Analogues of the dibasic antiarrhythmic agent disobutamide (2) were prepared and evaluated for antiarrhythmic efficacy, myocardial depression, and anticholinergic activity. The replacement of an isopropyl group in disobutamide by an acetyl group led to the monobasic analogue SC-40230, 7a, which demonstrated good antiarrhythmic activity accompanied by less myocardial depressant and anticholinergic activities
制备了二元抗心律不齐药二丁胺(2)的类似物,并评估了抗心律不齐药的功效,心肌抑制和抗胆碱能活性。二乙酰丁酰胺中的异丙基被乙酰基取代导致一元类似物SC-40230,7a,表现出良好的抗心律失常活性,同时心肌抑制和抗胆碱能活性降低。另外,它没有像母体化合物一样引起明显的细胞质液泡。从其他类似物中选择SC-40230作为临床评估的候选物。制备和评估的其他化合物包括吲哚兹丁酮和二丁胺的仲胺异构体。
