An enkephalin analogue coupled to 'aminofentanyl' has been synthesized and tested for biological activities at the mu and delta opioid receptors. Aminofentanyl which represents a structural derivative of fentanyl has been synthesized by acylation of 1-(2-phenethyl)-4-(N-anilino)piperidine with phthaloyl protected beta-alaninyl chloride in the presence of DIPEA, followed by deprotection with hydrazine hydrate. Aminofentanyl has also been successfully acylated with ethyl isocyanate, various acid anhydrides, to further investigate structure-activity relationships of these new fentanyl derivatives. Among the new derivatives compound 7 which carries a Tyr-D-Ala-Gly-Phe opioid message sequence showed good opioid affinity (1 nM at both delta and mu opioid receptors) and bioactivity (34.9 nM in MVD and 42 nM in GPI/LMMP bioassays).

D005283 Fentanyl A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance.

D017450 Receptors, Opioid, mu A class of opioid receptors recognized by its pharmacological profile. Mu opioid receptors bind, in decreasing order of affinity, endorphins, dynorphins, met-enkephalin, and leu-enkephalin. They have also been shown to be molecular receptors for morphine.
