C 021 dihydrochloride is a potent CCR4 antagonist. C-021 (4-Quinazolinamine, 2-[1,4'-bipiperidin]-1'-yl-N-cycloheptyl-6,7-dimethoxy-) dihydrochloride potently inhibits functional chemotaxis in humans and mice with IC50s of 140 nM and 39 nM, respectively. It effectively prevents human CCL22-derived [35S]GTPγS from binding to the receptor (IC50: 18 nM).

GSK2239633A is an allosteric antagonist of CC-chemokine receptor 4 (CCR4) with a pIC50 of 7.96 for the binding of [125I]-TARC to human CCR4.

CCR4 antagonist 3-1 is a less active chemokine receptor 4 (CCR4) antagonist that inhibits [125I]TARC (thymus and activation-regulated chemokine) with an IC50 value of 1.7 μM. CCR4 antagonist 3-1 inhibits the binding of radiolabeled [125I]TARC and macrophage-derived chemokine ( MDC) to CEM cell surface and inhibits TARC-mediated CEM cell migration in vitro with an IC50 value of 6.4 μM. CCR4 antagonist 3 inhibited the binding of radiolabeled [125I]TARC and macrophage-derived chemokine (MDC) to the CCR4 receptor on the surface of CEM cells and inhibited TARC-mediated migration of CEM cells in vitro with an IC50 value of 6.4 μM.

CCR4 antagonist 2 (Compound 31) is a novel, potent, orally bioavailable small molecule antagonist of CC chemokine receptor 4 (CCR4) that inhibits Treg trafficking into the Tumor Microenvironment without suppressing the number of Treg in healthy tissues. CCR4 antagonist 2 (Compound 31) exhibits IC50 values of Ca2+ flux and [chemotaxis] CTX at 40 nM and 70 nM, respectively.

CCR2 antagonist 4 (Teijin compound 1) is a potent and specific CCR2 antagonist with IC50 values of 180 nM and 24 nM for CCR2 inhibition and MCP-1-induced chemotaxis inhibition, respectively.

CCR2 antagonist 4 hydrochloride is a specific CCR2 antagonist (IC50s: 180 nM for CCR2b). It potently inhibits MCP-1-induced chemotaxis (IC50: 24 nM).

CCR4 antagonist 3 is an orally active, potent and selective CCR4 antagonist. CCR4 antagonist 3, featuring a novel piperidinyl-azetidine motif, has IC 50 s of 22 nM and 50 nM in the calcium flux and CTX assay. CCR4 antagonist 3 has antitumor activity.
