Used in pharmaceutical research as a potent and selective inhibitor of the enzyme TYK2 (tyrosine kinase 2), playing a key role in modulating immune responses. It is investigated for the treatment of autoimmune and inflammatory diseases such as psoriasis, lupus, and inflammatory bowel disease. The compound demonstrates high cellular activity and favorable pharmacokinetic properties, making it a valuable candidate in the development of targeted therapies with reduced systemic toxicity. Its structure enables specific binding to the TYK2 allosteric site, minimizing off-target effects on other kinases.
