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.

Kappa opioid (KOP) receptor antagonists and delta opioid (DOP) receptor agonists have antidepressant-like effects in animal tests and may be useful for treatment-resistant depression in humans. In this study, we examined whether the combination of a KOP receptor antagonist and

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.

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
