A series of Pt(II) complexes with nitrogen, sulfur, and oxygen donors were synthesized and evaluated for their anticancer activity. The theoretical calculations supported the experimental findings, and various techniques were used to analyze the binding modes and binding aptitude of the complexes. The results showed that these complexes exhibited in vitro anticancer activity against breast cancer cells and induced cell death through ROS generation.
A series of Pt(II) complexes [Pt(PEA)Cl-2], Ptl; [Pt(PEA)(OH2)(2)](NO3)(2), Pt2; [Pt(PEA)(LC)(+) Pt3; [Pt(PEA) (NAC)] Pt4; [Pt(PEA)(CBDCA)] Pt5, and [Pt(PEA)(ox)] Pt6 with nitrogen, sulfur, and oxygen donors (where, PEA = 2-pyridylethylamine, LC = L-cysteine and NAC = N-acetyl-L-cysteine, CBDCA(2-) = cyclobutyl-1,1-dicarboxylate, ox(2-) = oxalate) have been synthesized and spectroscopically characterized for evaluation of their bioactivity like; anticancer property. A computational DFT study endorses the theoretical support to the experimental findings. Gel electrophoresis, DNA, BSA binding, viscosity measurements, and molecular docking of the complexes have been performed to evaluate their binding modes and binding aptitude. In vitro anticancer activity has been screened for Pt1 - Pt6 on human breast carcinomas MCF-7 and MDA-MB-231 against the globally acknowledged anticancer drugs. Cell cycle progression has been analyzed with MCF-7 cell lines to observe the probable death mechanism, and toxicity of the complexes has been measured by ROS generation on MCF-7 cell lines.
