The chemical synthesis of phosphorothioate/phosphodiester analogues of 2-methoxy-lysophosphatidylethanolamine has been described. For the preparation of phosphorothioate derivatives oxathiaphospholane approach has been employed. The phosphodiester compounds were prepared by OXONE® oxidation of corresponding phosphorothioates. Each lysophospholipid analogue was synthesized as a series of four compounds, bearing different fatty acid residues both saturated (14:0, 16:0, 18:0) and unsaturated (18:1). The methylation of glycerol 2-hydroxyl function was applied in order to increase the stability of prepared analogues by preventing 1→2 acyl migration. The cytotoxicity of newly synthesized 2-methoxy-lysophosphatidylethanolamine derivatives was evaluated with resazurin-based method in prostate cancer PC3 cell line. The highest reduction of cell viability was noted for LPE analogues containing myristoyl acyl chain.
Graphical abstract2-OMe-LPE phosphorothioates (myristoyl, palmitoyl, stearoyl and oleoyl derivatives) were prepared by oxathiaphospholane method; their oxidation with OXONE® led to corresponding phosphodiester analogues. The products were tested for their cytotoxicity toward prostate cancer PC3 cell line.Figure optionsDownload full-size imageDownload as PowerPoint slide
