This work reports on the synthesis, characterization, and in vitro cytotoxic activity of some new platinum(II), palladium(II), and gold(III) derivatives of methylsarcosinedithiocarbamate and its S-methyl ester, to study their behavior as potential antitumor agents. The biological activity of these compounds, as determined by growth inhibition and apoptosis induction, has been investigated in both human
这项工作报告了甲基肌氨酸二硫代氨基甲酸酯及其S-甲酯的一些新的铂(II),钯(II)和金(III)衍生物的合成,表征和体外细胞毒性活性,以研究其作为潜在的抗肿瘤剂的行为。 。已通过在人类白血病早幼粒细胞HL60和人鳞状宫颈腺癌HeLa细胞系中研究了通过生长抑制和凋亡诱导确定的这些化合物的生物学活性,并将其活性与著名的铂类抗癌药进行了比较。顺铂。根据这些实验结果,[Pd(MSDT)X] n(MSDT =甲基肌氨酸二硫代氨基甲酸酯; X = Cl,Br)复合物对HL60和HeLa细胞均显示出强烈的剂量依赖性生长抑制作用,IC(50)值略有升高高于顺铂的记录;此外,[Au(MSDT)X(2)]活性明显高于或至少与参考药物相当。两种细胞系均暴露于[Pd(MSDT)X] n和[Au(MSDT)X(2)]复合物可诱导凋亡,这是通过Apo2.7分析确定的。
