Synthesis and cytotoxic activities of novel 2-(1,5-bis(aryl) penta-1,4-dien-2-yl) benzo[d]thiazol derivatives

Novel 2-(1,5-bis(aryl)penta-1,4-dien-2-yl)benzo[d]thiazol (5a,b) and 2-(((1S,2S,E)-2-(benzo[d]thiazol-2-yl)-1,5-di-arylpent-4-en-1-yl)thio)aniline (6a,b) derivatives were obtained by addition of 2-aminobenzothiol to bis-benzylidinecyclobutanones (3a,b). The structures of the obtained compounds were characterized using the spectroscopic methods (NMR, IR, Elemental Analysis). Compounds 5a,b showed cytotoxic activities against C6 (Rat Brain tumor cells) and HeLa (human uterus carcinoma) in vitro.
