MDL 105519 totally blocks the binding of [3H]glycine to rat meninges, with a Ki value of 10.9 nM. It is a powerful and selective ligand for the glycine recognition site. Comparing MDL 105519 to other receptor types under study, there is a roughly 10,000-fold increase in selectivity for the glycine recognition site. The NMDA-dependent reactions that are inhibited by MDL 105519 include alterations in cytosolic Ca2+ and Na+-Ca2+ currents in cultured neurons, increased [3H]TCP binding in meninges, and buildup of cyclic GMP in brain slices. It can be overcome by D-serine and the inhibition is non-competitive with NMDA [1].

| ln Vivo |
An antagonist of NMDA receptors in vivo is MDL 105519. By preventing the cameline-stimulated increase in cerebellar ring GMP content, MDL 105519 administered intravenously demonstrated NMDA receptor antagonistic activity in vivo. In epilepsy models that are genetically based, chemically generated, or electrically driven, this antagonistic relationship is linked to anticonvulsant activity. In a vocalization model created via rat separation, anxiolytic action was seen, but at lower levels, muscle relaxant activity was also noticeable. Increased dosages reduce rotarod performance but have no effect on prepulse suppression of the startle reflex or mesolimbic dopamine turnover [1].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.6583 mL | 13.2915 mL | 26.5830 mL | |
| 5 mM | 0.5317 mL | 2.6583 mL | 5.3166 mL | |
| 10 mM | 0.2658 mL | 1.3292 mL | 2.6583 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
