S-Arachidonoyl-2-thioglycerol synthesis and use for fluorimetric and colorimetric assays of monoacylglycerol lipase
摘要:
We report the first synthesis of 2-thioglycerol and S-arachidonoyl-2-thioglycerol (the thioester analog of the endocannabinoid 2-arachidonoylglycerol) in an eight or nine step procedure with a yield of similar to 25% and establish the use of this substrate for maleimide-based fluorescent and dithiobis(2-nitrobenzoic acid)-based colorimetric assays of human recombinant monoacylglycerol (MAG) lipase (hMAGL) and human brain membrane MAG hydrolase activity. Inhibitor structure-activity relationships observed here for hMAGL and 2-ATG correlate well (r(2) = 0.93, n = 9) with earlier findings for mouse brain MAG hydrolase with non-thiol substrates.

The diol precursor (R)-3 of the insect growth regulator 2 was synthesized enantioselectively by two different routes: a) via enantioselective hydrogenation of the alpha-hydroxy-ketone 4, catalyzed by a Ru-BINAP-catalyst and b) via resolution of the enantiomers of glycerol using (-)-camphor-10-sulfonamide 7 as chiral auxiliary.
