A series of phosphonate derivatives, designed as analogues of 1, 4-dihydropyridine-3, 5- dicarboxylates in which a phosphonate group was introduced instead of the carboxylate group at the 5-position, was synthesized, and their antihypertensive activities were examined. Among the compounds examined, 5-diallyloxyphosphinyl-1, 4-dihydropyridine-3-carboxylates were most effective in lowering the blood pressure in normotensive rats and spontaneously hypertensive rats (SHR). The phosphonate derivatives are considered to be close analogues of the carboxylate derivatives. The structure-activity relationships are discussed.
一系列膦酸盐衍生物被设计为1,4-二氢吡啶-3,5-二羧酸盐的类似物,其中在5-位引入了膦酸基团而非羧酸基团,这些化合物被合成并检测了它们的降血压活性。在所研究的化合物中,5-二烯丙氧基膦基-1,4-二氢吡啶-3-羧酸盐在降低正常血压大鼠和自发性高血压大鼠(SHR)的血压方面最为有效。这些膦酸盐衍生物被认为是羧酸盐衍生物的近似类似物。结构-活性关系在此进行了讨论。
