Design, synthesis and antitubercular evaluation of benzothiazinones containing a piperidine moiety. European Journal of Medicinal Chemistry, 151, 1–8. https://doi.org/10.1016/j.ejmech.2018.03.060https://hdl.handle.net/1805/15884We herein report the design and synthesis of benzothiazinones containing a piperidine moiety as new antitubercular agents based on the structure feature of IMB-ZR-1 discovered in our lab. Some of them were found to have good in vitro activity (MIC < 1 μg/mL) against drug-susceptible Mycobacterium tuberculosis H37RV strain. After two set of modifications, compound 2i were found to display comparable in vitro anti-TB activity (MIC < 0.016 μg/mL) to PBTZ169 against drug-sensitive and resistant mycobacterium tuberculosis strains. Compound 2i also showed acceptable PK profiles. Studies to determine PK profiles in lung and in vivo efficacy of 2i are currently under way.enPublisher PolicybenzothiaziononesPBTZ169antimycobacterial activityDesign, synthesis and antitubercular evaluation of benzothiazinones containing a piperidine moietyArticle
