othioamid+ ++ e 1-oxide (8a, RP 49356) and analogues is reported. These compounds constitute a new structural class of K(+)-channel opener. The effects of changes in pyridyl group, thioamide, and thiane ring on in vitro K(+)-channel opening reactivity are discussed. A 3-pyridyl or 3-quinolyl group, a small N-alkyl thioamide function, and a thiane oxide ring, in which the sulfoxide is in a trans relationship
报道了反式-(+-)-N-甲基-2-(3-吡啶基)-2-四氢硫代吡喃氨基甲磺酰胺+++ e 1-氧化物(8a,RP 49356)和类似物的合成和生物活性。这些化合物构成K(+)通道开放剂的新结构类。讨论了吡啶基,硫代酰胺和硫杂环上的变化对体外K(+)通道开放反应性的影响。为了活性,优选3-吡啶基或3-喹啉基,小的N-烷基硫代酰胺官能团和氧化亚砜环,其中亚砜与硫代酰胺具有反式关系。选择的化合物在降压麻醉的大鼠中静脉内测试降压作用,其活性反映了其体外K(+)通道的开放活性。
