Used in pharmaceutical research as a potent and selective inhibitor of certain kinases involved in inflammatory and oncogenic signaling pathways. Shows promise in preclinical studies for treating autoimmune disorders and specific types of cancer due to its ability to modulate key cellular responses such as proliferation and cytokine production. Its sulfone and pyridine-containing structure enhances binding affinity and metabolic stability, making it suitable for oral dosing in experimental models. Also employed as a reference compound in assay development and target validation.
