    The CC chemokines may play an important role in the pathogenesis of chronic inflammatory diseases including rheumatoid arthritis, and their effects are thought to be mediated through CCR1 receptors. Several nonpeptide CCR1 receptor antagonists that showed high affinity for human CCR1 receptors have been identified; however, their effectiveness in animal models of inflammatory diseases has been scarcely demonstrated, probably due to species selectivity of the antagonists. To elucidate the pathophysiological role of CCR1 receptors in murine models of disease, we looked for a potent antagonist for both murine and human CCR1 receptors. Screening of our chemical collection for inhibition of I-125-MIP-1 alpha. binding to human CCR1 receptors transfected in CHO cells led to the identification of xanthene-9-carboxamide la as the lead compound. Derivatization of 1a by quaternarizing the piperidine nitrogen with various alkyl groups and by installing substituents into the xanthene moiety dramatically improved the inhibitory activity against both human and murine CCR1 receptors. As a result, 2q-1 showing IC50 values of 0.9 and 5.8 nM for human and murine CCR1 receptors, respectively, was discovered. This compound is the first murine CCR1 receptor antagonist and may be a useful tool for clarifying the role of CCR1 receptors in murine models of disease.
