substitued‐1,2,4‐triazol‐3‐yl]‐butane 13‐18 were prepared from 1,4‐bis(5[hydrazinocarbonylmethylthio]‐4‐substituted‐1,2,4‐triazol‐3‐yl) butane based derivativess were synthesized 1‐6. All the synthesized compounds were characterized by IR, NMR and Mass spectral studies. The synthesized compounds 7‐18 were screened for in‐vitro cytotoxicity potential using the standard MTT (3‐(4,5‐dimethylthiazol‐2‐yl)‐2
新系列1,4-双[5-(5-mercapto-1,3,4-oxadiazol-2-yl-methyl)-thio-4-located-1,2,4-triazol-3-yl] -丁烷 7-12 和 1,4-双 [5- (1-oxo-1- (3,5 二甲基吡唑-1-基) -甲基) -硫代-4-取代的-1,2,4-三唑- 3-基]-丁烷13-18由1,4-双(5[肼基羰基甲硫基]-4-取代-1,2,4-三唑-3-基)丁烷衍生物合成1-6。所有合成的化合物均通过红外、核磁共振和质谱研究进行表征。使用标准 MTT(3-(4,5-二甲基噻唑-2-基)-2,5-溴化二苯基四唑鎓)针对一组三种人类癌细胞系筛选合成的化合物 7-18 的体外细胞毒性潜力:肺癌 A-549、结肠癌 HT-29 和乳腺癌 MDA MB-231。通过吸收滴定法对三种有效分子进行了 DNA 结合研究。
