Abstract

Benzothiazolyl thiocarbamides has been achieved using a catalytic amount of 4- dimethylaminopyridine (DMAP) followed by its chemoselective oxidative cyclization with 1, 3- di-n-butylimidazolium tribromide [bbim][Br3] to afford the N-bis-benzothiazole derivatives. All the synthesized compounds were evaluated for cytotoxic activity against two human monocytic cell lines (U 937, THP-1) and a mouse melanoma cell line (B16-F10). Based on ...
