Thebaine


Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt.A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects.At high doses, it causes convulsions similar to strychnine poisoning.

Thebaine is the predominant alkaloid of this species and in a UN-backed programme of large-scale cultivation trials were organized in various countries. High yielding strains were introduced, for example, Ayra II, a race obtained from west Iran in 1974 which gives 3.5% thebaine in the dried capsules.

Thebaine is a DEA Schedule II controlled substance. Substances in the DEA Schedule II have a high potential for abuse which may lead to severe psychological or physical dependence. Drug Enforcement Administration (DEA) Thebaine is an alkaloid opiate that is used as an intermediate in the biosynthesis of other opioids.

Dose and Modes of Administration. Buprenorphine is a synthetic thebaine derivative that has both analgesic and opioid antagonist properties. The usual dose is 0.3 mg given parenterally, 0.2-0.4 mg by the sublingual route, or the application of transdermal patches that deliver doses of 5-70 µg/h.

Thebaine is also known as paramorphine due to its stimulatory effects-as opposed to the depressant effects of Morphine and Codeine. Normally, Opium contains between 0.3% to 1.5% Thebaine (as much as 6% has been reported in some species). It is classified as a narcotic and convulsant and, as such, is an internationally regulated product. ...

Thebaine, also known as Paramorphine is a white, crystalline, slightly water-soluble (in pure form after a synthesis), poisonous alkaloid, with the molecular Formular: C 19 H 21 NO 3, present in opium in small quantities. The Thebaine-Constituent of Raw-Opium is normally between 0.2% and 1.5% But higher amounts up to 6% have also been reported.

Thebaine, a minor content of opium, is controlled in Schedule II of the Controlled Substance Act as well as under international law. Although chemically similar to both morphine and codeine, this drug produces stimulant rather than depressant effects.

Thebaine is extracted from opium poppy for use in semi-synthesis of a number of opioids. This module was added to the reticuline producing platform strain (CSY1060) as a chromosomal integration (CSY1064). The resulting strains were cultured in minimal media for 120 h and the growth media assayed for thebaine (Fig. 4A, B).

Thebaine is a naturally occurring opiate that is intro-duced into the body, along with morphine and codeine, following the consumption of poppy seeds.4-8 Scientific literature has clearly demonstrated the distinct possibil-ity of a morphine and/or codeine positive due to poppy seed consumption.4-8 The potential legal consequences

The meaning of THEBAINE is a poisonous crystalline alkaloid C19H21NO3 found in opium in small quantities, related chemically to morphine and codeine, and possessing a sharp astringent taste and a tetanic action like strychnine.

Thebaine has also been used as a 1 mg/ml standard in methanol for urine thebaine analysis in individuals who had consumed poppy seeds. Biochem/physiol Actions. The (-)-isomer of thebaine is the naturally-occurring constituent of opium that is a precursor of morphine. It has poor antinociceptive activity and induces convulsions.

Thebaine. Thebaine is an opiate alkaloid derived from opium and is not used therapeutically. Instead, Thebaine is converted into several medications including: oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine and etorphine.

However, (-)-thebaine was more effective at the delta-opioid receptor (Ki = 1.02+/-0.01 microM) whereas (+)-thebaine was more effective at the mu-opioid receptor ( Ki = 2.75+/-0.01 microM). Opioid-induced antinociception associated with unnatural thebaine raises the possibility of additional mu- and delta-opioid receptor sites.

It is the parent compound from which a series of semi-synthetic opioids are derived, whichmorphine, codeine, and to a lesser extent thebaine has been greatly increased. In modern times, much of the thebaine, which often serves as the raw materialHydrocodone is a semisynthetic opioid, converted from codeine or less often from thebaine. Production using genetically engineered yeasts have been developed butproduce codeine, thebaine, and in some cases negligible amounts of hydromorphone, dihydromorphine, dihydrocodeine, tetrahydro-thebaine, and hydrocodonepharmaceutical industry. The third is to produce other alkaloids, mainly thebaine and oripavine, that are processed by the pharmaceutical industry into drugspsychoactive compounds found in the opium plant include morphine, codeine, and thebaine.
