LPAR5

LPAR5 (lysophosphatidic acid receptor 5) is a G protein-coupled receptor for lysophosphatidic acid (LPA) and belongs to the non-EDG family of LPA receptors, where it mediates extracellular lipid signaling through multiple G-protein pathways including G12/13, Gq, and cAMP-associated signaling mechanisms[1][2]. Mechanistically, LPAR5 activation regulates cytoskeletal remodeling, intracellular calcium mobilization, receptor internalization, and inflammatory signaling, thereby influencing cell migration and immune-cell responses[2][3]. In the central nervous system, the LPA-LPAR5 axis promotes microglial activation and induces a pro-inflammatory and migratory phenotype characterized by activation of MAPK, AKT, NF-κB, STAT, and related signaling pathways[3][4]. Disease-associated studies further demonstrate that LPAR5 contributes to neuropathic pain, neuroinflammatory processes, itch, and cancer-related phenotypes, while altered receptor activity has been linked to tumor cell proliferation, migration, invasion, and modulation of tumor immunity[4][5]. Compared with the classical EDG-family receptors LPAR1-3, LPAR5 belongs to the structurally distinct non-EDG subgroup and exhibits unique signaling properties that include robust coupling to G12/13 and Gq-dependent pathways as well as context-dependent regulation of immune-cell function[1][2]. For experimental applications, selective small-molecule antagonists including AS2717638, Compound 3, and TCLPA5 have been used to suppress LPAR5-dependent inflammatory signaling and represent valuable pharmacological tools for investigating neuroinflammation, immune regulation, and LPA receptor biology[3][4][5].

    N-PTyrosine PA ammonium
    Modulator
    N-PTyrosine PA (N-Palmitoyl-tyrosine phosphoric acid) ammonium is a lysophosphatidic acid (LPA) receptor modulator, which exhibits weak inhibitory activity against LPA1 and partial agonist properties towards LPA5. N-PTyrosine PA ammonium inhibits the activation of LPA receptors and downstream responses by competing with agonists for binding sites. N-PTyrosine PA ammonium can induce morphological changes and aggregation, and also inhibit LPA-induced morphological changes through receptor desensitization caused by pre-incubation. N-PTyrosine PA ammonium can be used in the research of related diseases such as atherosclerosis and acute ischemic syndromes (e.g., unstable angina, myocardial infarction, stroke).

    BrP-LPA sodium
    Antagonist
    BrP-LPA sodium is a pan-opposite agent for lysophosphatidic acid (LPA). It has antagonistic activity against LPA1 (IC50 = 4520 nM), LPA2 (IC50 = 468 nM), LPA3, and LPA4. BrP-LPA sodium also has partial agonistic activity for LPA5, with its EC50 being 1282 nM. BrP-LPA sodium has ATX inhibitory activity. BrP-LPA sodium effectively inhibits the migration and invasion of breast cancer cells. BrP-LPA sodium achieves tumor regression and anti-angiogenesis in mice breast cancer xenograft model. BrP-LPA sodium can be used for the study of breast cancer.
