Sodium phenylbutyrate is a small molecule with multiple mechanisms of action, including histone deacetylase inhibition, glutamine scavenging, and modulation of protein folding. In neuroscience, it has been shown to reduce tau pathology in Alzheimer's disease models, inhibit glioma cell proliferation, and enhance neuroprotective gene expression. Its ability to cross the blood-brain barrier and modulate epigenetic and metabolic pathways makes it a promising candidate for treating neurodegenerative and neurodevelopmental disorders.
