Biological Activity for Salvinorin B

Salvinorin B is a 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.

Great version that works reliably.
By 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.
