Monocyte chemoattractant protein (MCP-1/CCL2) is a CC chemokine and binds to chemokine receptor 2 (CCR2), which is expressed on the majority of blood born monocytes. CCR2 antagonism has been suggested as a viable approach for the treatment of a variety of inflammatory and autoimmune diseases including rheumatoid arthritis, multiple sclerosis and atherosclerosis. The SAR evolution that led to the clinical candidate MK-0812 will be discussed. MK-0812 is a potent and selective CCR2 antagonist with low nM affinity for CCR2 on human monocytes and low nM in the chemotaxis assay. It has good PK profiles in preclinical species and demonstrated efficacy in animal models.
