Spiradoline
Spiradoline (U-62066), an arylacetamide, is a selective kappa opioid receptor (KOR) agonist with a Ki of 8.6 nM in guinea pig. The Ki values of Spiradoline for μ and δ receptors are 252 nM and 9400 nM, respectively. Spiradoline has potent diuretic, analgesic, antiarrythmic, antitussive, neuroprotective properties and easily penetrates the blood-brain barrier[1][2].
