<p>Aminopyrrole derivatives (I) are new. Aminopyrrole derivatives of formula (I) and their salts are new. R12 : H, linear or branched 1-8C alkyl, 2-8C alkene, 1-8C acyl or 1-8C alkylsulfonyl; either R1-R5 : H, halo, linear or branched 1-8C alkyl, 2-8C alkene, linear or branched 1-8C alkoxy, 3-6C alkoxy, 5-6C bicycloalkyl, polyether chain, 1-5C perfluoroalkyl, 1-8C acyl, OH, SH, primary-, secondary- or tertiary-amine, CN, CO 2H or CO 2R1a; or R1R2, R2R3, R4R3, R4R5 : 4-6C ring; R1a : linear or branched 1-8C alkyl or 3-6C cycloalkyl; R6-R11 : H, linear or branched 1-8C alkyl, 2-8C alkene, 3-6C cycloalkyl or 1-5C perfluoroalkyl; n : 1 or 2; and R13 : H or CH 3. Provided that (I) excludes: R10, R11 is CH 3or H, and then R1 or R5 is cyclopropyl or H; R8, R9 is CH 3or H, and then R1 or R5 is cyclopropyl or H; R10, R11 is CH 3or H, and then R1 or R5 is Cl or H; and #R10, R11 is CH 3or H, then R1 or R5 is Cl or H and R3 is I. [Image] ACTIVITY : Analgesic; Antianginal; Hypotensive; Metabolic; Antidiabetic; Antiarteriosclerotic; Cardiant; Vasotropic; Nephrotropic; Anorectic. MECHANISM OF ACTION : Alpha-2 adrenergic receptor modulator. The alpha -2 adrenergic receptor modulating activity of (I) was tested using competition assay. The result showed that (3-chloro-2-methyl-phenyl)-(4-methyl-4,5-dihydro-3H-pyrrol-2-yl)-amine exhibited an inhibition constant (Ki) value of greater than 10 -> 5>mu m.</p> |
