C-021 dihydrochloride 是有效的 CC 趋化因子受体 4 (CCR4) 拮抗剂。C-021 dihydrochloride 有效抑制人和小鼠的功能趋化性，IC50 分别为 140 nM 和 39 nM。C-021 dihydrochloride 以 IC50 为 18 nM 来有效阻止人 CCL22 衍生的 [35S]GTPγS 与受体结合。 Product description： C-021 dihydrochloride is a potent CC chemokine receptor-4 (CCR4) antagonist. C-021 dihydrochloride potently inhibits functional chemotaxis in human and mouse with IC50s of 140 nM and 39 nM, respectively. C-021 dihydrochloride effectively prevents human CCL22-derived [35S]GTPγS from binding to the receptor with an IC50 of 18 nM.
