🧪 Overview
Selective GluN2A activation or GluN2B inhibition shifts balance from excitotoxic extrasynaptic signaling toward neuroprotective synaptic signaling. Deprioritized due to memantine's modest clinical efficacy and technical challenges in confirming in vivo compartmentalization.

⚖️ Evidence Matrix3 supports3 contradicts
Contradicts
Memantine (current AD therapeutic) shows only modest clinical benefit
Contradicts
Ifenprodil also binds sigma-1 receptors - neuroprotection may be sigma-1 mediated
Contradicts
In vivo synaptic/extrasynaptic compartmentalization technically difficult to confirm
