A series of 2, 5-disubstituted 2, 3-dihydro-1, 2, 5-benzothiadiazepin-4(5H)-one 1, 1-dioxide derivatives were prepared and evaluated for the antiarrhythmic effect on ouabain-induced arrhythmias in guinea pigs. Most of the synthesized compounds showed the antiarrhythmic activity in this primary screening system. Some of the compounds with 2-(N, N-dimethylamino)ethyl, 2-(pyrrolidin-1-yl)ethyl and 2-oxo-2-(morpholin-4-yl)ethyl moieties on the 5-position of 1, 2, 5-benzothiadiazepin-4(5H)-one 1, 1-dioxide exhibited a potent antiarrhythmic activity. THe structure-activity relationship of these compounds was discussed.
制备了一系列2,5-二取代的2,3-二氢-1,2,5-苯并噻二氮杂卓-4(5H)-酮1,1-二氧化物衍生物,并评估其对豚鼠中乌阿碱诱导的心律失常的抗心律失常作用。大多数合成的化合物在此初级筛选系统中显示出抗心律失常活性。在1,2,5-苯并噻二氮杂卓-4(5H)-酮1,1-二氧化物的5位上具有2-(N,N-二甲基氨基)乙基、2-(吡咯烷-1-基)乙基和2-氧代-2-(吗啉-4-基)乙基部分的一些化合物表现出强效的抗心律失常活性。讨论了这些化合物的结构-活性关系。
