tuberculosis, constitute a serious public health threat, highlighting the urgent need of novel antibacterial agents. In this work, two novel series of nicotinic acid hydrazone derivatives (6a-r) and quinolone hydrazide derivatives (12a-l) were synthesized and evaluated as antimicrobial and antitubercular agents. The synthesized compounds were evaluated in vitro for their antibacterial, antifungal and antimycobacterial
高抗性细菌菌株和结核病的发展日趋严重,构成了严重的公共卫生威胁,突出了对新型抗菌剂的迫切需求。在这项工作中,合成了两个新颖的烟酸衍生物(6a-r)和喹诺酮酰肼衍生物(12a-1),并作为抗菌剂和抗结核剂进行了评估。体外评估了合成的化合物的抗菌,抗真菌和抗分枝杆菌活性。化合物6f和6p带有3,4,5-(OCH3)3和2,5-(OCH3)2亚苄基的基团是最有效的,并且具有抗菌,抗真菌作用(MIC:0.49–1.95μg/ mL)和(MIC:0.49–0.98μg / mL)和抗分枝杆菌活性(MIC = 0.76和0.39μg/ mL)。此外,几种衍生物6e,6h,6l-6o,6q,6r,12a,12b,12e,12h,12k和12l表现出显着的抗菌和抗真菌活性,MIC值在1.95至7.81μg/ mL之间。对结核分枝杆菌有极好的活性MIC为0.39至3.12μg/ mL。此外,测试了一些最具活
