用途: Nicergoline is an ergot derivative used to treat senile dementia and other disorders with vascular origins.Target: Alpha-1A adrenergic receptorNicergoline acts by inhibiting the postsynaptic alpha(1)-adrenoceptors on vascular smooth muscle. This inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation. Nicergoline displaced [3H]-prazosin bound to rat forebrain membranes pretreated with chloroethylclonidine (pKi = 9.9 +/- 0.2) at concentrations 60-fold lower than in rat liver membranes (pKi = 8.1 +/- 0.2). Finally, of the nicergoline metabolites studied, lumilysergol acted as a modest alpha 1 antagonist (bromonicotinic acid was devoid of alpha 1 antagonist activity). In conclusion, nicergoline is a potent and selective alpha 1A-adrenoceptor subtype antagonist, an alpha 1-adrenoceptor subtype which is mainly represented in resistance arteries [1]. 物理化学性质: CAS号:27848-84-6 常用中文名:尼麦角林 常用英文名:Nicergoline 分子式:C24H26BrN3O3 分子量:484.385 密度:1.5±0.1 g/cm3 沸点:594.4±50.0 °C at 760 mmHg 熔点:136-138° 闪点:313.3±30.1 °C 储存条件:2-8°C |
