Onfasprodil
Onfasprodil (MIJ-821) is a selective intravenous NMDA receptor NR2B subunit negative allosteric modulator (NAM). Onfasprodil inhibits the activity of NR2B-NMDA receptors. Onfasprodil has a rapid antidepressant effect. Onfasprodil can be used for the research of treatment-resistant depression (TRD).

N-Methyl-d-aspartate (NMDA) receptors are widely expressed in the mammalian central nervous system (CNS). Activation of the NMDA receptors depends on the simultaneous binding of two co-agonists: glutamate and either glycine or d-serine. Glutamate binds to the GluN2 subunits, and binding of glycine to the GluN1 subunit results in activation via the opening of the channel pore and subsequently causes the flow of ions through NMDA receptors. Functionally, NMDA receptors mediate excitatory synaptic transmission and plasticity by allowing the flux of calcium ions into neurons. NMDA-dependent synaptic plasticity is essential for many types of learning and memory formation. Dysfunction of NMDA receptors has been implicated in many neurological and psychiatric disorders, including Alzheimer’s disease, Parkinson’s disease, neuropathic pain, stroke, brain trauma, schizophrenia, and depression.
