CCR2 Covalent-IN-14

CCR2 covalent-IN-14 is a covalent, negative allosteric modulator (NAM) of CCR2, binds to intracellularly pocket of CCR2 with Ki of 4 nM.CCR2 covalent-IN-14 is more potent than non-covalent analogue and wash-resistant in functional assays (IC50=33 nM in GTPγS binding assay on U2OS-CCR2 cell membranes, IC50=4 nM in β-arrestin recruitment assays).CCR2 covalent-IN-14 displays little to no inhibitory potency on CCR1 and CCR5.The affinity of CCR2 covalent-IN-14 for both the C70S and C75S CCR2 mutants is significantly decreased compared to WT CCR2.
