1-palmitoyl lysophosphatidic acid

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-Palmitoyl Lysophosphatidic Acid (sodium salt) is an LPA derivative and endogenous metabolite, suitable for related research in the field of life sciences.

16:0 Cyclic LPA (1-Palmitoyl-sn-glycero-2,3-cyclic-phosphate) ammonium is a type of palmitoyl cyclic lysophosphatidic acid.

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.

Palmitoyl 3-carbacyclic phosphatidic acid, a palmitoylated Carba-like cyclophosphatidic acid and LPA (lysophosphatidic acid) analog, possesses distinct biological activities compared to LPA, including the inhibition of RhoA activation and melanoma cell migration. This compound has demonstrated efficacy in inhibiting experimental lung metastasis and reducing tumor nodule counts in a B16-F0 xenograft mouse model [1].

1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PA (1-palmitoyl-d9LPA) serves as an internal standard for the quantification of 1-palmitoyl LPA using GC- or LC-MS. This compound, an analog of LPA with palmitic acid at the sn-1 position, activates reporter gene expression in PC12 cells fitted with human lysophosphatidic acid receptor 4 (LPA4) at 0.01 to 10 µM concentrations. Additionally, 1-palmitoyl LPA prompts aggregation in isolated human platelets within the 12-300 µM range, a process reversible by prostaglandin E1 (PGE1), theophylline, or EDTA. It also interacts with calcium and magnesium to boost the efficacy of ampicillin, piperacillin, and ceftazidime against P. aeruginosa strains from cystic fibrosis patients.
