Item Design, synthesis and antimycobacterial activity of novel nitrobenzamide derivatives(Elsevier, 2018) Wang, Hongjian; Lv, Kai; Li, Xiaoning; Wang, Bo; Wang, Apeng; Tao, Zeyu; Geng, Yunhe; Wang, Bin; Huang, Menghao; Liu, Mingliang; Guo, Huiyuan; Lu, Yu; Medicine, School of MedicineWe report herein the design and synthesis of a series of novel nitrobenzamide derivatives. Results reveal that many of them display considerable in vitro antitubercular activity. Four N-benzyl or N-(pyridine-2-yl)methyl 3,5-dinitrobenzamides A6, A11, C1 and C4 have not only the same excellent MIC values of <0.016 μg/mL against both drug-sensitive MTB strain H37Rv and two drug-resistant clinical isolates as PBTZ169 and the lead 1, but also acceptable safety indices (SI > 1500), opening a new direction for further development.Item Design, synthesis and antitubercular evaluation of benzothiazinones containing a piperidine moiety(Elsevier, 2018-05) Lv, Kai; Tao, Zeyu; Liu, Qian; Yang, Lu; Wang, Bin; Wu, Shuo; Wang, Apeng; Huang, Menghao; Liu, Mingliang; Lu, Yu; Medicine, School of MedicineWe 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.
