A series of new emodin derivatives modified at the C-3 and the C-6 positions were synthesized, and evaluated for their anticancer activities in vitro and in vivo. Among them, Compounds 5g and 5h had more significant antiproliferative ability against HepG2, BGC-823, AGS cancer cell lines and low cytotoxicity to HELF normal cell line, respectively. Compounds 5g and 5h induced AGS cell cycle arrest at G0/G1 phase and induce apoptosis via activation of caspase-3 and caspase-9 enzyme. In vivo studies using H22 xenografts in Kunming mice were conducted with 5g and 5h. The results revealed that the medium dosage group (10 mg/kg) of 5g and the high dosage group (25 mg/kg) of 5h showed significant antitumor activity compared to the control group.
