Submit ReviewSalvinorin B
Description: Activator of κ-opioid DREADD (KORD)
Chemical Name: (2S,4aR,6aR,7R,9S,10aS,10bR)-2-(3-Furanyl)dodecahydro-9-hydroxy-6a,10b-dimethyl-4,10-dioxo-2H-naphtho[2,1-c]pyran-7-carboxylic acid methyl ester
Purity: ≥98% (HPLC)
Biological Activity
Potent and selective κ-opioid DREADD (KORD) activator (EC50 = 11.8 nM). Selective for KORD over endogenous κ opioid receptor and a range of other related targets. Exhibits no analgesic or ataxic effects in wild type mice. Induces neuronal hyperpolarization, and modifies locomotor activity and feeding behavior in KORD-expressing mouse models. Brain penetrant. Metabolite of salvinorin A (Cat. No. 2134).

Melanie Pina on 12/22/2019
Assay Type: Ex Vivo
Species: Human
Cell Line/Tissue: neuron
Great version that is easily dissolved in DMSO. Worked well in slice electrophysiology and produced reliable hyperpolarization in neurons expressing KOR DREADD at 100 nM.

Allosteric GPCR Pharmacology Poster
G protein-coupled receptors (GPCRs) are intrinsically allosteric proteins. This poster provides insights into allosteric mechanisms of GPCR biology, highlighting key facets of GPCR allostery and therapeutic applications of allosteric modulators.
GPCR Efficacy and Biased Agonism Poster
GPCRs can interact with multiple distinct transducers or regulatory proteins and these can be preferentially engaged in an agonist-specific manner giving rise to biased agonism. This poster discusses cutting edge GPCR signaling pharmacology and highlights therapeutic applications of biased agonism.
