4P58 - PubMed Abstract: 
Catechol O-methyl transferase belongs to the diverse family of S-adenosyl-l-methionine transferases. It is a target involved in the treatment of Parkinson's disease. Here we present a fragment-based screening approach to discover noncatechol derived COMT inhibitors which bind at the SAM binding pocket. We describe the identification and characterization of a series of highly ligand efficient SAM competitive bisaryl fragments (LE = 0.33-0.58). We also present the first SAM-competitive small-molecule COMT co-complex crystal structure.
