Short-chain phosphatidic acid derivatives, dioctanoyl glycerol pyrophosphate (DGPP 8: 0, 1) and phosphatidic acid 8: 0 (PA 8: 0, 2), were previously identified as subtype-selective LPA1 and LPA3 receptor antagonists. Recently, we reported that the replacement of the phosphate headgroup by thiophosphate in a series of fatty alcohol phosphates (FAP) improves agonist as well as antagonist activities at LPA GPCR. Here, we report the ...
