A negative allosteric modulator selective for NR2A containingnMDA receptors (pIC50 = 6.8 and <4.3uM for NR2A and NR2B, respectively). No effect on NR2B-containingnMDA receptors with concentrations less than 50 mM. Inhibition on NR2A containingnMDA receptors is glycine (or D-serine)-binding, but not glutamate-binding, dependent.Formula:C21H17ClFN3O4SSolubility:DMSOPrimary Target:NMDA receptorsMolar Mass:461.89Storage and Stability:May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
