Tirapazamine (3-amino-1,2,4-benzotriazine 1,4-dioxide) is a heterocyclic di-N-oxide that undergoes enzymatic deoxygenation selectively in the oxygen-poor (hypoxic) cells found in solid tumors to generate a mono-N-oxide metabolite. This work explored the idea that the electronic changes resulting from the metabolic deoxygenation of tirapazamine analogues(More)
The title compound, C9H8N2O, crystallized with four independent mol-ecules in the asymmetric unit. The four mol-ecules are linked via one O-H⋯N and two N-H⋯N hydrogen bonds, forming a tetra-mer-like unit. In the crystal, mol-ecules are further linked by O-H⋯N and N-H⋯O hydrogen bonds forming layers parallel to (001). These layers are linked via C-H⋯O(More)
