Abstract
Salvinorin A ( 1), a neoclerodane diterpene from the hallucinogenic mint Salvia divinorum, is the only known non-nitrogenous and specific κ-opioid agonist. Several structural congeners of 1 isolated from Salvia splendens ( 2– 8) together with a series of semisynthetic derivatives ( 9– 24), some of which possess a pyrazoline structural moiety ( 9, 19– 22), have been tested for affinity at human μ, δ, and κ opioid receptors. None of these compounds showed high affinity binding to these receptors. However, 10 showed modest affinity for κ receptors suggesting that other natural neoclerodanes from different Salvia species may possess opioid affinity.
