Notes: CCR2 antagonist is an antagonist of chemokine (C-C motif) receptor 2 (CCR2).{49940} It binds to CCR2 in a radioligand binding assay using peripheral blood mononuclear cells (PBMCs; IC50 = 5.1 nM). CCR2 antagonist inhibits chemotaxis induced by chemokine (C-C motif) ligand 2 (CCL2) in PBMCs (IC50 = 1 nM). In vivo, CCR2 antagonist (2 mg/kg) reduces hepatic Ly6C+ monocyte recruitment and viral clearance in mice infected with hepatitis B virus (HBV).{49941}
