Used in pharmaceutical research as a key scaffold for developing central nervous system (CNS) agents. Shows potential in the design of ligands targeting serotonin and dopamine receptors, particularly for treating neurological disorders such as depression, schizophrenia, and Parkinson’s disease. Its structure allows for good blood-brain barrier penetration, making it suitable for neuroactive drug development. Also employed in the synthesis of novel kinase inhibitors for oncology applications. Commonly modified to improve selectivity, metabolic stability, and bioavailability in drug candidates.
