Abstract

We describe the design, synthesis, and evaluation of novel disubstituted cyclohexanes as potent CCR2 antagonists. Exploratory SAR studies led to the cis-disubstituted derivative 22, which displayed excellent binding affinity for CCR2 (binding IC50 = 5.1 nM) and potent functional antagonism (calcium flux IC50 = 18 nM and chemotaxis IC 50 = 1 nM). Site-directed mutagenesis studies with 22 suggest the compound is binding near the key receptor residue Glu291, however, 22 is not reliant on Glu291 for its binding affinity.
