A series of 3- or 4-phenyl-1,8-naphthyridine derivatives variously substituted in the positions 2, 6 and 7 were synthesized and evaluated for in vitro evaluation for their antimycobacterial activity as part of a TAACF TB screening program under the direction of the US National Institute of Health, NIAID division. Several compounds showed an interesting activity when tested at a concentration of 6.25
合成了在2、6和7位不同取代的一系列3-或4-苯基-1,8-萘啶衍生物,并按照TAACF TB筛查程序的一部分,在以下方法的指导下进行了体外评估其抗分枝杆菌活性。美国国家卫生研究院NIAID部门。当测试浓度为6.25微克/毫升的抗结核分枝杆菌H(37)Rv时,几种化合物表现出有趣的活性,特别是化合物2a,4a,d,8a,d和8i表现出的抑制百分比是91至99。这些化合物2a,8a和8d似乎具有良好的活性,最小抑制浓度(MIC)为6.25 microg / ml。根据生物学结果,在2或7位上最有效的取代基似乎是哌啶基。在杂环的2或7位上引入吗啉基会导致活性降低。还体外测试了1,8-萘啶衍生物对作为革兰氏阳性菌的金黄色葡萄球菌和作为革兰氏阴性菌的大肠埃希氏菌的抗菌活性。
