Used as a potent and selective inhibitor in biochemical research, particularly targeting enzymes involved in inflammatory and neurodegenerative pathways. Its selenium-containing structure enhances binding affinity and metabolic stability, making it suitable for studying enzyme modulation in cellular models. Commonly applied in the development of pharmacological probes for central nervous system disorders due to its ability to cross the blood-brain barrier. Also utilized in structure-activity relationship (SAR) studies to optimize sulfonamide-based therapeutics.
