Salvinorin B methoxymethyl ether (2-O-methoxymethylsalvinorin B) is a semi-synthetic analogue of the natural product salvinorin A which is used in scientific research.[1][2] It has a longer duration of action of around 2–3 hours, compared to less than 30 minutes for salvinorin A,[3] and has increased affinity and potency at the κ-opioid receptor. Like the related compound herkinorin, salvinorin B methoxymethyl ether is made from salvinorin B, which is most conveniently made from salvinorin A by deacetylation,[4] as while both salvinorin A and salvinorin B are found in the plant Salvia divinorum, salvinorin A is present in larger quantities.[5]

Salvinorin B methoxymethyl ether has a Ki of 0.60 nM at the κ opioid receptor,[6] and is around five times more potent than salvinorin A in animal studies, although it is still only half as potent as its stronger homolog salvinorin B ethoxymethyl ether.[7]
