Abstract
Novel 2-amino-4-(aminomethyl)thiazole derivatives were designed and synthesized by a facile method including the Hantzsch construction of thiazole core followed by amidation and nucleophilic substitution steps. Bioassay results showed that 4-(tert-butyl)-N-[4-(piperazin-1-ylmethyl)thiazol-2-yl]-benzamide and 4-(tert-butyl)-N-{4-[(4-piperidinopiperidin-1-yl)methyl]thiazol-2-yl}benzamide possessed similar activities compared with 5-fluorouracil. The 4-piperidino-piperidin-1-yl-containing derivative also suppressed proliferation of cultured tumor cells by inducing apoptosis.
