Novel 4-arylazole (i.e. thiazole, oxazole, and imidazole) derivatives, possessing an amino moiety at the C-5 position of the azole ring, were prepared and tested for anti-anoxic (AA) activity in mice. Among them, 5-(4-methylpiperazin-1-yl)methyl-4-(3-nitrophenyl)-2-phenylthiazole (3b, FR75094) possessed significant AA activity (10 mg/kg, i.p. and 100 mg/kg, p.o., respectively), and was also effective on anti-lipid peroxidation (ALP) assay and inhibited arachidonate-induced cerebral edema in rats. Structure-activity relationships in regard to AA activity of this series of compounds are discussed.
新型4元氮杂环(即噻唑、噁唑和咪唑)衍生物,其氮杂环第5位具有氨基基团,被制备并用于测试对小鼠的抗缺氧(AA)活性。其中,5-(4-甲基哌嗪-1-基)甲基-4-(3-硝基苯基)-2-苯基噻唑(3b,FR75094)显示出显著的AA活性(分别为10 mg/kg腹腔注射和100 mg/kg口服),并且在抗脂质过氧化(ALP)测试中有效,抑制了花生四烯酸引起的大鼠脑水肿。讨论了这一系列化合物在AA活性方面的构效关系。
