生化／生理作用
Meptazinol entered the human pharmaceutical market as a racemic mixture in the 1980s for use as an analgesic. Its pharmacology is not completely understood; however, its analgesic properties are mostly due to its partial agonism at the mu1 opioid receptor. Due to its partial agonism, Meptazinol antagonizes morphine dependence in vivo. Its advantage over other opiates is its reduced capacity to cause addition and respiratory depression, also due to its intrinsic activity as a partial agonist. Meptazinol has been found to have additional activity as an acetylcholinesterase (AChE) inhibitor, particularly in its (-) enantiomeric form, which may partially explain its analgesic properties. AChE inhibitors are used to treat Alzheimer′s disease, providing additional interest in this compound.

Molecular docking has been performed to investigate the binding mode of (-)-meptazinol (MEP) with acetylcholinesterase (AChE) and to screen bis-meptazinol (bis-MEP) derivatives for preferable synthetic candidates virtually. A reliable and practical docking method for investigation of AChE ligands was established

To investigate the mechanism of action of a potent analgesic, (+/-)-meptazinol. The structures of meptazinol enantiomers were compared with opioid pharmacophore and tramadol. Neither enantiomer of meptazinol fitted any patterns among the opioid pharmacophore and tramadol, although they did share
