ccr-6 inhibitor 1

CCR6 inhibitor 1 is an effective and selective inhibitor of CCR6 (IC50 of monkey and human CCR6 was 0.45 nM and 6 nM, respectively). CCR6 is associated with both autoimmune and non-autoimmune diseases, so CCR6 inhibitor 1 is useful for in vitro and in vivo pathophysiology studies as a small molecule inhibitor of CCR6.

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).
