Alcohol use and major depressive disorder are frequently comorbid, with individuals diagnosed with a substance use disorder being nearly three times as likely to have major depression. Poor treatment responses are found for both disorders and are further complicated when they co-occur, underscoring the need for better therapies. One potential candidate is ketamine, which has been shown to have...
Kappa opioid receptor (KOR) agonists have preclinical antipsychostimulant effects; however, adverse side effects have limited their therapeutic development. In this preclinical study, conducted in Sprague Dawley rats, B6-SJL mice, and non-human primates (NHPs), we evaluated the G-protein-biased analogue of salvinorin A (SalA), 16-bromo salvinorin A (16-BrSalA), for its anticocaine effects, side...
The kappa (κ) opioid receptor/dynorphin system modulates depression-like states and anhedonia, as well adaptations to stress and exposure to drugs of abuse. Several relatively short-acting small molecule κ-receptor antagonists have been synthesized, and their behavioral profile has been examined under some conditions. The hypothesis of this study is that pharmacological manipulations of the...
