Sample Use Guides

In Vivo Use Guide
On a black market, parafluorofentanyl is distributed in form of capsules and tablets containing the drug in the range of 33.8-408.7 ug. In preclinical studies parafluorofentanyl was administered to rats subcutaneously.
Route of Administration: Other
In Vitro Use Guide
The potency of parafluorofentanyl with respect to cloned hMOR was investigated using the heterologous expression in X. laevis. Receptor subtype was individually coexpressed with GIRK1/GIRK2 channels and RGS4, mimicking the native neuronal G protein-mediated pathway of K1 channel activation. The two-microelectrode voltage-clamp technique was then used to measure the opioid receptor-activated GIRK1/GIRK2 channel response as the increase of the inward K1 current at 270 mV, evoked by the application of increasing concentrations of opioid ligands. Parafluorofentanyl activated hMOR with EC50 of 4.2 nM.

PRIMARY Parafluorofentanyl (4-Fluorofentanyl) is an opioid analgesic being an analogue of fentanyl developed by Janssen Pharmaceutica in the 1960s. 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.
