Introduction of 351183-88-5 :

5'-Guanidinonaltrindole (5'-GNTI) hydrochloride is a highly selective and potent κ-opioid receptor antagonist with a Ki of 0.18 nM for human κ-opioid receptor[1]. 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[1].
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)[1]. In Vivo:5'-Guanidinonaltrindole (5'-GNTI) (0.03-3 mg/kg; s.c.; once) induces scratching in mice[2].
