Potent and selective GPR84 biased agonist (EC50 = 33 nM). Exhibits no significant activity in a panel of 168 other GPCRs. Exhibits bias for G protein signaling pathways. Induces morphological changes in primary murine bone marrow-derived macrophages (BMDMs) in a cellular impedance assay, and promotes phagocytosis by M1 polarized U937 cells. Induces migration of primary human monocytes, but has no effect on macrophage chemotaxis.
PSB-1584 is a Potent Agonist of the Orphan G Protein-Coupled Receptor 84 (GPR84). GPR84, a Gi protein-coupled receptor that is activated by medium-chain (hydroxy)fatty acids, appears to play an important role in inflammation, immunity, and cancer.
PSB-17365 is a potent GPR84 agonist. PSB-17365 exhibits EC50 values vs. GPR84 of 2.5nM in a cAMP accumulation assay, and 100nM in a β-arrestin 2 recruitment assay. No direct binding affinities are provided. PSB-17365 is selective for GPR84 compared to other free fatty acid receptors (FFAR1 and FFAR4). GPR84, a Gi protein-coupled receptor that is activated by medium-chain (hydroxy)fatty acids, appears to play an important role in inflammation, immunity, and cancer.
