Cyanomidines. II. Synthesis and Pharmacological Activity of N-Arylalkyl-N'-cyano-3-pyridinecarboxamidines.
摘要:
合成了一系列新的氰醇胺,N-芳基烷基-N'-氰基-3-吡啶甲酰胺,并评估其对40 mM KCl诱导的收缩和去甲肾上腺素(NE)诱导的收缩对大鼠主动脉条的抑制作用。N-苯乙基氰醇胺4c表现出强效的血管舒张作用。随后,以4c作为先导化合物的体外筛选程序发现了高度有效的N-[2-(2-氯苯基)乙基]-N'-氰基-3-吡啶甲酰胺(5j)。化合物5j在氰醇胺系列中诱导了86Rb+外流的最大增加。随后对5j的吡啶环进行了修饰,并评估其静脉注射和口服降压活性。在吡啶环的5位引入氨基,得到新的钾通道开放剂5-氨基-N-[2-(2-氯苯基)乙基]-N'-氰基-3-吡啶甲酰胺(9e;KRN4884),其显示出强效的降压活性,并在口服给药后具有较长的降压作用时间。KRN4884正在进一步开发作为降压药。
