treatment for MDR-TB requires medications for a long duration (up to 20–24 months) with second-line drugs resulting in unfavorable outcomes. Nitroimidazoles are promising antimycobacterial agents known to inhibit both aerobic and anaerobic mycobacterial activity. Delamanid and pretomanid are two nitroimidazoles approved by the regulatory agencies for MDR-TB treatment. However, both agents possess unsatisfactory
耐多药肺结核(MDR-TB)是世界范围内的主要健康问题。耐多药结核病的治疗需要长期(长达 20-24 个月)的二线药物治疗,导致不良结果。硝基
咪唑类是有前途的抗分枝杆菌剂,已知可抑制需氧和厌氧分枝杆菌的活性。Delamanid 和 pretomanid 是监管机构批准用于耐多药结核病治疗的两种硝基
咪唑。然而,这两种药物的吸收和 QTc 延长都不令人满意。在寻找更安全的硝基
咪唑时,我们发现了 JBD0131 ( 2 )。它在体外和体内对M. tuberculosis H37Rv表现出优异的抗分枝杆菌活性,改善 PK 和吸收,降低 delamanid 的 QT 延长潜力。JBD0131目前正在中国进行肺结核的临床开发(CTR20202308)。
