3‐amino‐1,2,4‐benzotriazine‐1,4‐dioxide derivatives were synthesized and screened for their in vitro cytotoxicity against promyelocytic leukemia HL‐60, androgen‐independent prostate tumor PC3, hepatocellular carcinoma Bel‐7402, human esophagus tumor ECA‐109, and human breast tumor MCF‐7 cell lines in hypoxia and in normoxia. Most compounds showed higher cytotoxic activity both in hypoxia and in normoxia

Compounds bactericidal against both replicating and nonreplicating Mtb may shorten the length of TB treatment regimens by eliminating infections more rapidly. Screening of a panel of antimicrobial and anticancer drug classes that are bioreduced into cytotoxic species revealed that 1,2,4-benzotriazine di-N-oxides (BTOs) are potently bactericidal against replicating and nonreplicating Mtb. Medicinal chemistry optimization, guided by semiempirical molecular orbital calculations, identified a new lead compound (20q) from this series with an MIC of 0.31 mu g/mL against H37Rv and a cytotoxicity (CC50) against Vero cells of 25 mu g/mL. 20q also had equivalent potency against a panel of single-drug resistant strains of Mtb and remarkably selective activity for Mtb over a panel of other pathogenic bacterial strains. 20q was also negative in a L5178Y MOLY assay, indicating low potential for genetic toxicity. These data along with measurements of the physiochemical properties and pharmacokinetic profile demonstrate that BTOs have the potential to be developed into a new class of antitubercular drugs.
