  Oxidation of 2-Deoxyribose by Benzotriazinyl Radicals of Antitumor 3-Amino-1,2,4-benzotriazine 1,4-Dioxides

  摘要：

  Tirapazamine (3-amino-1,2,4-benzotriazine 1,4-dioxide) is the lead bioreductive drug in clinical trials as an anticancer agent to kill refractory hypoxic cells of solid tumors. It has long been known that, upon metabolic one-electron reduction, tirapazamine induces lethal DNA double strand breaks in hypoxic cells. These strand breaks arise from radical damage to the ribose moiety of DNA, and in this pulse radiolysis and product analysis study we examine mechanistic aspects of the dual function of tirapazamine and analogues in producing radicals of sufficient power to oxidize 2-deoxyribose to form radicals, as well as the ability of the compounds to oxidize the resulting deoxyribose radicals to generate the strand breaks. Both the rate of oxidation of 2-deoxyribose and the radical yield increase with the one-electron reduction potentials of the putative benzotriazinyl radicals formed from the benzotriazine 1,4-dioxides. Subsequent oxidation of the 2-deoxyribose radicals by the benzotriazine 1,4-dioxides and 1-oxides proceeds through adduct formation followed by breakdown to form the radical anions of both species. The yield of the radical anions increases with increasing one-electron reduction potentials of the compounds. We have previously presented evidence that oxidizing benzotriazinyl radicals are formed following one-electron reduction of the benzotriazine 1,4-dioxides. The reactions reported in this work represent the kinetic basis of a short chain reaction leading to increased oxidation of 2-deoxyribose, a process which is dependent on the one-electron reduction potential of the benzotriazinyl radicals that are above a threshold value of ca. 1.24 V.
