Abstract

This paper surveys the relationships between the chemical structures and pharmacological activities of natural or semisynthetic 4,5a­ epoxymorphinans, synthetic morphinans and benzomorphans. Substitution . of the N-methyl group affords strong analgesics, opioid antagonists and mixed agonist-antagonists respectively. The role of opioid agonists and antagonists in the development of opioid receJ:>tor models is also discussed.
