New 1-acyl-sialosyl-glycerol derivatives (1a--d alpha, 1a--d beta, 2 alpha, 2 beta, which mimic the structure of the capsular polysaccharide of group C meningococcal were synthesized by the use of a chiral glycerol derivative, and were found to have phospholipases A2 and C inhibitory activities. Furthermore, synthesis of 2-palmitoyl-sialosyl-glycerol derivative (4 alpha, 4 beta, 5 alpha, 5 beta), galactosyl-glycerol
