解説
エセロリン(Eseroline)は、オピオイドアゴニストとして作用する薬剤である。アセチルコリンエステラーゼ阻害剤フィゾスチグミンの代謝物質であるが、フィゾスチグミンとは異なり、アセチルコリンエステラーゼ阻害作用は弱く、容易に逆行し、μ-オピオイド受容体に媒介されるかなり強い鎮痛剤効果を示す。
説明
Eseroline is a drug which acts as an opioid agonist. It is a metabolite of the acetylcholinesterase inhibitor physostigmine but unlike physostigmine, the acetylcholinesterase inhibition produced by eseroline is weak and easily reversible, and it produces fairly potent analgesic effects mediated through the μ-opioid receptor.
化学的特性
Physostigmine crystals or solutions, when heated, exposed to light and air, or in the presence of traces of metal, readily turn red, are more unstable to bases, and are readily hydrolyzed to eserobine, which are capable of being oxidized to red physostigmine salicylate, depriving the product of its therapeutic efficacy.
天然物の起源
Eseroline, although derived from physostigmine by hydrolysis of N-methylcarbamoil group, is also structurally related to morphine.
使用
(-)-Eseroline is a metabolite of physostigmine, displaying both anti-acetylcholinesterase and opiate agonist activities.
定義
ChEBI: Eseroline is a pyrroloindole that is 1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole substituted by methyl groups at positions 1, 3a and 8 and a hydroxy group at position 5. It is a metabolite of physostigmine and causes neuronal cell death by a mechanism involving loss of cell ATP. It has a role as an opioid analgesic and a human xenobiotic metabolite. It is a member of phenols and a pyrroloindole.
