A series of fused bicyclic and urea derivatives of spirocyclic compounds were designed, synthesised and evaluated in vitro as potent CCR1 antagonists. In particular, 4 (7 nM), 44 (1.3 nM), 48 (0.89 nM) and 50 (0.63 nM) were the most potent hCCR1 antagonists in this series of compounds. Moreover, some of these substances demonstrated good rodent cross-over, especially 46 which exhibited very high rat CCR1 binding affinity with an IC50 value of 16 nM. (C) 2013 Elsevier Ltd.
