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.
