Thebaine (Paramorphine)

Build a 3D molecular structure model of the opioid drug precursor Thebaine (Paramorphine) with Genuine Molymod Parts from Indigo Instruments

Thebaine or paramorpine is a morphinan type alkaloid opiate found in the opium poppy & is structurally similar to morphine & codeine. It has a four-ring system (a fused pentacyclic skeleton two methoxy (-OCH3) groups on its rings. It also has a tertiary amine (-NCH3) which contributes to its alkaloid nature. Thebaine has electron rich diene rings making it more chemically susceptible to Diels-Adler reactions.

Unlike morphine & codeine which are nervous system depressants, thebaine acts as a stimulant and is toxic in high doses. Its convulsant properties prevent its use as a painkiller but it is used as a precursor compound in the synthesis of  oxycodone, naloxone, and buprenorphine.
