Previous studies have attributed the prominent analgesic, hallucinogenic, sedative, and anxiolytic properties of Salvia divinorum to Salvinorin A. However, the overall pharmacological profile of this isolate limits its clinical applications. To address these limitations, our study evaluates the C(22)-fused-heteroaromatic analogue of salvinorin A [2-O-salvinorin B benzofuran-2-carboxylate]...

Over the years, pain has contributed to low life quality, poor health, and economic loss. Opioids are very effective analgesic drugs for treating mild, moderate, or severe pain. Therapeutic application of opioids has been limited by short and long-term side effects. These side effects and opioid-overuse crisis has intensified interest in the search for new molecular targets and drugs. The...

The increasing cases of depression has made the searches for new drugs and understanding of the underligning neurobiology of this psychiatric disorder a necessity. Here, we modified the structure of salvinorin A (a known halucinogen) and investigated antidepressant-like activity of its four derivatives; 22-methylsulfanylsalvinorin A(SA1), 2-O-cinnamoylsalvinorin B (CSB), 22-azidosalvinorin A...

The neoclerodane diterpenoid salvinorin A is a major secondary metabolite isolated from the psychoactive plant Salvia divinorum. Salvinorin A has been shown to have high affinity and selectivity for the κ-opioid receptor (KOR). To study the ligand-receptor interactions that occur between salvinorin A and the KOR, a new series of salvinorin A derivatives bearing potentially reactive Michael...

Salvia divinorum--a species traditionally cultivated in Oaxaca, Mexico--possesses hallucinogenic properties. It is legally recognized as a controlled substance and prohibited in many countries. The proper identification of the plant, both in fresh and dried forms, is an important issue in crime-prevention campaigns. This paper provides a thorough anatomical description of leaves, petioles, and...

Consumer use of botanicals has increased despite, in many instances, the paucity of research demonstrating efficacy or identifying liabilities. This research employed the place preference/aversion paradigm to characterize the psychoactive properties of Salvia divinorum extract (10, 30, 100mg/kg), salvinorin A (0.1, 0.3, 1.0mg/kg), Mitragyna speciosa MeOH extract (50, 100, 300 mg/kg), Mitragyna...

Salvinorin A, the active ingredient of the hallucinogenic plant Salvia divinorum is the most potent known naturally occurring hallucinogen and is a selective κ-opioid receptor agonist. To better understand the ligand-receptor interactions, a series of dicarboxylic ester-type of salvinorin A derivatives were synthesized and evaluated for their binding affinity at κ-, δ- and μ-opioid receptors....

The hallucinogenic compound, salvinorin A, is a potent κ-opioid receptor (KOR) agonist. However, other target(s) than the KOR, such as the cannabinoid CB1 receptor, have been proposed to explain its multiple pharmacological actions. Here, we have evaluated the effect of salvinorin A in lipopolysaccharide (LPS)-stimulated macrophages as well as in models of inflammation in vivo. Salvinorin A...

Extraction of fresh Salvia divinorum leaves afforded salvinorins E and D as potential biosynthesis precursors of salvinorin A, a major metabolite and a potent hallucinogen. Attempts at HPLC purification of salvinorin E (2) with acetonitrile as a solvent revealed an equilibrium with its regioisomer, salvinorin D (3), in a 3:5 ratio. The presence of both compounds was readily observed in the (1)H...

Microbial transformation of natural products is a well established model for mammalian metabolism. Salvinorin A, a diterpenoid isolated from the hallucinogenic mint Salvia divinorum Epling & Játiva-M (Lamiaceae), is a potent non-nitrogenous κ-opioid receptor agonist. The metabolism of salvinorin A has still not yet been well established. Thirty fungal species were screened for the ability to...

Salvinorin A, the most potent naturally occurring hallucinogen, has attracted an increasing amount of attention since the kappa-opioid receptor (KOR) was identified as its principal molecular target by us [Roth, B. L., et al. (2002) Proc. Natl. Acad. Sci. U.S.A. 99, 11934-11939]. Here we report the design, synthesis, and biochemical characterization of novel, irreversible, salvinorin A-derived...

Salvinorin A, the active component of the hallucinogenic herb Salvia divinorum, inhibits intestinal motility through activation of kappa-opioid receptors (KORs). However, this compound may have target(s) other than the KORs in the inflamed gut. Because intestinal inflammation upregulates cannabinoid receptors and endogenous cannabinoids, in the present study we investigated the possible...

The hallucinogenic plant Salvia divinorum has been used for medical treatments of gastrointestinal disorders. Here, we evaluated the effect of a standardized extract from the leaves of Salvia divinorum (SDE) and of its active ingredient salvinorin A on motility in vivo, both in physiological states and during croton oil-induced intestinal inflammation. SDE (1-100 mg kg(-1)) significantly...

Salvinorin A, a neoclerodane diterpenoid, isolated from the Mexican hallucinogenic plant Salvia divinorum, is a potent kappa-opioid receptor agonist. Its biosynthetic route was studied by NMR and HR-ESI-MS analysis of the products of the incorporation of [1-(13)C]-glucose, [Me-(13)C]-methionine, and [1-(13)C;3,4-(2)H2]-1-deoxy-D-xylulose into its structure. While the use of cuttings and...

The complete assignments of the (1)H and (13)C NMR spectra of the hallucinogenic neoclerodane diterpenoid salvinorin A were determined in three different NMR solvents using HSQC, HMBC and COSY. Solvent systems are described that allow the resolution of all (1)H signals. Virtual coupling was observed for the protons at C-2, C-3 and C-4 in the 600 MHz (1)H spectrum in CDCl(3). The complete...

Salvia divinorum is a widespread hallucinogenic herb traditionally employed for divination, as well as a medicament for several disorders including disturbances of gastrointestinal motility. In the present study we evaluated the effect of a standardized extract from the leaves of S. divinorum (SDE) on enteric cholinergic transmission in the guinea-pig ileum. SDE reduced electrically evoked...

Salvinorin A is a naturally occurring hallucinogenic diterpenoid from the plant Salvia divinorumthat selectively and potently activates kappa-opioid receptors (KORs). Salvinorin A is unique in that it is the only known lipid-like molecule that selectively and potently activates a G-protein coupled receptor (GPCR), which has as its endogenous agonist a peptide; salvinorin A is also the only...

The diterpene salvinorin A from Salvia divinorum has recently been reported to be a high-affinity and selective kappa-opioid receptor agonist (Roth et al., 2002). Salvinorin A and selected derivatives were found to be potent and efficacious agonists in several measures of agonist activity using cloned human kappa-opioid receptors expressed in human embryonic kidney-293 cells. Thus, salvinorin...
