Norfentanyl structure
Norfentanyl is an inactive synthetic opioid analgesic drug precursor. It is an analog and metabolite of fentanyl with the removal of the phenethyl moiety (or functional group) from fentanyl chemical structure. WebAs results, the study revealed that the introduction of the 3-carbomethoxy group in the piperidine structure of fentanyl shortened the duration of its action and reduced its potency. It was clarified that the carbomethoxy derivatization at the carbon in 4-position of the piperidine ring is essential to gain such high potency of about 100 times higher than that …

Fentanyl, also spelled fentanil, is a highly potent synthetic opioid primarily used as an analgesic. Since 2024, fentanyl and its analogues have been responsible for most drug overdose deaths in the United States, causing over 71,238 deaths in 2024. Because fentanyl is 50 to 100 times more potent than morphine, its primary clinical utility is in pain management for cancer patients and those reco… WebAbstract. The microsomal metabolism of fentanyl, a synthetic opioid commonly used in anesthesia, was investigated in human liver. Incubation of fentanyl with human hepatic microsomes fortified with NADPH resulted in the formation of a single major metabolite, namely norfentanyl, as determined by GC/MS. No evidence was obtained for the …
