体外研究(In Vitro)
5-Guanidinonaltrindole (5-GNTI) also binds to human μ- and δ-opioid receptors with Kis of 36.9±2.3 nM and 70.0±0.3 nM, respectively.5-Guanidinonaltrindole is most effective at κ-opioid receptors (pA2=10.4±0.10), with substantially lower antagonist potency at μ-opioid (pA2=8.49±0.09) and δ-opioid receptors (pA2=7.81±0.06). has not independently confirmed the accuracy of these methods. They are for reference only.
