Eight novel quercetin conjugates 20~27 were successfully synthesized through a concise procedure with 15%~46% overall yields by using Rutin as the starting material.After O-benzylation,glycoside hydrolysis and O-propargylation,rutin was converted to the key intermediate 5,7,3',4'-tetrabenzyloxy-3-O-propargylquercetin,which subsequently ‘clicked’ with azido containing glycosides,poly(ethylene glycol)(PEG) or oligo(ethylene glycol)(OEG) to provide the fully protected quercetin conjugates 12~19.After global deprotection,the resulting quercetin conjugates were evaluated on hypoglycemic activities at 3T3-L1 adipocyte level.The results showed that conjugates 24,26 and 27 exhibited good hypoglycemic effects.
