摘要
模拟铜一锌超氧化物歧化酶(Cu,Zn-SOD)的活性中心,以二(2-苯并咪唑)丙烷(tbz)为桥、二(2-苯并咪唑亚甲基)胺(N3)、二(2-苯并咪唑亚甲基)甲胺(MN3)及二(2-苯并咪唑亚甲基)苄胺(BN3)为配体合成了3种异双核的小分子模型化合物,并进行了紫外、红外表征及元素分析,推测了可能的结构。采用邻苯三酚自氧化法测定了它们的生物活性,结果表明所合成的配合物具有一定的拟SOD活性。
Three kinds of small molecular copper and zinc superoxide dismutase mimics were synthesized with N, N-bis (benzimidazol-2-ylmethyl) amine (N3), N, N-bis (benzimidazol-2-ylmethyl) methylamine(MN3) and N,N-bis(benzimidazol-2-ylmethyl) benzylamine(BN3) as ligands. The complexes were characterized by UV, IR and element analysis and the structures were proposed. The biological activities were determined by means of pyrogallol autoxidation. The results showed that these complexes had SOD activities.
