Neuropeptide Y5 receptor antagonist comprises new or known aminosulfinyl or aminosulfonyl derivatives (I). Neuropeptide Y5 receptor antagonist comprises aminosulfinyl or aminosulfonyl derivatives of formula (I), their prodrugs, salts or solvates. [Image] R 1optionally substituted lower alkyl, cycloalkyl or aryl, or R 1 + R 2lower alkylene; n : 1 or 2; X : (CR 3R 4) pA(CR 5R 6) q, HetU, NR 2X or optionally substituted lower alkylene, lower alkenylene, CO-lower alkylene or CO-lower alkenylene; A : optionally substituted cycloalkylene, cycloalkenylene, bicycloalkylene, arylene or divalent heterocycle; p, q : 0 or 1; Het : piperidinediyl, piperazinediyl, pyridinediyl, pyrazinediyl, pyrrolidinediyl or pyrrolediyl all attached to NR 2 via N; U : a bond, lower alkylene or lower alkenylene; Y : OCONR 7, CONR 7, CSNR 7, NR 7CO or NR 7CS; R 2-R 7H or lower alkyl; Z : optionally substituted lower alkyl, lower alkenyl, amino, lower alkoxy, carbocyclyl or heterocyclyl. Independent claims are also included for compounds (I), their salts, prodrugs and solvates in which: (i) X = 2-6C alkylene or 3-6C alkenylene; and R 1 = optionally substituted 3-10C alkyl or 5 or 6C cycloalkyl; provided that when Y = NR 7, the Z is not lower alkylphenylamino, lower hydroxyalkylphenylamino or acylphenylamino; (ii) A = heteroarylene or optionally substituted cycloalkylene, cycloalkenylene, bicycloalkylene or piperidinylene; and R 1 = optionally substituted 3-10C alkyl or 5 or 6C cycloalkyl; and (iii) A = p-phenylene; R 1 = 3-10C alkyl or 5 or 6C cycloalkyl and Z = p-lower alkylphenylene; provided that when R 1 = isopropyl, the Z is not p-n-butylphenylene. ACTIVITY : Anorectic; antidiabetic; hypotensive; antilipemic; antiarteriosclerotic; cardiant. MECHANISM OF ACTION : Neuropeptide-Y5 antagonist. In assays, a compound of formula (Ia) exhibited IC 50 values for neuropeptide Y5 binding of 0.1 nM and for cAMP in Chinese hamster ovary cells of 1.9 nM. [Image]. |
