Design, Synthesis, and Pharmacological Evaluation of Glutamate Carboxypeptidase II (GCPII) Inhibitors Based on Thioalkylbenzoic Acid Scaffolds
摘要:
A series of thiol-based glutamate carboxypeptidase II (GCPII) inhibitors have been synthesized with either a 3-(mercaptomethyl)benzoic acid or 2-(2-mercaptoethyl)benzoic acid scaffold. Potent inhibitors were identified from each of the two scaffolds with IC50 values in the single-digit nanomolar range, including 2-(3-carboxybenzyloxy)-5-(mercaptomethyl)benzoic acid 27c and 3-(2-mercaptoethyl)-biphenyl-2,3'-dicarboxylic acid 35c. Compound 35c was found to be metabolically stable and selective over a number of targets related to glutamate-mediated neurotransmission. Furthermore, compound 35c was found to be orally available in rats and exhibited efficacy in an animal model of neuropathic pain following oral administration.

inhibitors derived from the structures of the substrates involved in the methylationreaction. By covalently linking fragments of the NNMT substrates a diverse library of bisubstrate-like compounds was prepared. The ability of these compounds to inhibit NNMT was evaluated providing valuable insights into the structural tolerances of the enzyme active site. These studies led to the identification of new
