A new series of new diphenylamine containing 1,2,4-triazoles were synthesized from 4-arylideneamino-5-[2-(2,6-dichlorophenylamino) benzyl]-2H-1,2,4-triazole-3(4H)-thiones 3a–f. The synthesized compounds were screened for in-vitro antimycobacterial and antibacterial activities. The synthesized compounds 4a, 4e and 4d have shown potential activity against Mycobacterium tuberculosis H37Rv strain with
由4-亚芳基氨基-5- [2-(2,6-二氯苯基氨基)苄基] -2H-1,2,4-三唑-3(4H)合成了一系列新的含1,2,4-三唑的新二苯胺-硫酮3a – f。筛选合成的化合物的体外抗分枝杆菌和抗菌活性。合成的化合物4a,4e和4d已经显示出针对分别为0.2、1.6和3.125μM的MIC的结核分枝杆菌H 37 Rv菌株的潜在活性。为了更详细地研究含1,2,4-三唑衍生物的二苯胺的SAR,CoMFA(q 2 -0.432,r2 -0.902)和CoMSIA(q 2 -0.511,- [R 2 -0.953)上的模型中号。建立了结核病H 37 Rv。生成的3D-QSAR模型在外部进行了验证,并显示出显着的统计结果,这些模型可用于进一步合理设计含有1,2,4-三唑类作为有效抗结核药的新型二苯胺。
