    D-AP5 purchased from MedChemExpress. Usage Cited in: CNS Neurosci Ther. 2022 Nov 15.  [Abstract]

    Treatment with the AMDAR inhibitor (NBQX) and NMDAR inhibitor (D-AP5) effectively reduce the expression of NMDAR (NR1, NR2A/2B) and AMPAR (GluA1, GluA2) in PFC, respectively.

    IC50 & Target


    In Vivo

    D-AP5 is a NMDA receptor antagonist. Chronic intraventricular infusion of D-AP5 causes a parallel dose-dependent impairment of spatial learning and long-term potentiation (LTP) in vivo. Intracerebral concentrations of D-AP5 fail to induce any measurable sensorimotor disturbance when spatial learning is prevented[2].
    D-AP5 infusion is associated with a progressive reduction in swim speed over trials. D-AP5 causes sensorimotor disturbances in the spatial task, but these gradually worsened as the animals fail to learn. Rats treated with D-AP5 show a delay-dependent deficit in spatial memory in the delayed matching-to-place protocol for the water maze[3].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
