The synthesis and SAR of 2-arylsulfanyl-phenyl piperazinyl acetic acids as glyT-1 inhibitors
摘要:
Elevation of glycine levels and activation of the NMDA receptor by inhibition of the glycine transporter 1 (GlyT-1) is a potential strategy for the treatment of schizophrenia. A novel series of GlyT-1 inhibitors have been identified containing,the 2-arylsulfanyl-phenylpiperazine motif. The most prominent member of this series, (R)-4-[5-chloro-2-(4-methoxy-phenylsulfanyl)- phenyl]-2-methyl-piperazin-1-yl-acetic acid (31) is a potent glycine transporter-1 inhibitor (IC50 = 150 nM), which elevated glycine levels in rat ventral hippocampus as measured by microdialysis in vivo at doses of 1.2-4.6 mg/kg s.c.
