摘要
合成并表征了乙二胺桥联2-甲基邻菲罗啉配体及其镧(Ⅲ)配合物,研究了配合物对人的HL60白血病、PC-3MIE8前列腺癌、BGC-823胃癌、MDA-MB-435乳腺癌、Bel-7402肝癌、Hela宫颈癌等6种瘤株的体外抗肿瘤活性及其与DNA的作用方式。结果表明,该化合物对实验的6种瘤株均具有明显的生长抑制作用,其作用机理可能是配合物以部分插入方式,同时伴随共价作用和静电作用与DNA发生作用,进而影响基因调控与表达,从而抑制肿瘤细胞的生长,最终导致癌细胞的死亡。
One lathanum ( Ⅲ ) complex containing 2-methyl-1, 10-phenanthroline units bridged by ethylenediamine was synthesized and characterized. The complex has been assayed for antitumor activity in vitro against HL-60 (human leukocytoma) cells, PC- 3MIE8 (human prostate carcinoma) cells, BGC-823 (human stomach carcinoma) cells, MDA-MB-435 (human galactophore carcinoma) cells, Bel-7402 (human liver carcinoma) cells, and Hela (human cervix carcinoma) cells. The results show that the complex exhibits good growth inhibition against different cell lines in general. DNA binding studies indicate that the complex possibly interacts with ctDNA by part-intercalative, covalent binding and electrostatic affection.
