Generic protein structure example

Sodium- and chloride-dependent glycine transporter 1 is a protein that in humans is encoded by the SLC6A9 gene.[1][2][3]

Selective inhibitors

Elevation of extracellular synaptic glycine concentration by blockade of GlyT1 has been hypothesized to potentiate NMDA receptor function in vivo and to represent a rational approach for the treatment of schizophrenia and cognitive disorders. Several drug candidates have reached clinical trials.[4]

  • ASP2535[5]
  • Bitopertin (RG1678), which has entered phase II trials for the treatment of schizophrenia[6]
  • Org 25935
  • PF-03463275 (in phase II trial)
