描述 | Bitopertin is a potent and noncompetitive glycine reuptake inhibitor targeting on GlyT1 (glycine transporter type 1), with IC50 value of 25nM. Bitopertin enhanced NMDA-dependent long-term potentiation at 100 nM but not at 300 nM in hippocampal CA1 pyramidal cells. It dose-dependently increased cerebrospinal fluid and striatal levels of glycine measured by microdialysis in rats. Also, it attenuated hyperlocomotion induced by the psychostimulant D-amphetamine or the NMDA receptor glycine site antagonist L-687,414 in mice. Additionally, it prevented the hyper-response to D-amphetamine challenge in rats treated chronically with phencyclidine, an NMDA receptor open-channel blocker. Bitopertin is usually used in study of schizophrenia. It can modulate both glutamatergic and dopaminergic neurotransmission in animal experiments that model aspects of schizophrenia. | ||
作用机制 | Bitopertin could competitively block [3H]ORG24598 binding sites at human GlyT1b.[1] |
