In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	2.5mg/ml (4.60mM)	Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Mechanism of Action

Targets/IC₅₀/Ki	GlyT1 (in cells stably expressing mGlyT1b) 22 nM GlyT1 (in cells stably expressing hGlyT1b) 25nM
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).
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.
