    Product Description

    1-Palmitoyl-2-hydroxy-sn-glycero-3-PA (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.1,2 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+.3
