补充资料:密苏林
分子式:C12H14N2O2
分子量:218.26
CAS号:125-33-7
性质:白色结晶性粉末。熔点281-282℃。微溶于醇,几乎不溶于水、丙酮或苯。无臭,味微苦。
制备方法:将乙酸乙酯加入乙醇钠中,回流半小时,冷却至室温,加入乙基苯基丙二酸二乙酯及硫脲,加流9h。冷至0℃,加入乙醇,在0-5℃滴入盐酸至pH=3-3.5。加入锌粉,升温至回流,缓缓补加盐酸,保持的应液有2-3%含酸量,加毕,保温3h。趁热过滤,滤液回收乙醇。冷至20℃,加水,过滤,洗涤滤饼,得扑米酮。
用途:用于癫痫大发作和精神运动性发作。抗癫痫作用与苯巴比妥近似,但比苯巴比妥有选择性;作用强度不如苯妥英钠,但两者合用有协效应。
