series of 4-(substituted pyridyl)-1,4-dihydropyridine derivatives were synthesized and their hypotensive effects examined. Several compounds, 2-(N-benzyl-N-methylamino)ethyl methyl 1,4-dihydro-2,6-dimethyl-4-(3-nitro-2-pyridyl)-3,5-pyridinedicarboxylate (2b), its 4-(4-nitro-2-pyridyl) analogue (2g), 4-(3-trifluoromethyl-2-pyridyl) analogue (2c), 4-(2-trifluoromethyl-3-pyridyl) analogue (3e), 4-(4-cyano-2-pyridyl)
合成了一系列4-(取代的吡啶基)-1,4-二氢吡啶衍生物,并研究了它们的降压作用。几种化合物,2-(N-苄基-N-甲基氨基)乙基甲基1,4-二氢-2,6-二甲基-4-(3-硝基-2-吡啶基)-3,5-吡啶二甲酸(2b), 4-(4-硝基-2-吡啶基)类似物(2g),4-(3-三氟甲基-2-吡啶基)类似物(2c),4-(2-三氟甲基-3-吡啶基)类似物(3e),4-发现(4-氰基-2-吡啶基)类似物(2e),4-(2-氰基-3-吡啶基)类似物(3d)和4-(6-溴-2-吡啶基)类似物(2i)具有与尼卡地平类似的降压活动;特别是2c和3e的持续时间约为尼卡地平的两倍,而2e具有在所有合成衍生物中最有效的降压活性。
