3,4-Methylenedioxymethamphetamine (MDMA) has shown efficacy as a medication adjunct for treating post-traumatic stress disorder (PTSD). However, MDMA is also used in nonmedical contexts that pose risk for cardiovascular and neurologic complications. It is well established that MDMA exerts its effects by stimulating transporter-mediated release of the monoamines 5-hydroxytryptamine (5-HT),...

Recent clinical trials indicate favorable therapeutic outcomes of psychedelic-assisted psychotherapy for anxiety and treatment-resistant depression. Whereas the neurobiological systems underlying these effects are not well understood, animal behavioral models can serve to investigate these mechanisms. For the current study, we implemented 2 rodent models predictive of anxiolytic drug effects, a...

Recent discoveries from clinical trials with psychedelic-assisted therapy have led to a resurgence of interest in the psychopharmacology of lysergic acid diethylamide (LSD). Preclinical drug discrimination is an invaluable tool to investigate the neurochemical mechanisms underlying subjective drug effects. The current study extends previous drug discrimination research by including both sexes....

Salvinorin A, the main active component of Salvia divinorum, is a potent and selective κ opioid receptor agonist. Synthetic derivatives of this substance may be useful in the development of medicinal treatments for pain, mood disorders, and drug dependence. Such developments require extensive preclinical screening of these compounds. The drug discrimination assay is a valuable method for...

Salvia divinorum is a small perennial shrub that has gained recent popularity among the drug-using subculture as a legal alternative to hallucinogens. Salvinorin A, the main active compound found in the S.divinorum plant, is an atypical hallucinogen with pharmacological selectivity at kappa opioid (KOP) receptor sites and is a unique non-nitrogenous neoclerodane diterpene which is structurally...

Research interests regarding the psychopharmacology of salvinorin A have been motivated by the recreational use and widespread media focus on the hallucinogenic plant, Salvia divinorum. Additionally, kappa opioid (KOP) receptor ligands may have therapeutic potential in the treatment of some neuropsychiatric conditions, including drug dependence and mood disorders. Salvinorin A is a selective...

Relatively few studies have compared the discriminative stimulus effects of 3,4-methylenedioxymethamphetamine (MDMA) and cocaine, and findings from different laboratories are somewhat inconsistent. One possible reason for discrepant results may be the use of different reinforcement schedules during discrimination training. The present study compared fixed ratio (FR) 20 and variable interval...

The discriminative stimulus effects of the stereoisomers of 3,4-methylenedioxymethamphetamine (MDMA) were studied in rats trained to discriminate 1.25mg/kg of (+)-MDMA or 3.5mg/kg of (-)-MDMA from saline, in a two lever, water-reinforced, drug discrimination situation. The isomers of MDMA and 3,4-methylenedioxyamphetamine (MDA) substituted completely for both training drugs. The stimulants...
