Biochem/physiol Actions

High affinity antagonist for CCR1 and CCR3 receptors, agonist at CCR2 and CCR5 receptors
J113863 is a high affinity antagonist for CCR1 and CCR3 receptors. Also both J113863 and its enantiomer c exhibit low binding affinity toward CCR2 and CCR5 where they activate three G_i and two G₀ protein isoforms. J113863 does not activate G₁₂ protein isoform. J113863 binding to CCR2 and CCR5 induce the recruitment of b-arrestin 2 whereas UCB35625 did not. J113863 and UCB35625 are biased ligands for the chemokine receptors CCR2 and CCR5.
