Novel benzothiazole derivatives have been synthesised via the corresponding
imino-1,2,3-dithiazoles. The cytotoxicity of some of these polyheterocycli
c compounds was studied. Our results show that 2-cyano derivatives exhibit
a medium in vitro antitumour activity. (C) 1999 Editions scientifiques et m
