1-dioxides, most of the new compounds were found to be poorly active on B-cells but exhibited clear vasorelaxant properties. 3-(3, 3-Dimethyl-2-butylamino)-4H-pyrido[2,3-e]-1,2,4-thiadiazine 1, 1-dioxide (4d) and 7-chloro-3-(3, 3-dimethyl-2-butylamino)-4H-pyrido[2,3-e]-1,2,4-thiadiazine 1, 1-dioxide (5d), two compounds bearing the alkyl side chain of pinacidil, were found to be the most active representatives
合成了一系列与二氮嗪和吡那地尔相关的3-烷基氨基-4H-吡啶并[2,3-e] -1,2,4-噻二嗪1,1-二氧化物,并在分离条件下测试了其作为K(ATP)通道开放剂的可能性。胰腺内分泌组织以及孤立的血管,肠和子宫平滑肌。与先前描述的3-烷基氨基-4H-吡啶并[4,3-e] -1,2,4-噻二嗪1,1-二氧化物相反,发现大多数新化合物对B细胞的活性较弱,但表现出明确血管舒张特性。3-(3,3-二甲基-2-丁基氨基)-4H-吡啶并[2,3-e] -1,2,4-噻二嗪1,1-二氧化物(4d)和7-氯-3-(3,发现3-二甲基-2-丁基氨基)-4H-吡啶并[2,3-e] -1,2,4-噻二嗪1,1-二氧化物(5d)是两个带有吡那地尔烷基侧链的化合物。各自系列中大鼠主动脉环上最活跃的代表。3-环烷基烷基氨基-和3-芳烷基氨基-7-氯-4H-吡啶并[2,3-e] -1,2,4-噻二嗪1,1-二氧化物还
