摘要:
Guanidine compounds (I), their enantiomers, diastereomers and/or tautomers and salts are new. Guanidine compounds of formula (I), their enantiomers, diastereomers and/or tautomers and salts are new. Q-N(R 2>;)-C(=NR 3>;)-N(R 1>;)-Z-W (I) W : substituted phenyl or thienyl; Z : -(CR 1>; zR 2>; z) a-(V z) b-(CR 3>; zR 4>; z) c-; a and c : 0-4; b : 0 or 1, and the sum of a, b and c = 1-5; R 1>; z to R 4>; z : hydrogen, halo, hydroxy, 1-6C alkyl, 2-6C alkenyl or alkynyl, 1-6C alkylene(3-7C)cycloalkyl, 3-7C cycloalkyl, (hetero)aryl, 1-4C alkylene(hetero)aryl or R 1>; z/R 2>; z and/or R 3>; z/R 4>; z together complete a 3-7 membered, optionally substituted, (un)saturated carbo- or heterocyclic group, containing up to 3 heteroatoms (O, N or S); V z : CO, CONR 5>; z, NR 5>; zCO, O, S, SO, SO 2, SO 2NR 5>; z, NR 5>; zSO 2, CS, CSNR 5>; z, NR 5>; zCS, CSO, OCS, COO, OCO, O, ethylnylene, C(=CR 6>; zR 7>; z), CR 6>; z=CR 7>; z, NR 5>; zCONR 5>;, OCONR 5>; z or NR 5>; z; R 1>;-R 3>; : hydrogen or substituents; Q : disubstituted 5-membered heteroaryl. Full definitions are given in the DEFINITIONS (Full Definitions) field. ACTIVITY : Antimigraine; Neuroprotective; Nootropic; Cerebroprotective; Anticonvulsant; Neuroleptic; Tranquilizer; Antidepressant; Cytostatic; Analgesic; Antialcoholic. No details of tests for these activities are given. MECHANISM OF ACTION : 5-Hydroxytryptamine (5HT) class 5 receptor non-competitive inhibitor. (I) bind to 5-hydroxytryptamine (5HT) class 5 receptors as non-competitive inhibitors, so cause (ultimately) an increase in intracellular calcium ion concentration. The compound N-(2-methoxybenzyl)-N'-(1,3-thiazol-2-yl)guanidine (Ia) had binding affinity (inhibition constant) for human 5-HT 5 receptors of below 50 nM.
