Four mexiletine analogues have been tested for their antiarrhythmic, inotropic, and chronotropic effects on isolated guinea pig heart tissues and to assess calcium antagonist activity, in comparison with the parent compound mexiletine. All analogues showed from moderate to high antiarrhythmic activity. In particular, three of them (1b,c,e) were more active and potent than the reference drug, while
与母体化合物美西律相比,已测试了四种美西律类似物对离体豚鼠心脏组织的抗心律失常,正性肌力和变时性作用,并评估了钙拮抗剂的活性。所有类似物均显示出中等至较高的抗心律失常活性。特别是,它们中的三个(1b,c,e)比参考药物更具活性和效力,而仅表现出中等程度的或无负性变力和变时作用以及血管舒张活性,因此显示出很高的作用选择性。所有化合物均未显示细胞毒性,并且1b,c,d不会损害运动协调性。总而言之,这些新的类似物表现出有趣的心血管特征,值得进一步研究。
