 UNODC - Bulletin on Narcotics - 1950 Issue 2 - 003
Codeine itself is oxidized into codeinone, and the methyl ether of the enol form of this is the same as thebaine.
Moreover, since the action of acetic anhydride on codeinone makes it possible to isolate 3-methoxy-4:6 dihydroxyphenanthrene,[16] the respective positions of the phenol group and of the alcoholic hydroxyl must clearly be 3 and 6.
The constitution of these phenanthrene derivatives (morphol,[17] morphenol, thebaol,[18] etc.) was explained by Pschorr, who pioneered in the field of phenanthrene synthesis and succeeded in synthesizing the substitute phenanthrenes which have made it possible to identify by direct comparison most of the products of degradation of the morphine alkaloids.

 Patent 4054566: Process for converting neopinone to codeinone
Since codeinone can be easily converted to codeine by reducing the ketone group of codeinone to a hydroxyl group, a procedure for converting neopinone to codeinone would be an advancement in the art.
When a mixture containing neopinone and codeinone is employed it is generally a mixture containing any portion of codeinone from about 1% to about 99% by weight and from about 99% to about 1% neopinone by weight based on the total weight of the mixture.

 Cell death-inducing activity of opiates in human oral tumor cell lines.
A study of structurally-related compounds suggested that the alpha,beta-unsaturated ketone group of codeinone was responsible for its antitumor cytotoxicity.
The cytotoxic activity of codeinone was significantly reduced by N-acetylcysteine, but not affected by FeCl3, CuCl2, CoCl2, sodium ascorbate or catalase.
These data suggest that codeinone induces cytotoxicity in oral tumor cell lines, possibly by a Michael-like addition of a protein SH or of an amino group to the bouble bond of codeinone.

 The Scientist :: RNAi turns poppies off morphine, Nov. 15, 2004
The enzymology of the entire morphine pathway is largely elucidated, but virtually nothing is known of what regulates the accumulation of morphine and its intermediates in poppies.
Larkin and colleagues employed RNA interference to silence codeinone reductase (COR), the penultimate enzyme in morphine biosynthesis, and shed light on pathway controls.
Larkin and colleagues suggest the unexpected reticuline phenotype may have been caused by a buildup of morphine substrates codeinone and neopinione that triggered negative feedback on one or more earlier enzymes or transport steps of the morphine branch.

 UNODC - Bulletin on Narcotics - 1958 Issue 3 - 006
Codeine can be oxidized to codeinone with potassium permanganate, and codeinone reacts with the diazo reagent to form a coloured compound.
Thebaine, as an enol ether of codeinone, can be transformed into the latter by acid hydrolysis, and undergoes the same colour reaction.
With this degree of acidity, the codeinone already present at the beginning of oxidization is oxidized fast enough and the extinctions, even for minute quantities of codeine (0.04-0.2 mg) are still large enough to permit of sufficiently accurate measurement, as shown by table 7.

To establish the synthetic route to the desired precursors suitable for labelling, the apomorphine backbone was chosen as the model compound.
The synthesis started by an oxidation of codeine (1) to codeinone (2) which underwent ring-opening followed by sceletal rearrangement to give morphothebaine (3) when treated with methanesulfonic acid (Scheme 1).
After the sceletal rearrangement the nitrogen will be protected with an appropriate protecting group which can easily be removed at a late stage of the synthetic sequence.

The benzylisoquinoline alkaloids of opium poppy accumulate in the cytoplasm, or latex, of specialized laticifers that accompany vascular tissues throughout the plant.
However, immunofluorescence labeling using affinity-purified antibodies showed that three key enzymes, (S)-N-methylcoclaurine 3'-hydroxylase (CYP80B1), berberine bridge enzyme (BBE), and codeinone reductase (COR), involved in the biosynthesis of morphine and the related antimicrobial alkaloid sanguinarine, are restricted to the parietal region of sieve elements adjacent or proximal to laticifers.
The localization of laticifers was demonstrated using antibodies specific to the major latex protein (MLP), which is characteristic of the cell type.

Lysergic acid diethylamide antagonizes shaking induced in rats by five chemically different compounds.
Cowan A, Watson T. Thyrotropin-releasing hormone (TRH), sodium valproate, AF-3-5 (1-[2-hydroxyphenyl]-4-[3-nitrophenyl]-1,2,3,6-tetrahydropyrimidine-2-one), RX336-M (7,8-dihydro-5',6'-dimethylcyclohex-5'-eno-1',2',8',14 codeinone), and Sgd 8473 (alpha-[4-chlorobenzylideneamino)-oxy]-isobutyric acid) each induced repetitive shaking of the body of rats after intraperitoneal injection.
This action of the five diverse chemicals appears to be subserved by a common pharmacological component, because pretreatment with d-lysergic acid diethylamide (0.03--1.0 mg kg-1, s.c.) attenuated the shaking behavior in a dose-related manner, and cross tolerance was found between RX336-M and TRH, sodium valproate, and AG-3-5.
