Structural optimization of the previously identified 4-(adamantan-1-yl)-2-quinolinecarbohydrazide (AQCH, MIC=6.25 microg/mL, 99% inhibition, Mycobacterium tuberculosis H37Rv) has led to two series of 4-(adamantan-1-yl)-2-substituted quinolines (Series 1-2). All new derivatives were evaluated in vitro for antimycobacterial activities against drug-sensitive M. tuberculosis H37Rv strain. Several 4-ad
先前确定的4-(金刚烷-1-基)-2-喹啉碳酰肼(AQCH,MIC = 6.25 microg / mL,99%抑制,结核分枝杆菌H37Rv)的结构优化已导致两个系列的4-(金刚烷-1-烷基)-2-取代的喹啉(1-2系列)。在体外评估了所有新衍生物对药物敏感性结核分枝杆菌H37Rv菌株的抗分枝杆菌活性。本文所述的几种4-金刚烷-1-基-喹啉-2-羧酸N'-烷基酰肼(系列1)显示出有希望的抑制活性。特别是,类似物7、9、20和21的MIC为3.125微克/毫升。通过与各种脂族,芳族和杂芳族醛的反应对AQCH进行进一步研究,导致合成了4-金刚烷-1-基-喹啉-2-羧酸亚烷基酰肼(系列2)。类似物42-44和48在3.125 microg / mL处产生了对药物敏感的结核分枝杆菌H37Rv菌株的有希望的抗分枝杆菌活性(99%抑制)。该系列中最有效的类似物35对1.00克/毫升的药物敏感性菌株产生
