  Discovery and Optimization of Benzotriazine Di-N-Oxides Targeting Replicating and Nonreplicating Mycobacterium tuberculosis

  摘要：

  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.

• Stille Coupling Reactions in the Synthesis of Hypoxia-Selective 3-Alkyl-1,2,4-Benzotriazine 1,4-Dioxide Anticancer Agents

  The introduction of a 3-alkyl substituent is a key step in the synthesis of 1,2,4-benzotriazine 1,4-dioxide hypoxia-selective anticancer agents, such as SN29751. The Stille reaction of 3-chloro-1,2,4-benzotriazine 1-oxides ( BTOs) 5 was inhibited by the presence of electron donating substituents on the benzo ring, thus limiting the range of compounds available for SAR studies. The use of 3-iodo-BTOs 8 did not provide a significant improvement in the yields of 3-ethyl-BTOs 6. Microwave-assisted Stille coupling of chlorides 5 gave dramatically improved yields, which were consistently superior to those from the corresponding iodides 8. The application of microwave-assisted synthesis extended the range of substituted BTOs available for SAR studies and provided an efficient, scalable synthesis of the investigational anticancer agent, SN29751 ( 1).

  The present invention relates to a synergetistic composition comprising one or more benzoazine-mono-N-oxides, and one or more benzoazine 1,4 dioxides for use in cancer therapy. The invention also provides a range of novel 1,2,4 benzoazine-mono-N-oxides and related analogues. These can be used as potentiators of the cytotoxicity of existing anticancer drugs and therapies for cancer treatment.
