electrophiles (E+), such as haloacetate and haloalkyl groups, were performed to get target compounds 6a–j. Compounds were characterized by NMR, mass, IR spectra and C, H, N analyses. All compounds were evaluated for their antimicrobial and antimycobacterial activities; selected analogs were screened for their anticancer activity on 60 tumor cell lines at single dose 1.00−5 M. Unfortunately, none of the compounds
从关键中间体5-(2-苄基硫烷基-吡啶- )合成了一系列新的5-(2-苄基硫烷基-吡啶-3-基)-2-(取代)-硫烷基-1,3,4-恶二唑6a – j。 3-(基)-3 H- [1,3,4]恶二唑-2-硫酮5。进行了不同亲电子试剂(E +)的亲核取代反应,例如卤代乙酸酯和卤代烷基,从而得到目标化合物6a – j。通过NMR,质谱,IR光谱和C,H,N分析来表征化合物。对所有化合物的抗微生物和抗分枝杆菌活性进行了评估。筛选选定的类似物以单剂量1.00 -5对60种肿瘤细胞系的抗癌活性 M.不幸的是,没有一种化合物对60种人类肿瘤细胞系显示出显着的抗肿瘤活性。然而,与氨苄西林相比,具有苯并噻唑部分(分别为12.5和25μg/ ml)的化合物6g和6f对大肠杆菌表现出令人鼓舞的活性。与利福平相比,分别带有三唑和吗啉的化合物6d,6j显示出有希望的抗结核活性(25μg/ ml)。
