Salvinorin B methoxymethyl ether
||It has been suggested that Salvinorin B ethoxymethyl ether be merged into this article. (Discuss) Proposed since May 2014.|
|Systematic (IUPAC) name|
|(2S,4aR,6aR,7R,9S,10aS,10bR)- 9-(methoxymethoxy)- 2-(3-furanyl)dodecahydro-6a,10b-dimethyl-4,10-dioxo-2H-naphtho-[2,1-c]pyran-7-carboxylic acid methyl ester|
|(what is this?)|
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. It has a longer duration of action of around 2–3 hours, compared to less than 30 minutes for salvinorin A, 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, as while both salvinorin A and salvinorin B are found in the plant Salvia divinorum, salvinorin A is present in larger quantities.
Salvinorin B methoxymethyl ether has a Ki of 0.60 nM at the κ opioid receptor, and is around 5x more potent than Salvinorin A in animal studies, although it is still only half as potent as its stronger homologue Salvinorin B ethoxymethyl ether.
