Thienorphine is a very potent, extremely long-acting, orally-active opioid analgesic with mixed agonist–antagonist properties which was developed by the Beijing Institute of Pharmacology and Toxicology as a potential treatment for opioid dependence.[1][2][3] It is a high-affinity, balanced ligand of the μ- (Ki = 0.22 nM), δ- (Ki = 0.69 nM), and κ-opioid receptors (Ki = 0.14 nM), behaving as a partial agonist of the μ- (Emax = 19%–28%) and κ-opioid receptors (Emax = 65–75%) and as an antagonist of the δ-opioid receptor.[4][5][6] It also possesses relatively low affinity for the nociceptin receptor (Ki = 36.5 nM), where it acts as an antagonist.[6]
