Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."
This is a list of fentanyl analogues (sometimes referred to as Fentalogs), [1] [2] [3] including both compounds developed by pharmaceutical companies for legitimate medical use, and those which have been sold as designer drugs and reported to national drug control agencies such as the DEA, or transnational agencies such as the EMCDDA and UNODC.
Synthetic opioids, primarily fentanyl, were involved in about two-thirds of those deaths. But overdose deaths started a rapid decline at the start of last year. Fentanyl is still involved in most ...
Meperidine is a fully synthetic opioid, and other members of the phenylpiperidine family like alfentanil and sufentanil are complex versions of this structure. [71] Like other opioids, fentanyl is a weak base that is highly lipid-soluble, protein-bound, and protonated at physiological pH. [71]
The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
Fentanyl is a synthetic opioid about 50 times more powerful than heroin and 100 times more powerful than morphine. Opioids accounted for about 82,000 U.S. deaths in 2022, ten times the number in ...
A new type of non-opioid painkiller, aimed at treating short-term pain in adults, has been approved by the US Food and Drug Administration (FDA). The drug suzetrigine, known by its brand name ...
