JKC-363 Usage And Synthesis

Uses

JKC363, a selective melanocortin MC4 receptor antagonist, has a 90-fold higher affinity at the MC4 receptor (IC50=0.5 nM) than at the MC3 receptor (44.9 nM). JKC-363 blocks the stimulatory effect of α-MSH on TRH release. Anti-hyperalgesic effect[1][2].

IC 50

MC4R
