New Salvinorin Analog

[RoboCop]

There was recently a new Salvinorin A analog made that is seven times as potent as Salvinorin A. Here is a small article on it.

Abstract
Salvinorin A is the most potent naturally occurring opioid agonist yet discovered with high selectivity and affinity for ê-opioid receptor. To explore its structure and activity relationships, a series of salvinorin A derivatives modified at the C(2) position were prepared and studied. These salvinorin A derivatives were screened for binding and functional activities at the human ê-opioid receptor. Compound 4, containing a methoxymethyl group at the 2-position, was a full ê-agonist with an EC50 value at 0.6 nM, which is about 7 times more potent than salvinorin A.

I cant imagine what the effects would be from a substance 7 times more potent than Salvinorin A! - I think I'd let my mate go first

^ LOL

But seriously I guess this is pretty good news

interesting to say the least.. i wonder if it has better bio-availability orally.. that would be quite interesting compound then. Although i can easily see "salvia on blotters" signs here and soon they would be banned.
