Disubstituted 1,2,4-triazoles 3a–k, 4a–k, and 6a–k have been synthesized from anthranilic acid and nicotinic acid, respectively, through a multi-step reaction sequence via their hydrazides. Synthesized compounds were evaluated for their in vitro antimicrobial activity against two gram-positive bacteria (S. aureus and B. subtilis), three gram-negative bacteria (E. coli, S. typhi, and K. pneumonia) as
双取代的1,2,4-三唑3a - k,4a - k和6a - k分别由邻氨基苯甲酸和烟酸通过酰肼经多步反应序列合成。评价了合成的化合物对两种革兰氏阳性细菌(金黄色葡萄球菌和枯草芽孢杆菌),三种革兰氏阴性细菌(大肠杆菌,伤寒沙门氏菌和肺炎克雷伯氏菌)以及四种真菌的体外抗菌活性。(黑曲霉,烟曲霉,黄曲霉和白色念珠菌)。为了探索计算方法,利用合成的化合物及其各自的生物活性定量值,统计地产生了结构-活性关系。这些模型将来可用于预测对相似类别化合物的抗菌活性。
