K(+)-channel opening activity are presented. These new series of potassium channel openers so derived are best exemplified by (+/-)-2-[2-(phenylsulfanyl)ethylidene]-1-pyridin-3-ylcyclohexan ecarbothioic acid methylamide (13d, RP 66266) and trans-(+/-)-2-[2-[(phenylsulfonyl)amino]ethyl]-1-pyridin-3- ylcyclohexanecarbothioic acid methylamide (25a, RP 66784), which have IC90 values of 3 and 0.3 nM, respectively
(+/-)-2-(氰基亚甲基)-1-吡啶-3-基环己烷甲硫基++ +酸甲酰胺(6)和反式(+/-)-2-(氰基甲基)-1-吡啶-的合成及生物活性据报道衍生自(+/-)-2-氧代-1-吡啶-3-基环己烷甲硫代甲酸甲基酰胺(4)的3-基环己烷甲硫代甲酸甲基酰胺(14)。测试化合物对钾诱导的去内皮化大鼠主动脉收缩的拮抗作用。提出了6和14修饰对体外K(+)通道开放活性的影响。如此衍生的这些新系列的钾通道开放剂最好以(+/-)-2- [2-(苯基硫烷基)亚乙基] -1-吡啶-3-基环己基硫代硫代甲酸甲酰胺(13d,RP 66266)和反式-( +/-)-2- [2-[([苯磺酰基)氨基]乙基] -1-吡啶-3-基环己烷硫代甲酸甲酰胺(25a,RP 66784),其IC90值分别为3和0.3 nM。最具活性的化合物的效力表明在额外的结合位点可能发生相互作用。本文所述的化合物是潜在的抗高血压药和抗心绞痛药。
