Behavioral effects of thebaine in the rhesus monkey [PDF]
Pharmacology Biochemistry and Behavior, 1981 Three experiments were conducted with rhesus monkeys to assess some behavioral effects of the opium alkaloid, thebaine, in relation to its dependence liability. The concurrent intramuscular administration of naloxone did not antagonize the rate-decreasing effects of thebaine on a fixed-ratio (FR) schedule of food-reinforced responding.

Thebaine Synthase: A New Enzyme in the Morphine Pathway in
Natural Product Communications, 2007 Along the poppy morphine biosynthetic pathway, the transition from salutaridinol-7-O-acetate to thebaine had previously been claimed to proceed non-enzymatically between pH 8–9. At pH 6–7, the acetate was transformed to an azonine derivative.
