Acrylfentanyl (also known as acryloylfentanyl or Egyptenyl) is a highly potent opioid analgesic that is an analog of fentanyl and has been sold online as a designer drug. In animal studies the IC50 or half maximal inhibitory concentration for acrylfentanyl to displace naloxone is 1.4 nM, being slightly more potent than fentanyl itself (1.6 nM) as well as having a longer duration of action.
Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.
As acrylamide derivatives are often used in drug discovery to make covalent inhibitors which will bind irreversibly to its target, acrylfentanyl is claimed to be naloxone resistant. However, acute intoxications with acrylfentanyl on mice threatened by naloxone (2 mg/kg) have shown that acrylfentanyl could be displaced from the opioid receptor.
Life-threatening adverse reactions caused by furanylfentanyl use have been observed in Sweden and Canada.At least seven deaths in Cook County, Illinois, have been linked to furanylfentanyl in 2016, with additional deaths in suburban Chicago in 2017
Furanylfentanyl may be measured in blood or urine to monitor for abuse, confirm a diagnosis of poisoning, or assist in a medicolegal death investigation. Commercially available immunoassays are often used as initial screening tests, but chromatographic techniques are generally used for confirmation and quantitation. Blood furanylfentanyl concentrations are expected to be in a range of 1-45 μg/L in victims of fatal overdosage.
Butyrfentanyl binds to the opioid receptor. During the studies of in vitro inhibition of specific [3H] fentanyl binding to the opioid receptor, the order of analogues was: (±)-cis-3-methylfentanyl > fentanyl = alpha-methylfentanyl > butyrylfentanyl > benzylfentanyl. The studies in inhibition studies on binding affinity achieved the same order of analogues. It means that butyrfentantyl is a less potent opioid-agonist than fentanyl. On the other side, during in vitro studies of cross-reactivity with the fentanyl antibody between fentanyl and the fentanyl analogs examined, revealed order: fentanyl = butyrylfentanyl > (±)-cis-3-methylfentanyl > benzylfentanyl > alpha-methylfentanyl. High cross-reactivity may be the effect of the shape of the molecule – the shape of butyrfentanyl is closest to the original fentanyl molecule, which makes it easy to bind by fentanyl antibodies.
