A study on the mechanism of the interaction between strychnine and thebaine.
Although strychnine and thebaine have very similar convulsant actions, mixtures of the two drugs were found to interact infra-additively in intact mice.

N-Demethylation and N-oxidation of thebaine, an isoquinoline alkaloid by Mucor piriformis
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
(+)-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.
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.
