PEAQX sodium

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 510289

CAS#: 2102348-87-6 (sodium)

Description: PEAQX, also known as NVP-AAM077; is a competitive antagonist at the NMDA receptor. Although originally described as 100-fold selective for GluN1/GluN2A receptors vs. GluN1/GluN2B receptors, more detailed studies of the Ki of PEAQX revealed it only shows a 5 fold difference in affinity for GluN1/GluN2A vs. GluN1/GluN2B receptors. It is also a potent anticonvulsant in animal tests.
