The design of -platinum(ii) complexes marked a significant turning point in the development of unconventional anticancer metallodrugs. Compared to cisplatin, these complexes induce distinctly different cellular responses and are often active against cisplatin-resistant cell lines. In this study, we synthesized and fully characterized two new Pt(ii) complexes, introducing one acetate (OCOCH) ligand (x) into the -PtXX' axis, where X' is either acetate or chlorido. We evaluated their cytotoxicity across a panel of malignant (Capan-1, B16, MCF7, HCT-116, CT26 and P31) and non-malignant (HaCaT, HUVEC, BEC, and MCF10A) cell lines, finding that the complex with only one acetate to a chlorido group is more active and selective than the complex with two acetates (X = X'). Furthermore, the two complexes differ from cisplatin in their cellular uptake route as well as mode of action by inducing cancer cell death non-DNA-associated mechanisms.
含铂（II）配合物的设计标志着非常规抗癌金属药物研发中的一个重要转折点。与顺铂相比，这些配合物会引发明显不同的细胞反应，并且通常对顺铂耐药的细胞系具有活性。在本研究中，我们合成并全面表征了两种新的铂（II）配合物，在-PtXX'轴中引入了一个乙酸根（OCOCH）配体（x），其中X'为乙酸根或氯离子。我们评估了它们对一系列恶性（Capan-1、B16、MCF7、HCT-116、CT26和P31）和非恶性（HaCaT、HUVEC、BEC和MCF10A）细胞系的细胞毒性，发现含有一个乙酸根与一个氯离子基团的配合物比含有两个乙酸根（X = X'）的配合物更具活性和选择性。此外，这两种配合物在细胞摄取途径以及通过非DNA相关机制诱导癌细胞死亡的作用方式上与顺铂不同。
