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