Elevation of glycine levels by inhibition of the glycine transporter-1 (GlyT-1) and activation of the NMDA receptor is a potential strategy for the treatment of schizophrenia. A novel series of 2-arylsulfanylphenyl-1-oxyalkyl amino acids have been identified. The most prominent member of this series S-1-2-[3-(3-fluoro-phenylsulfanyl)biphenyl-4-yloxy]ethyl} pyrrolidine-2-carboxylic acid (38) is a potent GlyT-1 inhibitor (IC50 = 59 nM). In vitro and in vivo assessment of CNS exposure indicates this compound is a likely substrate for active efflux transporters. (c) 2006 Elsevier Ltd. All rights reserved.
