Determination of Catechol-O-Methyltransferase Activity in Various Tissues by Liquid Chromatography

Catechol-O-methyltransferase activity was determined using liquid chromatography with amperometric detection.With dopamine as a substrate, the method allowed the individual determination of both posible product isomers in the various biological matrices investigated.The selectivity of the electrochemical detector proved advantageous in several aspects, including higher sample throughput, negligible blank values, and simplified chromatograms.The resolution of the reverse phase column permitted the incorporation of an internal standard, 3-methoxy-4-hydroxybenzylamine,to improve the precision to less than 4percent RSD for either the 3- or 4-O-methyl product isomers.The use of the product isomer preference ratios may be of clinical significance.
Organocatalytic enantioselective pictet-spengler reactions for the syntheses of 1-substituted 1,2,3,4-tetrahydroisoquinolines

A series of 1-substituted 1,2,3,4-tetrahydroisoquinolines was prepared from N-(o-nitrophenylsulfenyl)phenylethylamines through BINOL-phosphoric acid [(R)-TRIP]-catalyzed asymmetric Pictet-Spengler reactions. The sulfenamide moiety is crucial for the rate
Tetrahydroisoquinoline based sulfonamide hydroxamates as potent matrix metalloproteinase inhibitors

The synthesis and MMP inhibitory activity of a series of tetrahydroisoquinoline based sulfonamide hydroxamates are described. In nine MMPs tested, most of the compounds display potent inhibition activity except for MMP-7. Some subtle isozyme selectivity is observed by varying the substituents at the 6- and 7-positions and aromatic ring of arylsulfonyl groups.
