A novel series of substituted diaryl imidazo[2,1-b]benzothiazole derivatives (8a-y) were synthesized by condensation reaction between 2-amino benzothiazole derivatives (3a-g) and substituted α-bromo-1, 2-(substituted) diaryl-1- ethanones (7a-i). The structures of the synthesized compounds were established by IR, 1H NMR, 13C NMR and mass spectroscopical data. The compounds (8a-y) were evaluated for their in-vitro cytotoxic activity on murine (B16F10) and human (MCF-7) cancer cells by using MTT assay. From the in vitro studies compounds 8p, 8u and 8y were found most effective with an IC50 range of 0.56 -27.50 µ M in MCF-7 and 2.57-36.54 µ M in B16F10 cells.
通过2-氨基苯并噻唑衍生物(3a-g)与取代α-溴-1,2-取代二苯基-1-乙酮(7a-i)的缩合反应,合成了一系列新型取代二苯并咪唑[2,1-b]苯并噻唑衍生物(8a-y)。通过IR、1H NMR、13C NMR和质谱数据确定了合成化合物的结构。利用MTT法评估了化合物(8a-y)对小鼠(B16F10)和人(MCF-7)癌细胞的体外细胞毒活性。从体外研究中发现,化合物8p、8u和8y最为有效,对MCF-7细胞的IC50范围为0.56-27.50 μM,对B16F10细胞的IC50范围为2.57-36.54 μM。
