JDTic (dihydrochloride) is a potent antagonist of kappa-opioid receptors (KOR) , blocking the κ-agonist U50, 488-induced antinociception. In Vivo JDTic (2.5-16 mg/kg, s.c.) dose-dependently blocks the antinociceptive response of nicotine in the tail-flick test but has no effect in the hot-plate assay or body temperature assessments at any dose tested in the mice injected with nicotine . JDTic (3 mg/kg, i.p.) is capable of reversing anxiety-like behavior in the rat model of hangover anxiety. JDTic (10 mg/kg, i.p.) decreases alcohol self-administration, suppresses cue-induced reinstatement of alcohol seeking, and specifically blocks the effects of a KOR agonist at the 2 h pretreatment time point. JDTic (30 mg/kg, i.g.) significantly blockes U50,488-induced diuresis immediately in rats. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
