oripavine
Oripavine is an opioid alkaloid of the morphinan class that occurs naturally in the opium poppy (Papaver somniferum) in trace amounts. It is closely related to other opium alkaloids such as morphine and thebaine and shares the characteristic morphinan skeleton with the usual three-dimensional features of this chemical family.
In raw opium, oripavine is typically present at much lower levels than morphine or thebaine and is
Chemically, oripavine is a derivative of the morphinan framework and differs from morphine by specific substituents
Pharmacologically, oripavine acts on opioid receptors and exhibits effects characteristic of morphinan alkaloids, including analgesic and
As a chemical precursor, oripavine derivatives have been used in the synthesis of other semi-synthetic opioids.
Legally, oripavine is a controlled substance in many jurisdictions and is regulated under national narcotics laws
