1-arachidonoyl lysophosphatidic acid

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-Arachidonoyl lysophosphatidic acid binds to the LPA2/EDG4 receptor with an EC50 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.

1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) (1-Arachidonoyl-sn-glycerol 3-phosphate (sodium)) 是一种含有花生四烯酸的磷脂，能够与LPA2/EDG4受体结合 (EC50为10 nM)。该化合物在大鼠脑中占含花生四烯酸溶血磷脂酸种类的37%，并作为1-花生四烯酰甘油的前体。它能够抑制野生型LPS刺激的树突状细胞分泌TNF-α和IL-6。此外，在存在丁酸钠时，1-Arachidonoyl-2-hydroxy-sn-glycero-3-PA (sodium) 可抑制HT-29结肠癌细胞的杯状细胞分化。
