Prodrugs oxidative bioactivations

The following examples illustrate the bioprecursor-prodrug approach, although the intentional use of bioprecursor design is relatively recent and, in some cases, there are some doubts about the prospective or the retrospective character of the design. The hrst examples relate to oxidative bioactivations they are followed by examples of reductive bioactivations and dually by non-redox reactions. Often, however, the active species results from a cascade of metabolic reactions involving oxidative as well as reductive processes, complicated by hydrolytic reactions or hydration-dehydration sequences.
