  Chemoenzymatic synthesis of 1-O-acyl-3-O-(6'-O-acyl-β-D-galactopyranosyl)-sn-glycerol

  摘要：

  Convenient synthesis of 1-O-acyl-3-O-(6'-O-acyl-beta-D-galactopyranosyl)-sn-glycerol was studied. The lipase from Achromobacter sp, catalyzed acylation of 3-O-beta-D-galactopyranosyl-sn-glycerol, which contains two primary hydroxyl functions, proceeded regioselectively to furnish 1-O-acyl-3-O-beta-D-galactopyranosyl-sn-glycerol.

  1-O-Acyl-3-O-(6'-O-acyl-β-D-galactopyranosyl-sn-glycerol, which was isolated from a nitrogen-fixing freshwater cyanobacterium, Anabaena flos-aquae f. flos-aquae, was synthesized by utilizing lipase-catalyzed acylation.The antitumor-promoting activities of these galactolipids were evaluated using a short-term in vitro assay of Epstein-Barr virus activation in Raji cells induced by 12-O-tetradecanoyl-phorbol 13-acetate (TPA). The glyceroglycolipids which have a palmitoleoyl residue at the 1-O-position exhibited more potent activities than the others in this assay.

  Lipase from Rhizopus arrhizus catalyzed deacylation of two classes of glyceroglycolipids, monogalactosyl diacylglycerol(MGDG), and digalactosyl diacylglycerol(DGDG), proceeded regiospecifically to furnish sn-1 lysoglyceroglycolipids quantitatively. The lipase also catalyzed complete acyl migration of sn-1 lysoglycerogalacto-lipids leading to sn-2 lysoglycerogalactolipids.
