Fluoroethylnormemantine hydrochloride, a Memantine derivative, functions as an antagonist for the N-methyl-D-aspartate (NMDA) receptor. It can also serve as a positron emission tomography (PET) tracer, specifically as [18F]-Fluoroethylnormemantine hydrochloride. Notably, this compound displays a range of effects, including anti-amnesic, neuroprotective, antidepressant-like, and fear-attenuating properties.
