【Abstract】 AIM A series of substituted phenyliminomethylenecoumarins derivatives was designed in order to find compounds possessing anticancer activities. METHODS Title compounds (1a～b, 2a～b and 3a～q) were synthesized and screened by several anticancer models in vitro . RESULTS Twenty one new compounds (1a～b, 2a～b and 3a～q) were synthesized and screened. Structrues of the new compunds were determined by MS, HNMR and elemental analysis. Twelve compounds (3c, 3d, 3e, 3f, 3g, 3h, 3j, 3k, 3m, 3o, 3p, 3q) showed inhibitory effects on HCT 8, KB and Bel7402 cell lines in vitro . CONCLUSION Some compounds had certain anticancer activities and were worth further studying.更多还原
