Scientific background

MPX-004 is a synthetic compound that acts as a potent and selective GluN2A-containing NMDA receptor antagonist with an IC50 value of 79 nM in HEK cells1.MPX-004 is a pyrazine-containing antagonist with optimal halogen substituents on the phenylsulfonamide aryl ring. It is used as a pharmacological tool for studying the physiology of NMDA receptors containing the GluN2A subunit1.NMDA receptors are heterotetramers composed by 2 GluN1 obligatory subunits and 2 GluN2 (A-D) or GluN3 (A-B) regulatory subunits. GluN2A is the most abundant subunit in the mammalian CNS. Physiological and genetic evidence show that GluN2A-containing receptors are involved in autism, schizophrenia, childhood epilepsy and neurodevelopmental disorders such as Rett Syndrome1,2.
