Abstract

Abstract Sixteen flavonoid triazolyl glycosides 4–19 were synthesized in good yields via Cu(I)-catalyzed azide-alkyne cycloadditions of terminal alkynes of flavonoids 1–3 with acetylated sugar azides followed by deacetylation with sodium methoxide in anhydrous methanol. The antiproliferative activity of the synthesized compounds against three human cancer cell lines (Hela, HCC1954 and SK-OV-3) in vitro was evaluated. Flavonoids 1, 2 and flavonoid triazolyl glycosides 7, 12, 17 exhibit potent antiproliferative activity against these cancer cell lines.
