用途: Nicorandil is potassium channel activator.Target: Potassium ChannelNicorandil is a vasodilatory drug used to treat angina. Nicorandil stimulates guanylate cyclase to increase formation of cyclic GMP (cGMP). cGMP activates protein kinase G (PKG) which phosphorylates and inhibits GTPase RhoA and decreases Rho-kinase activity. Reduced Rho-kinase activity permits an increase in myosin phosphatase activity, decreasing the calcium sensitivity of the smooth muscle. PKG also activates the sarcolemma calcium pump to remove activating calcium. PKG acts on K+ channels to promote K+ efflux and the ensuing hyperpolarization inhibits voltage-gated calcium channels. Overall, this leads to relaxation of the smooth muscle and coronary vasodilation [1, 2]. 物理化学性质: CAS号:65141-46-0 常用中文名:尼可地尔 常用英文名:Nicorandil 分子式:C8H9N3O4 分子量:211.175 密度:1.3±0.1 g/cm3 沸点:456.7±25.0 °C at 760 mmHg 熔点:92ºC 闪点:230.0±23.2 °C 储存条件:2-8°C |
