Biological Activity

Description Bitopertin (RG1678,RO-4917838) is a potent inhibitor of glycine transporter 1 (GlyT1), with Ki of 8.1 nM for human hGlyT1b and IC50 of 22-25 nM in Chinese hamster ovary cells.
Targets
GlyT1 [1]
(in cells stably expressing mGlyT1b)
GlyT1 [1]
(in cells stably expressing hGlyT1b)
22 nM 25nM
In vitro
In vitro RG1678 noncompetitively inhibits [3H]glycine uptake in cells stably expressing hGlyT1b and mGlyT1b, with IC50 values of 25 ± 2 nM and 22 ± 5 nM, respectively (n = 6) and competitively displaces [3H]ORG24598 binding with a Ki of 8.1 nM at human hGlyT1b in membranes from Chinese hamster ovary cells. RG1678 has no effect on hGlyT2-mediated [3H]glycine uptake up to 30 μM concentration. There is no significant species difference in the pharmacology for RG1678 based on the ability of the compound to displace [3H]ORG24598. In hippocampal CA1 pyramidal cells, RG1678 enhances NMDA-dependent long-term potentiation (LTP) at 30 nM (213 ± 18%; n=7), 100 nM (269 ± 44%, n=13) but not at 300 nM (152 ± 14%; n = 9)[1].
In Vivo
In vivo Administration of RG1678 produces a long-lasting (>3h) dose-dependent increase in extracellular glycine levels both in microdialysis experiments conducted in rats and CSF of rats. In mice, RG1678 dose-dependently and significantly attenuates hyperlocomotion induced by the psychostimulant D-amphetamine. RG1678 also prevents the hyper-response to D-amphetamine challenge in rats treated chronically with phencyclidine, an NMDA receptor open-channel blocker[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
