Abstract

Tirapazamine (1) is a promising antitumor agent that selectively causes DNA damage in hypoxic tumor cells, following one-electron bioreductive activation. Surprisingly, after more than 10 years of study, the products arising from bioreductive metabolism of tirapazamine have not been completely characterized. The two previously characterized metabolites are 3- amino-1, 2, 4-benzotriazine 1-oxide (3) and 3-amino-1, 2, 4-benzotriazine (5). In this work, ...
