phosphatidic

Phosphatidic acid is a phospholipid and an intermediate in glycerolipid biosynthesis. It is a transient intermediate in the synthesis of various phospholipid species that is synthesized de novo in cells via multiple routes, including the glycerol-3 phosphate and dihydroxyacetone phosphate pathways, enzymatic conversion of phosphatidylcholine by phospholipase D, and acetylation of lysophosphatidic acid by lysoPA-acyltransferase, among others. It has roles in shaping cellular membranes, cellular signaling, vesicle fission and fusion, as well as mitochondrial division and fusion. It stimulates respiratory burst in neutrophils independent of diacylglycerol and activates monoacylglycerol acyltransferase, phospholipase C (PLC), Ras, and phosphatidylinositol 4-phosphate (PIP4) kinase in several cell lines. Phosphatidic acids (egg) is a mixture of phosphatidic acids isolated from chicken egg with fatty acids of variable chain lengths.

Cyclic Phosphatidic Acids (cPAs) are naturally occurring lysophosphatidic acid (LPA) analogs, characterized by a 5-membered ring formed between the sn-2 hydroxy group and the sn-3 phosphate. Carba-derivatives of cPA (ccPA) modify the sn-2 (2-ccPA) or sn-3 (3-ccPA) linkage, hindering the conversion of cPA into LPA. Oleoyl 3-Carbacyclic Phosphatidic Acid (3-ccPA 18:1) incorporates the 18:1 fatty acid oleate at the sn-1 position on the glycerol backbone, acting as a cyclic LPA analog. This compound, at a concentration of 25 μM, blocks MM1 cells' transcellular migration through mesothelial cell monolayers induced by fetal bovine serum (by 90.1%) or LPA (by 99.9%), without impeding cell proliferation. Additionally, 3-ccPA 18:1, in the 0.1-1.0 μM range, notably suppresses autotaxin, which plays a vital role in various cancer cell behaviors including survival, growth, migration, invasion, and metastasis.

1-Octadecyl lysophosphatidic acid (1-octadecyl LPA) is a LPA analog containing stearic acid at the sn-1 position. LPA binds to one of five different G protein linked receptors to mediate a variety of biological responses including cell proliferation, smooth muscle contraction, platelet aggregation, neurite retraction, and cell motility. Alkyl ether-linked LPA derivatives have a higher platelet aggregating activity than the acyl derivatives, most likely stemming from an alkyl-specific LPA receptor. For example, 1-octadecyl LPA has a platelet aggregating EC50 value of 9 nM versus 1-octadecanoyl LPA which has an EC50 value of 177 nM.

1-Oleoyl Lysophosphatidic Acid (1-Oleoyl LPA) is a biologically active phospholipid that can exert multiple biological effects in various disease states of the kidney by activating a complex network of at least six homologous G protein-coupled receptors and their heterotrimeric G proteins. 1-Oleoyl Lysophosphatidic Acid promotes polarization of BV-2 and primary murine microglia toward an M1-like phenotype and can be used to study cancer and atherosclerosis.

Notably, 1-linoleoyl LPA serum concentrations are elevated in mice with NCTC clone 2472 tumors, while its plasma levels are reduced in primary progressive multiple sclerosis patients—unlike in those with relapsing-remitting multiple sclerosis—and inversely associate with the severity of neurological deficits.

PLD is implicated in numerous disease-related pathways, such as diabetes, atherogenesis, obesity, tumorigenesis, immune responses, and neuroendocrine functions [1].
