A series of imidazole-5-carboxylic acids bearing alkyl, alkenyl, and hydroxyalkyl substituents at the 4-position and their related compounds were prepared and evaluated for their antagonistic activities to the angiotensin II (AII) receptor. Among them, the 4-(1-hydroxyalkyl)-imidazole derivatives had strong binding affinity to the AII receptor and potently inhibited the AII-induced pressor response
制备了一系列在4-位带有烷基,烯基和羟烷基取代基的咪唑-5-羧酸及其相关化合物,并评估了它们对血管紧张素II(AII)受体的拮抗活性。其中,4-(1-羟烷基)-咪唑衍生物对AII受体具有很强的结合亲和力,并通过静脉内给药有效地抑制了AII诱导的升压反应。这些酸的各种酯通过口服显示出有效和持久的拮抗活性。最有前途的化合物是(5-甲基-2-氧代-1,3-二氧杂-4-基)甲基(CS-866)和4-(1-羟基-1-甲基乙基)-的(新戊酰氧基)-甲基酯2-丙基-1-[((2'-1H-四唑-5-基联苯-4-基)-甲基]咪唑-5-羧酸(26c)。
