The chemical synthesis of five new metabolically stabilized 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
五种具有不同脂肪酸残基的新的代谢稳定的2- OMe -LPA类似物(1a - e)的化学合成通过相应的1- O-酰基2- OMe-甘油的磷酸化而进行,这些多酚是通过外消旋多步法制备的缩水甘油。现在的类似物使用基于FRET的合成ATX底物FS-3进行生物学鉴定,作为自分泌运动抑制剂。在测试的化合物中,1 - O-油酰基-2- OMe - LPA(1e)似乎是最有效的化合物,显示出与未修饰的1- O相似的ATX抑制活性-油酰基-LPA。平行测试表明,对于相应的1 - O-酰基-2- OMe-硫代磷酸酯(2a-e,如我们先前所述合成)也观察到了类似的趋势。与未修饰的1 - O-油酰基-LPA相反,发现1 - O-油酰基-2- OMe - LPA(1e)对碱性磷酸酶具有抗性。
