英文名称：Quinidine hydrochloride 中文名称：奎尼丁盐酸盐 CAS：6151-40-2 分子式：C20H24N2O2·HCl·H2O 分子量：378.89 产品说明：Quinidine is an optical isomer of quinine, extracted from the bark of the Cinchona tree and similar plant species. It prolongs cellular action potential and decreases automaticity. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.
