生物活性

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[1].

IC50 Target

Kd: 1.5 nM (ORL1 transfected in CHO cells)[1]
体内研究
(In Vivo)

Ac-RYYRIK-NH2 (intracerebroventricularly (i.c.v.) inhibits spontaneous locomotor activity in mice with an ID50 of 0.07 nmol. Co-administration of noc/OFQ and Ac-RYYRIK-NH2 lead to additive effects in Male Swiss mice[1].
