The discovery of a novel series of CXCR3 antagonists is described. Starting from an HTS positive, iterative optimization gave potent compounds (IC(50) 15 nM in a chemotaxis assay). The strategy employed to improve the metabolic stability of these derivatives is described. (C) 2010 Elsevier Ltd. All rights reserved.
