Abstract

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 μM in MCF-7 and 2.57-36.54 μM in B16F10 cells.
