A series of perbutyrylated glycosides of podophyllotoxin and its derivatives were synthesized and evaluated for their antitumor activity in vitro. Most of them exhibit cytotoxic activity against a panel of five human cancer cell lines (HL-60, SMMC-7721, A-549, MCF-7, SW480) using MTT assays. Among the synthesized compounds, epipodophyllotoxin alpha-D-galactopyranoside 8b, epipodophyllotoxin a-D-arabinopyranoside 8e, and podophyllotoxin beta-D-glucopyranoside 11a show the highest potency of anticancer activity with their IC50 values ranging from 0.14 to 1.69 mu M. Structure activity relationship analysis indicates that the type of glycosidic linkage, the configuration at C-4 of the podophyllotoxin scaffold, and the substitution at 4'-position (OH vs OCH3) can all have significant effect on the potency of their anticancer activity. Several compounds are more active than the control drugs Etoposide and Cisplatin, suggesting their potential as anticancer agents for further development. (C) 2015 Elsevier Ltd. All rights reserved.
