    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 Medicine
    We 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.

    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 Medicine
    We 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.

    Design, synthesis and in vitro anti-Zika virus evaluation of novel Sinefungin derivatives
    (Elsevier, 2018-09) Tao, Zeyu; Cao, Ruiyuan; Yan, Yunzheng; Huang, Guocheng; Lv, Kai; Li, Wei; Geng, Yunhe; Zhao, Lei; Wang, Apeng; He, Qinhao; Yang, Jingjing; Fan, Shiyong; Huang, Menghao; Guo, Huiyuan; Zhong, Wu; Lu, Mingliang; Medicine, School of Medicine
    We report herein the design and synthesis of a series of novel Sinefungin (SIN) derivatives, based on the structures of SIN and its analogue EPZ004777. Our results reveal that target compounds 1ad-af, 1ba-bb and 1bf-bh show better activity (IC50 = 4.56–20.16 μM) than EPZ004777 (IC50 = 35.19 μM). Surprisingly, SIN was founded to be not as active (IC50 > 50 μM) as we and other research groups predicted. Interestingly, the intermediates 9a-b and 11b display potent anti-ZIKV potency (IC50 = 6.33–29.98 μM), and compound 9a also exhibits acceptable cytotoxicity (CC50 > 200 μM), suggesting their promising potential to be leads for further development.
