Novel 4-(3-nitrophenyl)pyridine and 4-(3-nitrophenyl)pyrimidine derivatives, possessing three-atom linkages between basic nitrogen and at the C-5 (or C-3) position of the pyrimidine (or pyridine) ring, were synthesized and tested for anti-anoxic (AA) activity in mice. Among them, 6-methyl-4-(3-nitrophenyl)-2-phenyl-5-(pyrrolidinomethylcarbonyl-amino)pyrimidine (10f) had the most potent AA activity (3.2 mg/kg, i.p.). Three-dimensional molecular electrostatic potentials (3D-MEP) around the nitrogeneous basic moiety of 6-methyl-5-(4-methylpiperazin-1-ylcarbonyl)-4-(3-nitrophenyl)-2-phenylpyrimidine (FK 360) and 10f were compared. The negative zone of 10f is broader and deeper and positioned somewhat differently to that of FK 360, although there is a co-occupied spacial area in part.
合成了新型的4-(3-硝基苯基)吡啶和4-(3-硝基苯基)嘧啶衍生物,这些化合物在基本氮原子和嘧啶(或吡啶)环的C-5(或C-3)位置之间具有三原子连接,并测试其在小鼠中的抗缺氧(AA)活性。其中,6-甲基-4-(3-硝基苯基)-2-苯基-5-(吡咯烷甲酰基氨基)嘧啶(10f)显示出最强的AA活性(3.2 mg/kg,腹腔注射)。比较了6-甲基-5-(4-甲基哌嗪-1-酰基)-4-(3-硝基苯基)-2-苯基嘧啶(FK 360)和10f的三维分子电势(3D-MEP)。虽然部分区域存在共同占有的空间,10f的负电区更广泛、更深,并且位置与FK 360有所不同。
