制备方法
方法1
往10g(0.035mo1)吩噻嗪-2-氨基甲酸乙酯溶于30ml无水甲苯的溶液中,滴加5.3g(0.042mo1)3-氯丙酰氯,在110~120℃回流4h,加入活性炭进行热过滤,然后冷却至室温。过滤析出的沉淀,得10.2g 10-(3-氯丙酰基)吩噻嗪-2-氨基甲酸乙酯,收率77.5%,熔点169-170℃。10.2g上面得到的酯化合物溶于50ml甲苯,加入4.72g吗啉,在110~120℃回流3h。过滤除去沉淀出的吗啉盐酸盐,滤液用水洗以除去过剩的吗啉,然后用稀盐酸酸化至Ph值为3。分出酸性水层,用活性炭处理后,再碱化至Ph值为8-9。即得莫雷西嗪,熔点156-157℃。
上面得到的莫雷西嗪用甲苯萃取,萃取液用无水硫酸镁干燥。往该无水甲苯溶液中,加入氯化氢的无水乙醚溶液,直至盐酸莫瑞西嗪完全沉淀出来。该沉淀用二氯甲烷重结晶,得9.35g盐酸莫雷西嗪,收率76.2%,熔点189℃(分解)。

生物活性
Moricizine (Moracizine) 是吩噻嗪衍生物,可以抑制跨心肌细胞膜的快速内向钠电流 (INa)。Moricizine 是一种抗心律不齐的药物,具有用于室性心动过速的潜力。体外研究
Moricizine (Moracizine) induces the tonic block of INa with the apparent dissociation constant (Kd,app) of 6.3 microM at -100 mV and 99.3 microM at -140 mV. Moricizine at 30 microM shifts the h infinity curve to the hyperpolarizing direction by 8.6 +/- 2.4 mV. Moricizine also produces the phasic block of INa, which is enhanced with the increase in the duration of train pulses, and is more prominent with a holding potential (HP) of -100 mV than with an HP of -140 mV. Moricizine exerts an antiarrhythmic action on atrial myocytes, as well as on ventricular myocytes, by blocking Na+ channels with a high affinity to the inactivated state and a slow dissociation kinetics.
