A study on the mechanism of the interaction between strychnine and thebaine.

open access: yes, 1972
Although strychnine and thebaine have very similar convulsant actions, mixtures of the two drugs were found to interact infra-additively in intact mice.

Alternative methods for the MnO2 oxidation of codeine methyl ether to thebaine utilizing ionic liquids

open access: yes, 2001
The MnO2 oxidation of codeine methyl ether, CME, to thebaine has been accomplished via the use of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate, bmimBF4.

N-Demethylation and N-oxidation of thebaine, an isoquinoline alkaloid by Mucor piriformis

open access: yes, 2000
Northebaine was identified as the major metabolite formed during the biotransformation of thebaine by Mucor piriformis. Minor metabolites identified are isomeric thebaine N-oxides.

Some biphenyls derived from thebaine

open access: yes, 1967
(+)-3,4-Dimethoxy-2-(5-methoxy-2-vinylphenyl)-stilbene has been prepared from thebaine. This is a biphenyl with a "buttressed" ortho-me thoxyl group, as well as being substituted in the 6,6-positions by vinyl groups.

Synthesis of thebaine in engineered S. cerevisiae.

open access: yes, 2015
Synthesis of thebaine from cell feeding assays at pH 7.5, 8, 8.5 or 9 and supplemented with (a) 100 μM (R)-reticuline or (b) 100 μM salutaridine. Strain GCY368 was used in all cell feeding assays. Error bars represent standard deviations of n = 3.
