Used in pharmaceutical research as a structural analog and intermediate for developing bioactive compounds targeting the central nervous system and immune modulation. The piperidine-2,6-dione core exhibits potential in modulating dopamine and serotonin receptors, anti-inflammatory activity, and immune response regulation. Investigated for synthesizing derivatives with antidepressant, antipsychotic, anti-cancer, and immunomodulatory effects. Commonly employed in the preparation of piperidine-based drug candidates for neurological disorders, oncology, and autoimmune conditions. Not used directly in clinical settings but essential in early-stage drug discovery.
