Used in research related to neurodegenerative diseases due to its structural similarity to compounds involved in Parkinson’s and Alzheimer’s pathologies. Acts as a precursor in the synthesis of β-carboline alkaloids, which exhibit a range of biological activities including antimicrobial, antiviral, and anticancer properties. Also investigated for its potential role as a monoamine oxidase inhibitor, influencing neurotransmitter levels in the brain. Found naturally in some plants and foods, it contributes to studies on diet-derived compounds affecting central nervous system function.
