  Synthesis and anti-tumor-promoting activity of glycoglycerolipid analogues lacking the glycerol backbone

  摘要：

  Glycoglycerolipid analogues lacking the glycerol backbone were prepared through a lipase catalyzed transesterification Of beta-D-galactosylethylene glycol. The inhibitory effect of the resultant isomeric hexanoates at the primary alcoholic positions, beta-D-galactosylethylene glycol itself and nonyl beta-D-galactopyranoside, was tested on Epstein-Barr virus early antigen (EBV-EA) activation in Raji cells promoted by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA), as a primary screening test for inhibitors of tumor promotion. All the compounds assayed were found to be less active than the reference 2-O-beta-D-galactopyranosylglycerol derivatives, of which they are simplified models, indicating that the anti-tumor-promoting activity is very closely related to the presence of a free hydroxymethylene group on the glycerol-like aglycone moiety.

  decreases with increasing alkyl chain length. Decyl β‐d‐galactopyranoside was insoluble in water, but soluble in ethanol. Dissolution of alkyl β‐d‐galactopyranoside in water is an endothermic process with dissolution enthalpies greater than zero. Nonyl β‐d‐galactopyranoside had an excellent emulsifying property, better foaming ability and the best foam stability. The CMC values of alkyl β‐d‐galactopyranosides
