Salvia divinorum (Salvia) is an increasingly popular recreational drug amongst adolescents and young adults. Its primary active ingredient, Salvinorin A (SA)-a highly selective agonist at the κ opiate receptor-is believed to be one of the most potent naturally occurring hallucinogens. However, there is little experimental data on the effects of SA in humans. In a 3-day, double-blind,...

In patients, ketamine is a fast-acting antidepressant that can induce long-lasting symptom relief. Similar rapid effects have been reported in rodents, but reports of lasting effects are limited. We sought to extend past findings by examining dose-response curves that overlap with the individual doses previously reported to induce lasting effects in rodents and determining whether effects...

Salvinorin A (SA) is a highly selective kappa opioid receptor agonist and the putative psychoactive compound in Salvia divinorum (SD), an increasingly abused hallucinogenic plant. The objectives of this study were to characterize the physiological and subjective effects of SA versus placebo and measure drug and metabolite levels. Sublingual SA doses up to 4 mg were administered in dimethyl...

Disruptions in perception and cognition are characteristic of psychiatric conditions such as schizophrenia. Studies of pharmacological agents that alter perception and cognition in humans might provide a better understanding of the brain substrates of these complex processes. One way to study these states in rodents is with tests that require attention and visual perception for correct...

Salvinorin A (SA) is a potent kappa opioid agonist with a brief duration of action. Consistent with this, our previous positron emission tomography (PET) studies of carbon-11 labeled SA showed that brain levels decrease rapidly after intravenous administration. SA is rapidly metabolized, giving the much less potent salvinorin B (SB), which is presumed to be responsible in part for SA's brief...

Stress and chronic exposure to drugs of abuse can trigger addictive and depressive disorders. Both stimuli increase activity of dynorphin, a neuropeptide that acts at kappa-opioid receptors (KORs). In humans, KOR agonists cause dysphoria, raising the possibility that dynorphin modulates the depressive-like effects of stress and chronic drug use. We examined if KOR activation alters sensitivity...

Bioactivity-guided fractionation of the leaves of Salvia divinorum has resulted in the isolation of three new neoclerodane diterpenoids: divinatorin D (1), divinatorin E (2), and salvinorin G (3), together with 10 known terpenoids, divinatorin C (4), hardwickiic acid (5), salvinorin-A (6), -B (7), -C (8), -D (9), -E (10), and -F (11), presqualene alcohol (12), and (E)-phytol (13). The...
