Description :
Ac-RYYRIK-NH2 is a potent and partial agonist on ORL1 transfected in CHO cells (Kd=1.5 nM) and behaves as a endogenous ligand of ORL1. Ac-RYYRIK-NH2 is a specific antagonist for the activation of G protein and competitively antagonizes the stimulation of [35S]-GTPgS binding to G proteins by nociceptin/orphanin FQ (noc/OFQ) in membranes and sections of rat brain.
