Potent, selective hCCR2 antagonist. Exhibits potenct antagonism against monocyte chemoattractant molecule binding to hCCR2 and chemotaxis activity (IC50 values are 3.7 and 4.7 nM respectively). Also displays weak hERG activity; inhibits the hERG potassium current (IC50 = 84μM). Orally bioavailable.
