Bitopertin R enantiomer (RG1678 R enantiomer) is the R-enantiomer of Bitopertin. Bitopertin is a noncompetitive glycine reuptake inhibitor and inhibits glycine uptake at human GlyT1 (IC50: 25 nM).
ASP2535 is a potent, selective, orally bioavailable, brain permeable and centrally-active glycine transporter-1 (GlyT1) inhibitor.ASP2535 can improve cognitive impairment in animal models of schizophrenia and Alzheimer's disease[1].
