The chemical synthesis of phosphorothioate/phosphorodithioate analogues of 2-methoxy-lysophosphatidylcholine has been described. For the preparation of new sulfur derivatives of lysophosphatidylcholine both oxathiaphospholane and dithiaphospholane approaches have been employed. Each lysophospholipid analogue was synthesized as a series of five compounds, bearing different fatty acid residues both saturated
The chemical synthesis of five new metabolicallystabilized 2-OMe-LPA analogues (1a–e) possessing different fatty acid residues has been performed by phosphorylation of corresponding 1-O-acyl-2-OMe-glycerols which were prepared by multistep process from racemic glycidol. The now analogues were subjected to biological characterization as autotaxin inhibitors using the FRET-based, synthetic ATX substrate
