Biochem/physiol Actions

LY2444296 is a brain-penetrant, orally active, short-acting, high-affinity, potent and selective κ (kappa) opioid receptor (KOR) antagonist (human κ/μ/δ Ki = 0.565/35.8/211 nM against diprenorphine binding; GTP-γ-S binding IC50/agonist/subtype transfectant = 1.57 nM/300 nM U69593/κ, 21.3 nM/1 μM DAMGO/μ 293 nM/30 nM DPDPE/d). LY2444296 reverses κ agonist antinociceptive efficacy in vivo (ED50 = 0.24 mg/kg p.o. against 1 mg/kg U69593 sc. by rat formalin test), decreases immobility time (10 or 30 mg/kg sc.) and prevents enhanced alcohol consumption (5 mg/kg i.p.) among mice subjected to stress by forced swimming.

Arylphenylpyrrolidinylmethylphenoxybenzamides were found to have high affinity and selectivity for κ opioid receptors. On the basis of receptor binding assays in Chinese hamster ovary (CHO) cells expressing cloned human opioid receptors, (S)-3-fluoro-4-(4-((2-(3-fluorophenyl)pyrrolidin-1-yl)methyl)phenoxy)benzamide (25) had a K(i) = 0.565 nM for

The κ-opioid receptor (KOP-r) system and its endogenous ligands, the dynorphins, are involved in the neurobiological regulation of addictive states, and of mood. There are limited data on the impact of selective KOP-r antagonism in humans on basic biobehavioral functions

The recruitment of the stress circuitry contributes to a shift from positive to negative reinforcement mechanisms sustaining long-term cocaine addiction. The kappa opioid receptor (KOPr) signaling is upregulated by stress and chronic cocaine exposure. While KOPr agonists induce anhedonia and

Prototypical long-acting kappa opioid receptor (KOPR) antagonists [e.g., norbinaltorphimine (norBNI)] have been reported to exert anxiolytic-like effects in several commonly used anxiety tests in rodents including the novelty-induced hypophagia (NIH) and elevated plus maze (EPM) tests. It remains unknown if

Our laboratory has previously demonstrated that daily forced swim stress (FSS) prior to ethanol drinking sessions facilitates enhanced ethanol consumption in mice with a history of chronic intermittent ethanol (CIE) vapor exposure without altering ethanol intake in air-exposed controls. Because
