Biological Activity

Nalfurafine hydrochloride (TRK-820 hydrochloride) is a potent selective and orally active kappa opioid receptor (KOR) agonist. Nalfurafine hydrochloride (TRK-820 hydrochloride) enhances the therapeutic potential of MOR-targeting analgesics.

A single administration of subcutaneous TRK-820 significantly increased spontaneous ipsilateral rotational behavior of hemi-parkinsonian rats at 30 μg/kg though the efficacy is moderate and also significantly inhibited L-DOPA-induced dyskinesia at 10 and 30 μg/kg; this inhibition is reversed in the presence of nor-binaltorphimine, a kappa opioid receptor antagonist. TRK-820 dose-dependently inhibited phencyclidine-induced rat hyperlocomotion. TRK-820 dose-dependently attenuated the biochemical changes of both dopamine and serotonin in the prefrontal cortex of rats treated with phencyclidine without affecting their basal levels in normal rats.
