Description
1-Arachidonoyl lysophosphatidic acid is a phospholipid containing arachidonic acid at the
sn-1 position. It has been found in rat brain as 37% of the arachidonic acid-containing lysophosphatidic acid (LPA) species and is a precursor to 1-arachidonoyl glycerol (1-AG; ). 1-Arachidonoyl lysophosphatidic acid binds to the LPA
2/EDG4 receptor with an EC
50 value of approximately 10 nM. It prevents TNF-α and IL-6 secretion in wild-type but not
Lpa2-/- dendritic cells stimulated by LPS. It also decreases differentiation of HT-29 human colon carcinoma cells to goblet cells in the presence of sodium butyrate.
