Cisplatin hydrolysis
WebSep 9, 2014 · Cisplatin undergoes hydrolysis within the cell producing a highly reactive charged platinum complex [Pt(NH3)2ClH2O]+. After further hydrolysis, this complex binds to DNA bases through the N7 atom (preferably guanine). This DNA cross-linkage mechanism interferes with cell division and replication.
