Chemical Name:(2S,4aR,6aR,7R,9S,10aS,10bR)-9-(Acetyloxy)-2-(3-furanyl
)dodecahydro-6a,10b-dimethyl-4,10-dioxo-2H-naphtho[2,1-
c]pyran-7-carboxylic acid methyl ester
Biological Activity:
Potent naturally occuring non-nitrogenous κ-opioid
selective agonist that displays high affinity at both native (Ki =
4.3 nM) and cloned (Ki = 16 nM) κ-opioid
receptors. Also exhibits allosteric modulation of μ-opioid
receptor binding. Reported to be brain-penetrant and displays psychoactive
properties.
