Used in research as a potent inhibitor of specific enzymes involved in neurodegenerative diseases, particularly targeting beta-secretase (BACE1) for potential Alzheimer’s therapy. Shows high blood-brain barrier permeability, making it valuable in developing central nervous system-active drugs. Also serves as a scaffold in medicinal chemistry for optimizing quinoline-based compounds with anti-inflammatory and neuroprotective properties. Investigated for its role in reducing amyloid-beta plaque formation in preclinical models.
