complexes (saldach = N,N′-bis-(salicylidene)-R,R-1,2-diaminocyclohexane; X = Cl, PF6, BF4) as anticancer agents. The in vitro cytotoxicity activity of new cis-Pd(II) complexes against human breast adenocarcinoma cell lines (MCF-7) revealed higher growth-inhibitory effect than the native ligands. They induced a significant decrease for the protein HER2/neu expression with p
摘要 HER2/neu 因其预后相关性和预测耐药性的推定作用,已在乳腺肿瘤积极化疗的选择中显示出潜在作用。此外,抑制 DNA 复制已成为治疗癌症患者的有吸引力的策略。在此尝试中,本研究旨在制备新系列的双咪唑基盐酸盐 H2(Et)2saldach (nBu-Im+-X–)2} 及其顺式 Pd(II) 配合物(saldach = N,N '-bis-(salicylidene)-R,R-1,2-二氨基环己烷;X = Cl, PF6, BF4) 作为抗癌剂。新的 cis-Pd(II) 复合物对人乳腺腺癌细胞系 (MCF-7) 的体外细胞毒性活性显示出比天然配体更高的生长抑制作用。他们诱导蛋白质 HER2/neu 表达显着降低,p
