1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium)

1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) (1-Arachidonoyl-sn-glycerol 3-phosphate (sodium)) is a phospholipid with arachifonic acid at the sn-1 position. 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) binds to the LPA2/EDG4 receptor (EC50 of 10 nM). 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) can be found in rat brain as 37% of the arachidoinic acid-containing lysophosphatidic acid species. 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) is the precursor to 1-arachidonoyl glycerol. 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) can prevent TNF-α and IL-6 secretion in wild type LPS-stimulated dendritic cells. 1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) reduces differentiation of HT-29 colon carcinoma cells into goblet cells when sodium butyrate is present[3][4].
