  Synthesis of structural variants of Staphylococcus aureus lipoteichoic acid (LTA)

  摘要：

  Based on 1,2-O-isopropylidene-sn-glyerol, which is readily available from D-mannitol, five chiral building blocks for the construction of structural variants of Staphylococcus aureus LTA designed and synthesized. Ligation of these building blocks led readily to the target molecules 1 and 2. They demonstrated that the D-alanine residues at the glycerophosphate backbone are decisive for the activation of the immune system. (C) 2004 Elsevier Ltd. All rights reserved.

  Based on 1,2-O-isopropylidene-sn-glycerol five chiral building blocks containing differently modified glycerol residues were required for the synthesis of the target molecule 2. One of these building blocks is diacylglyceryl beta-gentiobioside carrying a phosphite residue at 6b-O position. Ligation of these five building blocks led to the desired glycerol phosphate backbone to which D-alanyl residues were attached, thus generating after O-deprotection the target molecule 2, a bisamphiphilic structural variant of Staphylococcus aureus LTA. This compound displayed higher potency in terms of cytokine release by human blood leukocytes than the monoamphiphilic variant LTA. (c) 2006 Elsevier Ltd. All rights reserved.
