Abstract:
A series of 2-(3-butynoicamidophenyl)benzothiazole derivatives were synthesized starting from 4-fluoro-3-nitrobenzoic acid. Structures of all the synthesized compounds were confirmed by 1H NMR and HR-MS. Their antitumor activities against human tumor cells lines (HCT116, Mia-PaCa2, U87-MG, A549, NCI-H1975) were evaluated by MTT assay. The results revealed that most of the synthesized compounds showed potent activities against HCT116, Mia-PaCa2, U87-MG tumor cells lines. Particularly, compounds 14c and 14h exhibited better activity with IC50 values of 1 x 10(-8) mol x L(-1) against U87-MG and HCT116 respectively. The structure-activity relationship of compounds was also discussed preliminarily.
