(2S)-OMPT

Lysophosphatidic acid (LPA) is a potent lipid mediator that elicits its effect through four distinct receptors - LPA1/EDG-2, LPA2/EDG-4, LPA3/EDG-7 and LPA4/GPR23. OMPT is a selective agonist of the lysophosphatidic acid 3 (LPA3) receptor. It exhibits EC50 values of 68 nM and >6.8 µM for calcium mobilization in LPA1 and LPA2-expressing Sf9 cells, respectively. The (2S)-OMPT enantiomer is 5- to 20-fold more active than (2R)-OMPT in calcium release assays in both LPA3-transfected Sf9 and rat hepatoma Rh7777 cells.Formal Name: 9Z-octadecenoic acid, (2S)-3-[(hydroxymercaptophosphinyl)oxy]-2-methoxypropyl ester, triethyl ammonium salt (1:2).
