Abstract:
Based on the study of rhodanine derivative WL-276,some novel compounds were synthesized,and their anti-tumor effects were screened by MTT method.Compounds II
1-4 were obtained by cyclization and condensation from the certain amino acids,and then coupled respectively with hydrogen sulfide donor ADT-OH to afford compounds III
1-4,whose structures were confirmed by
1H NMR,IR and HR MS.Furthermore,preliminary pharmacological results suggested that compounds II
1,3,4,III
1-4 had strong inhibitory effects on the proliferation of HepG2 and DU145 tumor cells.Particularly,the anti-proliferation activity of compounds III
2,4 on HepG2 and compounds III
1,2,4 on DU145 tumor cells was stronger than that of the positive control,5-fluorouracil.
