4-dihydro-6-nitro-4-oxo-7-(substitute d secondary amino)-1,8-naphthyridine-3-carboxylic acids were synthesized and evaluated for antimycobacterial in vitro and in vivo against Mycobacterium tuberculosis H37Rv (MTB), multi-drug-resistant Mycobacterium tuberculosis (MDR-TB) and Mycobacterium smegmatis (MC2) and also tested for the ability to inhibit the supercoiling activity of DNA gyrase from M. smegmatis
51个1-(环丙基/叔丁基/ 4-氟苯基)-1,4-二氢-6-硝基-4-氧代-7-(取代仲氨基)-1,8-萘啶-3-羧酸合成并评估了对结核分枝杆菌H37Rv(MTB),耐多药结核分枝杆菌(MDR-TB)和耻垢分枝杆菌(MC2)的体外和体内抗分枝杆菌的作用,还测试了其抑制DNA超螺旋活性的能力耻垢分枝杆菌的促旋酶。在合成的化合物中,1-叔丁基-1,4-二氢-7-(4,4-二甲基恶唑烷-3-基)-6-硝基-4-氧代-1,8-萘吡啶-3-羧酸(10q)被发现是体外活性最高的化合物,对MTB和MDR-TB的MIC为0.1 microM,分别比异烟肼对MTB和MDR-TB的效力分别高3倍和455倍。
