Allylprodine is an opioid analgesic that is an analogue of prodine. It was discovered in by Hoffman-La Roche in 1957 during research into the related drug pethidine. Derivatives were tested to prove the theory that phenolic & non-phenolic opioids bind at different sites of the opiate receptor.
Allylprodine is more potent as an analgesic (the 3R,4S isomer is 23 times more potent than morphine) than similar drugs such as α-prodine, due to the allyl group binding to an additional amino acid target in the binding site on the μ-opioid receptor. It is also stereoselective, with one isomer being much more active.
Allylprodine produces similar effects to other opioids, such as analgesia and sedation, along with side effects such as nausea, itching, vomiting and respiratory depression which may be harmful or fatal.
Preparation of this important intermediate is detailed in the attached citation.
This compound is also known to have been made and to have existed. It has happened before.
This compound was tested on rats and found to produce profound analgesia at 8 mg/kg. It produced a 4-aminoantipyrine (Ampyrone) type analgesia at 4 mg/kg, ataxia at 10 mg/kg, prostration at 20 mg/kg, and sometimes death at 40 mg/kg.
They made the 3-benzyl compounds too but these were all inactive in the tests.
