Antitumor-Promoting Activities of Various Synthetic 1-O-Acyl-3-O-(6'-O- Acyl-.BETA.-D-Galactopyranosyl)-sn-Glycerols Related to Natural Product from Freshwater Cyanobacterium Anabaena flos-aquae f.flos-aquae.
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.
