Salvinorin

Salvinorins are a group of natural chemical compounds and their structural analogs. Several salvinorins have been isolated from Salvia divinorum. They are classified as diterpenoid furanolactones. Salvinorin A is a hallucinogen with dissociative effects.

Several salvinorins have been isolated and characterized.

Associated compounds

In search for useful biological activity, several synthetic and semi-synthetic analogs have been prepared for study. Semi-synthetic analogs include salvinorin B ethoxymethyl ether and salvinorin B methoxymethyl ether. Fully synthetic analogs include herkinorin.

Several derivates can be conveniently made from salvinorin B. Most derivatives are selective kappa opioid agonists as with salvinorin A, although some are even more potent, with the most potent compound 2-ethoxymethyl salvinorin B being ten times stronger than salvinorin A. Some derivatives, such as herkinorin, reduce kappa opioid action and instead act as mu opioid agonists.[1][2][3][4]

22-Thiocyanato-salvinorin A is notable because of its functional selectivity.[5] 2-Methoxymethyl Salvinorin B is seven times more potent than Salvinorin A at KOPr in GTP-γS assays.[6]

Many other terpenoids have been isolated from Salvia divinorum, including classes named divinatorins and salvinicins. None of these compounds have shown significant (sub-micromolar) affinity at the kappa-opioid receptor, and there is no evidence that they contribute to the plant's psychoactivity.[7][8]

gollark: Preprogram your shop with the prices and locations of other shops (or I guess have it communicate with others over some defined interface), and when it runs low have it try and buy more stock from elsewhere and send drones to collect.
gollark: Hmm. Drones can fly around other people's claims *and* suck up items...
gollark: Make a shop which buys and sells items in one more unified system, and which adjusts buy/sell prices automatically based on how much it has. Maybe it could even communicate with other people's stores to figure out demand for some products.
gollark: Now sell them cheaper than Wojbie (Woodjbie?) does.
gollark: brb checking storage for 28 logs
