补充资料:(3-二甲氨基甲酰氧苯基)三甲基铵溴化物
分子式:C12H19BrN2O2
分子量:303.21
CAS号:114-80-7

性质:白色结晶性粉末。熔点167℃(分解)。易溶于水(1g该品溶于1ml水)、乙醇、氯仿、几乎不溶于乙醚。无臭,无苦。

制备方法:间二甲氨基酚(见15070)与二甲氨基甲酰氯经酯化得到新斯的明盐基,再用溴甲烷进行成季铵盐反应制得溴新斯的明。如将新斯的明盐基与硫酸二甲酯进行成季铵盐反应,则制得新斯的明甲基硫酸盐([51-60-5])。

用途:该品具有可逆性胆碱酯酶抑制作用,致使乙酰胆碱不致酶解,长时间存在于胆碱能神经末梢,有兴奋平滑机、骨骼肌的作用;对骨骼肌的作用较强,缩瞳力较小;多用于重症肌无力、手术后腹胀与尿潴留,亦可用于室上性阵发性心动过速,以及筒箭毒碱等过量时的解毒。新斯的明甲基硫酸盐供注射用。
