Antagonist radiotracers have shown only a low sensitivity for detecting competition from high-efficacy agonists at opioid receptors (ORs) in vivo. We report that [11C]PEO binds with high affinity to μ and κ-opioid receptors, is a full agonist, and concentrates in brain regions of rats with a high density of the μ-OR after intravenous injection. Blocking studies with μ and κ-OR selective compounds demonstrated that the binding of [11C]PEO is saturable and selective to the μ-OR in rat brain.

The separation of thevinone (2a) and β-thevinone (2b), as well as that of dihydrothevinone (3a) and β-dihydrothevinone (3b) was accomplished. By the application of various procedures numerous new N-substituted Diprenorphine analogues (8a-f) with 7R absolute configuration were synthesized. Detailed pharmacological investigation of the prepared compounds may contribute to a better understanding of the structure-activity relationship of morphine alkaloids.
