Differential helical orientations among related G protein-coupled receptors provide a novel mechanism for selectivity. Studies with salvinorin A and the kappa-opioid receptor.

The Journal of biological chemistry February 2, 2007 Timothy A Vortherms, Philip D Mosier, Richard B Westkaemper et al. 40 citations

Salvinorin A, the active component of the hallucinogenic sage Salvia divinorum, is an apparently selective and highly potent kappa-opioid receptor (KOR) agonist. Salvinorin A is unique among ligands for peptidergic G protein-coupled receptors in being nonnitrogenous and lipid-like in character. To examine the molecular basis for the subtype-selective binding of salvinorin A, we utilized an...

Salvinorin A: from natural product to human therapeutics.

Molecular interventions October 1, 2006 Timothy A Vortherms, Bryan L. Roth 91 citations

The hallucinogenic plant Salvia divinorum (i.e., "magic mint") is a member of the Sage family that has been used for divination and shamanism by the Mazatecs. Over the past decade or so, S. divinorum has been increasingly used recreationally. The neoclerodane diterpene salvinorin A is the active component of S. divinorum, and recently, the kappa opioid receptor (KOR) has been identified, in...

Identification of the molecular mechanisms by which the diterpenoid salvinorin A binds to kappa-opioid receptors.

Biochemistry June 21, 2005 Feng Yan, Philip D Mosier, Richard B Westkaemper et al. 91 citations

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...
