Novel pyrimidine derivatives, possessing linkages between the aryl group and the pyrimidine nucleus at the C-4 position, were prepared and tested for anti-anoxic (AA) activity in mice. Among them, 5-(4-methylpiperazin-1-ylcarbonyl)-4-(4-nitrobenzoyl)-2-phenylpyrimidine (2f, FR76659) possessed significant AA activity (10-100 mg/kg, i.p.) with low acute toxicity (LD50>1000 mg/kg, i.p.). Structure-activity relationships in regard to AA activity of this series of compounds were examined.
制备了新型嘧啶衍生物,在芳基和 C-4 位嘧啶核之间具有连接,并在小鼠中测试了其抗缺氧 (AA) 活性。其中,5-(4-甲基哌嗪-1-基羰基)-4-(4-硝基苯甲酰基)-2-苯基嘧啶(2f,FR76659)具有显着的AA活性(10-100 mg/kg,i.p.)且急性毒性低( LD50>1000 mg/kg,腹腔注射)。检查了该系列化合物的 AA 活性的构效关系。
