摘要 | Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction was employed successfully to prepare a series 4 beta-triazole-linked picropodophyllotoxin glycoconjugates (25 - 34). Maltose residue, 1,6-beta-D-diglucose residue, and several triazole-linked disaccharide and trisaccharide residues were coupled to 4 beta-azido-podophyllotoxin derivatives through click glycosylation strategy. The initial click glycosylation products were treated with catalytic amount of NaOCH3 to facilitate global deacylation and epimerization at C-2 position to yield the cis-gamma-lactone moiety in the picropodophyllotoxin glycoconjugates. Most of these picropodophyllotoxin glycoconjugates show weak cytotoxicity (IC50 > 40 mu M) against a panel of five human cancer cell lines (HL-60, SMMC-7721, A-549, MCF-7, SW480) as indicated by in vitro MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay. However, compound 27 that contains a 1,6-beta-D-di-glucose residue displays strong anticancer activity against all cancer cell lines tested, with IC50 values ranging from 0.67 to 7.41 mu M, which is significantly more potent than the control drug etoposide against four of the five cancer cells tested. Structure activity relationship analysis suggests that the 4'-O-methyl group on the E ring of podophyllotoxin scaffold is perhaps important for the anticancer activity of glycosylated picropodophyllotoxin derivatives with a cis-g-lactone moiety. |
