Cisplatin binding to dna
WebIt does not promote cross-linking which is the cause of the gene replication process. The cisplatin molecule binds with a protein on one side and the DNA molecule on the other. The protein is critical; it protects the cisplatin molecule from being removed by DNA repair mechanisms in the cell. WebDec 19, 2024 · DNA is believed to be the critical target of the platinum-based drugs [8,9]. The structure of these drugs can be described by a general formula, cis-[PtA2X2], where A = ammonia or amine, and X = leaving group such as halide or carboxylate. In contrast to cis-Pt(II) complexes, the trans-Pt(II) derivatives have not entered a clinical trial yet.
