Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."

Pantopon, also known as Opium Alkaloids Hydrochlorides, is a preparation of opiates made up of all of the alkaloids present in opium in their natural proportions as hydrochlorides salts. [ 1 ] [ 2 ] [ 3 ] It can sometimes be tolerated by people who are allergic to morphine .

In a study of dosage used on beagle dogs, the first sign of nausea was observed at as little of a dose of 0.5 mg/kg and occurred within a 2.5 hour span. The effective dose to induce emesis in the dogs was seen to be 2.0 mg/kg and lasted no longer than 2.5 hours after administration. [11]
Opiates are alkaloid compounds naturally found in the Papaver somniferum plant (opium poppy). The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions with evidence of opiate trade and use for pain relief as early as the eighth century AD.
This alkaloid is biosynthetically related to salutaridine, oripavine, morphine and reticuline. [6] In 2012 there was an amounted 146,000 kilograms of thebaine produced. [7] In 2013, Australia was the main producer of poppy straw rich in thebaine, followed by Spain and then France. By 2017, worldwide thebaine production dropped to 2,008 kg. [8]
Opium poppy contains at least 50 different alkaloids, but most of them are of very low concentration. Morphine is the principal alkaloid in raw opium and constitutes roughly 8–19% of opium by dry weight (depending on growing conditions). [84] Some purpose-developed strains of poppy now produce opium that is up to 26% morphine by weight.
Morphine. Synthesis of morphine-like alkaloids in chemistry describes the total synthesis of the natural morphinan class of alkaloids that includes codeine, morphine, oripavine, and thebaine and the closely related semisynthetic analogs methorphan, buprenorphine, hydromorphone, hydrocodone, isocodeine, naltrexone, nalbuphine, oxymorphone, oxycodone, and naloxone.
