A series of 1, 4-dihydropyridine-5-cyclic phosphonate derivatives, designed as analogues of 1, 4- dihydropyridine-3, 5-dicarboxylate calcium antagonists, was synthesized and examined for antihypertensive activity. Several compounds were proved to have activities superior or comparable to that of nifedipine in lowering blood pressure in normotensive and spontaneously hypertensive rats (SHR). Among these compounds, methyl 2, 6-dimethyl-5- (2-oxo-1, 3, 2-dioxaphosphorinan-2-yl) -4- (2-nitrophenyl) -1, 4-dihydropyridine-3-carboxylate (31, DHP-218) was approximately 7 times more active than nifedipine in SHR and was selected for further development and clinical evaluation. The structure-activity relationships are discussed.
合成了一系列1,4-二氢吡啶-5-环状磷酸酯衍生物,作为1,4-二氢吡啶-3,5-二羧酸钙拮抗剂的类似物,并对其抗高血压活性进行了检查。几种化合物在降低正常血压和自发性高血压大鼠(SHR)的血压方面被证明具有优于或可比于硝苯地平的活性。在这些化合物中,甲基2,6-二甲基-5-(2-氧-1,3,2-二氧磷烷-2-基)-4-(2-硝基苯基)-1,4-二氢吡啶-3-羧酸酯(31,DHP-218)在SHR中的活性约为硝苯地平的7倍,并被选为进一步开发和临床评估的候选化合物。讨论了结构-活性关系。
