8-chloro-substituted 3-alkylamino/cycloalkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides is described. Their inhibitory effect on the insulin releasing process and their vasorelaxant activity was compared to that of previously reported 7-chloro-3-alkylamino/cycloalkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides. “5-Chloro” compounds were found to be essentially inactive on both the insulin-secreting and
描述了5-氯-,6-氯-和8-氯取代的3-烷基氨基/环烷基氨基-4 H -1,2,4-苯并噻二嗪1,1-二氧化物的合成。将它们对胰岛素释放过程的抑制作用及其血管舒张活性与先前报道的7-氯-3-烷基氨基/环烷基氨基-4 H -1,2,4-苯并噻二嗪1,1-二氧化物进行了比较。发现“ 5-氯”化合物对胰岛素分泌和平滑肌细胞均基本无活性。相反,发现“ 8-氯”和“ 6-氯”化合物在分泌胰岛素的细胞上具有活性,其中“ 6-氯”衍生物是最有效的药物。此外,“ 6-氯”类似物比“ 7-氯”对应物表现出更少的髓鞘松弛活性。8-氯-3-异丙基氨基-4 H-1,2,4-苯并噻二嗪1,1-二氧化物(25b)和6-氯-3-环丁基氨基-4 H -1,2,4-苯并噻二嗪1,1-二氧化物(19e)被进一步确定为K ATP通道通过对胰岛素分泌细胞进行放射性同位素测量的开环剂。同样,目前在表达人SUR1 / Kir6.2
