The 5-(3-hydroxy)phenylmorphan structural class of compounds are unlike the classical morphinans, 4,5-epoxymorphinans, and 6,7-benzomorphans, in that they have an equatorially oriented aromatic ring rather than the axial orientation of that ring found in

The first synthesis of 3-deoxyoripavine and its utilization in the preparation of 10-deoxyaporphines and cyprodime [PDF]
The synthesis of 3-deoxyoripavine (7) was realized as a novel and promising intermediate towards the synthesis of the important class of dopaminergic and/or serotonergic 10- deoxyaporphines and the special pharmacological tool µ opioid antagonist ...

Carfentanil is a β‐arrestin‐biased agonist at the μ opioid receptor
Abstract Background and Purpose The illicit use of fentanyl‐like drugs (fentanyls), which are μ opioid receptor agonists, and the many overdose deaths that result, has become a major problem. Fentanyls are very potent in vivo, leading to respiratory depression and death.

Design and synthesis of quinolinopropellane derivatives with selective δ opioid receptor agonism [PDF]
Indolopropellane 2 was reported to show almost no binding affinity to the δ opioid receptor (DOR) in spite of the fact that 2 has both the propellane fundamental skeleton (message part) with binding ability to the opioid receptors and a possible DOR ...

The recent crystal structure of the κ-opioid receptor (κ-OR) revealed, unexpectedly, that the antagonist JDTic is a bivalent ligand: in addition to the orthosteric pocket occupied by morphinans, JDTic also occupies a distinct (allotopic) pocket ...
