example, N-cyano-N'-(3,5-dichlorophenyl)-N"-(3-methylbutyl)guanidine, 1, have previously been described as potassium channel openers on beta cells and smooth muscle cells. In the present study 3,3-diamino-sulfonylacrylonitrile, a new bioisostere of the cyanoguanidine group, was investigated. 3,3-Diamino-sulfonylacrylonitriles were prepared in a two step synthesis from the corresponding isothiocyanates
吡那地尔类似物,例如N-氰基-N'-(3,5-二氯苯基)-N“-(3-甲基丁基)胍1,先前已被描述为β细胞和平滑肌细胞上的钾通道开放剂。本研究研究了氰基胍基团的一种新的生物异构体3,3-二氨基磺酰基丙烯腈,由两步合成由相应的异硫氰酸盐和磺酰基乙腈制备了3,3-二氨基磺酰基丙烯腈,单晶X射线晶体学和核磁共振波谱法用于建立2-(4-氯苯基磺酰基)-3-环丁基氨基-3-(3,5-二氯苯基氨基)丙烯腈3i的结构,分析证实3i假定为交错构象,被认为是能量上最有利的。已鉴定出合成的化合物是从β细胞系和大鼠胰岛中葡萄糖刺激的胰岛素分泌的有效抑制剂,对血管平滑肌的影响极小。
