WebJun 17, 1999 · The anticancer activity of cis-diamminedichloroplatinum(II) (cisplatin) arises from its ability to damage DNA, with the major adducts formed being intrastrand d(GpG) and d(ApG) crosslinks. These crosslinks bend and unwind the duplex, and the altered structure attracts high-mobility-group domain (HMG … WebCisplatin binds to DNA primarily by coordination to the nitrogen (N7) atom of guanine, whereas it also can bind (to a lesser degree) to N7 and N1 of adenine and N3 of cytosine [2, 6] (Figure 7.24).

WebApr 10, 2024 · However, as for the analogous polynuclear Pt (II) chelates, these agents, containing more than one metal center, can bind to the DNA’s helix at more than one site and through long-range interstrand adducts, which prompts more severe and unrepairable damage compared to conventional, mononuclear Pt (II) drugs. WebAug 5, 2014 · Many components of the cell, including lipids, proteins and both nuclear and mitochondrial DNA, are vulnerable to deleterious modifications caused by reactive oxygen species. If not repaired, oxidative DNA damage can lead to disease-causing mutations, such as in cancer. Base excision repair and nucleotide excision repair are the two DNA repair … rowlands pharmacy s11

Uracil Flag for Review POVIDES < Back to … Web1 day ago · Platinum agents, such as cisplatin (CDDP), carboplatin, and oxaliplatin are widely used in the treatment of solid tumors [28]. Goodspeed and colleagues [29] identified the MMR as comprising the top resistant genes to cisplatin-based therapy. Cytotoxicity induced by cisplatin is achieved in an MMR-dependent manner. WebCisplatin binds to two adjacent guanines, called crosslinking, at the N7 position. [1] Cisplatin’s ability to bind to adjacent guanines arises from its cis structure, as the cis chlorines can be exchanged for water molecules … rowlands pharmacy rydings hall
