Lysophosphatidylserine (LysoPS) is an endogenous lipid mediator that specifically activates membrane proteins of the P2Y and its related families of G protein coupled receptors (GPCR), GPR34 (LPS1), P2Y10 (LPS2), and GPR174 (LPS3). Here, in order to increase potency and receptor selectivity, we designed and synthesized LysoPS analogues containing the conformational constraints of the glycerol moiety. These reduced structural flexibility by fixation of the glycerol framework of LysoPS using a 2-hydroxymethyl-3-hydroxytetrahydropyran skeleton, and related structures identified compounds which exhibited high potency and selectivity for activation of GPR34 or P2Y10. Morphing of the structural shape of the 2-hydroxymethyl-3-hydroxytetrahydropyran skeleton into a planar benzene ring enhanced the P2Y10 activation potentcy rather than the GPR34 activation.
