crystal X-ray crystallography studies confirm the structure of newly synthesized Schiff bases. The Schiff bases act as bidentate monobasic ligands, coordinating through deprotonated phenolic oxygen and azomethine nitrogen atoms. The free ligands and metal complexes are screened for their biopotency. Metal complexes exhibit better activity than ligands. Anticancer activity of ligands and their metal
已经制备了由4-吗啉代苯胺与取代的水杨醛缩合得到的席夫碱的金属(II)螯合物,并通过(1)NMR,IR,电子,EPR和磁测量研究对其进行了表征。配合物的类型为M(X-MPMP)2 [其中M = Cu(II),Co(II)),Zn(II)或VO(IV);MPMP = 2-[((4-吗啉代苯基亚氨基)甲基] 4-X-苯酚,X = Cl,(L1H),X = Br(L2H)]。单晶X射线晶体学研究证实了新合成的席夫碱的结构。Schiff碱充当双齿的一元配体,通过去质子化的酚氧和偶氮甲碱氮原子进行配位。筛选游离配体和金属络合物的生物效能。金属配合物表现出比配体更好的活性。在人类肝癌(HepG2)细胞中评估了配体及其金属配合物的抗癌活性。初步的生物测定表明,席夫碱及其锌络合物对人胃癌细胞系表现出抑制活性。
