Fluoroethylnormemantine, a derivative of Memantine, acts as an N-methyl-D-aspartate (NMDA) receptor antagonist. It can function as a positron emission tomography (PET) tracer, known as [18F]-fluoroethylnormemantine. This compound displays anti-amnesic, neuroprotective, antidepressant-like, and fear-attenuating properties.
