Dunnett&#39;s multiple comparison test. Compound 14 (0.1, 0.3, 1, and 3 mg/kg) dose responsively inhibited D-Trp34-NPY stimulated food intake with an ID50 of 0.5 mg/kg.
