DL 175 is a 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.
