Herkinorin is an opioid analgesic that is an analogue of the natural product Salvinorin A. Unlike Salvinorin A which is a selective κ-opioid agonist with no significant μ-opioid receptor affinity, herkinorin is a μ-opioid agonist with more than 100x higher μ-opioid affinity and 50x lower κ-opioid affinity compared to Salvinorin A. Herkinorin is a semi-synthetic compound, made from Salvinorin B, which is most conveniently made from Salvinorin A by deacetylation, as while both Salvinorin A and Salvinorin B are found in the plant Salvia divinorum, Salvinorin A is present in larger quantities.
