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-Palmitoyl lysophosphatidic acid (1-Palmitoyl LPA) is a LPA analog containing palmitic acid at the sn-1 position. LPA binds to one of five different G protein-coupled receptors (GPCRs) to mediate a variety of biological responses including cell proliferation, smooth muscle contraction, platelet aggregation, neurite retraction, and cell motility. In addition to playing a role in the aforementioned biological responses, 1-palmitoyl LPA enhances the action of β-lactam antibiotics (ampicillin, piperacillin, and ceftazidime) on various strains of Pseudomonas aeruginosa, a pathogen associated with pulmonary disease and pneumonia, via binding both Ca2+ and Mg2+.

1-Linoleoyl lysophosphatidic acid (1-linoleoyl LPA), a glycerophospholipid with linoleic acid at its sn-1 position, acts as an LPA2 receptor agonist and is the predominant LPA form in both mouse and human plasma. This compound preferentially boosts intracellular calcium in Sf9 cells expressing the LPA2 receptor (EC50 = ~10 nM), compared to those with LPA1 and LPA3 receptors (EC50s = ~200 and ~80 nM, respectively). 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.

1-Palmitoyl Lysophosphatidic Acid is an analog of LPA and improves the the action of ampicillin, piperacillin, and ceftazidime on various strains of P. aeruginosa via binding both Ca2+ and Mg2+.

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.

Oleoyl-L-alpha-lysophosphatidic acid sodium salt is an essential cell membrane biosynthetic metabolite that mediates signal transduction by interacting with G protein-coupled receptors (GPCRs) (ie, LPA receptors). It is the receptor of LPA1 and LPA2. endogenous agonist.

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.

1-Arachidoyl lysophosphatidic acid (1-arachidoyl LPA), a glycerophospholipid with arachidic acid at the sn-1 position, functions as an agonist for lysophosphatidic acid receptor 1 (LPA1). It effectively induces calcium mobilization in primary human lung fibroblasts at an EC50 value of 3.6 µM, given these cells inherently express LPA1 but lack expression of LPA2-LPA6 receptors. Additionally, at a concentration of 2.5 µM, 1-arachidoyl LPA binds to the ligand-binding domain of peroxisome proliferator-activated receptor γ (PPARγ) in a cell-free environment. This compound has also been detected in human urine.

LY294002 (SF 1101) is a broad-spectrum inhibitor of PI3K, inhibiting PI3Kα, PI3Kδ, and PI3Kβ (IC50=0.5 0.57 0.97 μM). LY294002 is also an inhibitor of DNA-PK (IC50=1.4 μM) and an inhibitor of CK2 (IC50=98 nM). LY294002 activates apoptosis and autophagy.

(R)-Lisofylline ((R)-Lisophylline) is an inhibitor of lysophosphatidic acid acyltransferase (IC50 = 0.6 µM) that interrupts IL-12 signaling-mediated STAT4 activation, making it useful for studies on the treatment of type 1 diabetes and autoimmune disorders.

AS2717638 is an orally active and selective lysophosphatidic acid receptor 5 (LPA5) antagonist (IC50: 38 nM for hLPA5). It also significantly improves PGF2α-, PGE2-, and AMPA-induced allodynia.

Autotaxin-IN-3 is an inhibitor of Autotaxin (IC50 = 2.4 nM) which is responsible for the increase in lysophosphatidic acid in ascites and plasma.

DBIBB is a non-lipid agonist of specific lysophosphatidic acid (LPA2) type 2 G-protein-coupled receptor. It is a potentially active molecule for the treatment of acute radiation syndrome caused by high intensity gamma rays on hematopoietic and gastrointestinal systems. It is an intermediate in organic synthesis and drug research. DBIBB can be used to prepare various compounds that reduce gastrointestinal radiation syndrome, increase intestinal crypt survival and intestinal cell proliferation, and reduce cell apoptosis.

PF-8380 is an effective and orally available autotaxin inhibitor (IC50: 2.8 nM, in isolated enzyme assay; 101 nM, in the human whole blood). It modulates lysophosphatidic acid (LPA) levels in vivo vitro by directly inhibiting autotaxin; reduces LPA levels both in plasma and at the site of inflammation.

PAT-048 is an effective and selective autotaxin inhibitor. PAT-048 reduces dermal fibrosis in vivo.

LPA receptor antagonist-1 (example 52) serves as an antagonist for the lysophosphatidic acid (LPA) receptor and is applicable in various types of studies [1].

XY-4, a derivative of 1-palmitoyl lysophosphatidic acid (1-palmitoyl LPA094) and an agonist of peroxisome proliferator-activated receptor γ (PPARγ), effectively induces reporter gene expression in RAW 264.7 macrophages harboring a peroxisome proliferator-response element (PPRE) at a concentration of 5 µM. Unlike its action on PPARγ, XY-4 does not serve as an agonist for lysophosphatidic acid receptor 1 (LPA1), LPA2, or LPA3. Furthermore, at a lower concentration of 1 µM, it promotes platelet aggregation in vitro and triggers carotid artery neointima formation in rats.

BMP-22 is an inhibitor of autotaxin (IC50 = 170 nM). It is selective for autotaxin over the phosphodiesterases NPP6 and NPP7 at 10 μM. BMP-22 (0.1-1,000 nM) inhibits autotaxin-mediated production of lysophosphatidic acid (LPA) from lysophosphatidylcholine in vitro in a concentration-dependent manner. It inhibits LPC-dependent MM1 cell invasion of a human umbilical vein endothelial cell (HUVEC) monolayer. BMP-22 (0.5 mg/kg per day) decreases the number of lung metastatic foci in a B16/F10 syngeneic mouse melanoma model of lung metastasis.
