In a search for new 1, 4-dihydropyridine derivatives with a long-lasting effect on the cardiovascular system, a series of piperazinylalkyl esters (I) bearing a lipophilic substituent on the 4-nitrogen of the piperazine ring was synthesized and tested for hypotensive effect in spontaneously hypertensive rats (SHR). Compounds I, especially those having a diphenylmethyl moiety on the piperazine ring, showed extremely potent and long-lasting hypotensive properties. Analogues related to I were also prepared, and the structure-activity relationships are discussed.
在寻找对心血管系统具有长效作用的新的1,4-二氢吡啶衍生物时,合成并测试了一系列在哌嗪环的4-氮上带有亲脂性取代基的吡哆酯类化合物I对自发性高血压大鼠(SHR)的降压效果。化合物I,尤其是那些在哌嗪环上有二苯甲基部分的化合物,显示出极其强大且长效的降压特性。还制备了与I相关的类似物,并讨论了结构-活性关系。
