3-dinitrooxy-2-propyl)], 5-methyl (ethyl or propyl) 1,4-dihydro-2,6-dimethyl-4-(1-methyl-5-nitro-2-imidazolyl)-3,5-pyridinedicarboxylates (18-29) were synthesized using modified Hantzsch reaction that involved the condensation of 2-nitrooxyethyl (8), 3-nitrooxypropyl (9), 4-nitrooxybutyl (10) or 1,3-dinitrooxy-2-propyl (13) acetoacetate with methyl (14), ethyl (15) or isopropyl (16) 3-aminocrotonate and 1-methyl-5-n
外消旋的3-[(2-硝基氧乙基),(3-硝基氧丙基),(4-硝基氧丁基)或(1,3-二硝基氧-2-丙基)],5-甲基(乙基或丙基)1,4-使用修饰的Hantzsch反应合成了二氢-2,6-二甲基-4-(1-甲基-5-硝基-2-咪唑基)-3,5-吡啶二羧酸酯(18-29),该反应涉及2-硝基氧乙基(8 ),3-硝基氧丙基(9),4-硝基氧丁基(10)或1,3-二硝基氧-2-丙基(13)乙酰乙酸与甲基(14),乙基(15)或异丙基(16)3-氨基巴豆酸酯和1-甲基-5-硝基咪唑-2-甲醛(17)。使用豚鼠回肠纵向平滑肌测定法测定体外钙通道拮抗剂活性。相对于参比硝苯地平(IC50 = 1.07 +/- 0.12 x 10(-11)M),化合物18-29表现出优越的或等效的钙拮抗剂活性(IC50 = 10(11)-10(-13)M范围) ),
