Background:

Adrenorphin (metorphamide) is a potent inhibitor of nicotine-induced adrenaline and noradrenaline release with IC50 value of 10 μM [1].

Adrenorphin (metorphamide) is an endogenous, C-terminally amidated, opioid octapeptide (Tyr-Gly-Gly-Phe-Met-Arg-Arg-Val-NH2) that is produced from proteolytic cleavage of proenkephalin A and is widely distributed throughout the mammalian brain [2].

Adrenorphin (metorphamide) is selective nicotine-induced adrenaline and noradrenaline release inhibitor and has higher than 100-fold more potent than the reported nicotine-induced adrenaline and noradrenaline release inhibitor Met5-enkephalin. When tested with bovine adrenal chromaffin cells, Adrenorphin (metorphamide) showed inhibition on 5 μM nicotine-induced ATP release by almost 50% at 5μM and the inhibition was not in a dose-dependent manner [1]. In bioassays and binding assays, Metorphamide exhibited high μ-binding activity, as well as κ-binding activity with nearly half percent toμ-binding activity, while showed no activity on δ-binding [2].
