Biological Data

Biological description

Salvinorin B (SALB) is a pharmacologically inert ligand that potently and selectively activates the KORD (the κ-opioid designer receptor (DREADD)) (EC50 = 11.8 nM).

Salvinorin B (SALB) is ~100-fold selective for the KORD DREADD over human κ opioid receptor and other targets and shows good CNS penetrability.

Activation of KORD by Salvinorin B (SALB) induces neuronal inhibition and modifies behaviour in vivo.

Salvinorin B (SALB) can be used in mice also expressing Clozapine N-Oxide (CNO) responsive DREADDS, to allow bi-directional manipulation of neural circuits.

CNO dihydrochloride (water soluble), Clozapine N-oxide (CNO) freebase, Compound 21 and perlapine freebase also available.

Solubility & Handling

Storage instructions -20°C
Solubility overview Soluble in DMSO (20 mM)

  • This compound is light sensitive; we therefore recommend protecting the solid and solutions from exposure to light.
  • Salvinorin B (SalB) is unstable in solution and we recommend that solutions are stored at -20°C and used within 24 hours.
