creation of therapeutic agents based on the related compounds that would be able to overcome drug resistance. An analysis of different aspects of their biological effects on living cells has revealed a remarkable ability of the S-modified derivatives to induce cell apoptosis and efficient cellular uptake of their fluorescein-conjugated counterpart, confirming the high anticancer potential of Pd(II) pincer
在寻找潜在的新型金属基抗肿瘤剂的过程中,基于具有 S 修饰的半胱氨酸和同型半胱氨酸残基的官能化酰胺,已制备了两个系列的非经典钯 (II) 钳形配合物,并通过 1D 和 2D NMR ( 1 H, 13 C、COSY、HMQC 或 HSQC、1 H– 13 C 和1 H– 15N HMBC)和红外光谱,在某些情况下,还有 X 射线衍射。大多数所得复合物对几种人类癌细胞系表现出高水平的细胞毒活性,包括结肠癌 (HCT116)、乳腺癌 (MCF7) 和前列腺癌 (PC3)。一些正在考虑的化合物在天然和多柔比星抗性转化的乳腺细胞 HBL100 中也有效,这表明基于能够克服耐药性的相关化合物的治疗剂的产生前景。对它们对活细胞生物影响的不同方面的分析表明,S-修饰衍生物具有显着的诱导细胞凋亡和荧光素偶联物有效细胞摄取的能力,
