Dioctanoylphosphatidic acid sodium serves as a modulator of phagocyte respiratory bursts, a precursor to diacylglycerol and lyso-phosphatidic acid, and influences the phosphorylation of the mammalian target of rapamycin (mTOR). Additionally, it enhances the viability of gallbladder cancer cells inhibited by histone deacetylase inhibitors (HDACI). This compound is derived from glycerophospholipids through the action of phospholipase D.
