    Product Description

    QNZ 46 is an antagonist of NR2C- and NR2D-subunit containing NMDA receptors (IC50s = 6 and 3 µM, respectively, for receptors expressed in Xenopus oocytes).1 It is selective for NR2C- and NR2D-subunit containing NMDA receptors over receptors containing NR2A and NR2B subunits as well as over the AMPA receptor GluR1 (IC50s = 229, >300, and >300 µM, respectively). QNZ 46 acts in a noncompetitive and voltage-independent fashion that requires glutamate but not glycine binding for its activity.2

    WARNING This product is not for human or veterinary use.
