An orally available human C-C chemokine receptor type 2 (CCR2) antagonist, with potential immunomodulating and antineoplastic activities. Upon oral administration, CCR2 antagonist CCX872-B specifically binds to CCR2 and prevents the binding to its cognate endothelium-derived chemokine ligand CCL2 (monocyte chemoattractant protein-1 or MCP1). This may result in the inhibition of both CCR2 activation and CCR2-mediated signal transduction, which may inhibit inflammatory processes, angiogenesis, tumor cell migration, and tumor cell proliferation. The G-protein coupled receptor CCR2 is expressed on the surface of monocytes and macrophages, and stimulates their migration and infiltration; it plays a key role in inflammation. CCR2 is overexpressed in certain cancer cell types, where it is involved in angiogenesis, tumor cell migration and proliferation. Check for active clinical trials using this agent. (NCI Thesaurus)
