Chemoenzymatic synthesis and antitumor promoting activity of 6′- and 3-esters of 2-O-β-d-glucosylglycerol Original Research Article

Through a simple chemoenzymatic approach 6′- and 3-esters of 2-O-β-d-glucosylglycerol , with short-medium length fatty acid acyl chains, were prepared. The study of their in vitro antitumor promoting effect on Epstein–Barr virus early antigen (EBV-EA) activation, in comparison with that of the 1-esters previously described, confirms the significant activity of such monoacylated glycoglycerolipid analogues and establishes for the glucose series that the 1-substitution and the hexanoyl chain are the proper structural features for the maximum activity.
