yclobut-1-enylamino]-3-ethyl-be nzonitrile (1), a novel, potent, and selective adenosine 5'-triphosphate-sensitive potassium (K(ATP)) channel opener with potential utility for the treatment of urge urinary incontinence (UUI). Excising the aniline-derived nitrogen atom of 1 or replacing it with an aralkyl group, led to bladder smooth muscle relaxant chemotypes 3 and 4, respectively. Prototype compounds
我们已经报道了(R)-4- [3,4-二氧-2-(1,2,2-三甲基-丙基氨基)-环丁-1-烯基氨基] -3-乙基的设计,合成和生物学表征-be nzonitrile(1),一种新颖,有效且选择性的腺苷5'-三磷酸敏感钾(K(ATP))通道开放剂,具有潜在的治疗急迫性尿失禁(UUI)的潜力。排除1的苯胺衍生氮原子或将其替换为芳烷基,分别导致膀胱平滑肌松弛剂化学型3和4。发现这些系列中的原型化合物会显着增加对纤毛毒素(IbTx)敏感的超极化电流,因此表明这些相对适度的结构修饰导致这些平滑肌松弛剂的作用机理从K(ATP)通道开放剂转变为大电导Ca2 +活化钾通道(BK(Ca))的活化剂。我们在这里报道了一系列取代的3-氨基-4-芳基-(和芳烷基-)环丁-3-烯-1,2-二酮的合成和生物学评估。
