In Vitro	[3H]ac-RYYRWK-NH2 binding to rat cortical membranes revealed a single high affinity site for [3H]ac-RYYRWK-NH2 (Kd=0.071 nM)[1]. Naloxone benzoylhydrazone displaced [3H]acRYYRWK-NH2 binding to rat cortical membranes (Ki=104 nM) and human ORL1 (Ki=136 nM) as well as [125I]Tyr14-NC-OH to ORL1 (Ki=37 nM) has no affinity for µ-, κ- or δ-opioid receptors[1].
