特徴

• Nalfurafine is a κ-opioid receptor (KOR) agonist (EC50 = 0.05nM for human receptors expressed in CHO cell membranes).1 It is selective for κ-opioid over μ- and δ-opioid receptors (EC50s = 0.72 and 74.1nM, respectively). Nalfurafine (≥30ug/kg) reduces scratching behavior induced by chloroquine in mice, as well as locomotor activity when administered at a dose of 100ug/kg.2 In rats, nalfurafine (≥0.01mg/kg) reduces intracranial self-stimulation, lactic acid-induced stretching behavior, and scratching behavior induced by intradermal administration of serotonin .3 Nalfurafine is also an orexin 1 receptor (OX1R) antagonist (Ki = 250nM).4
