Used in pharmaceutical research as a potent inhibitor of Janus kinase 2 (JAK2), particularly in the development of targeted therapies for inflammatory diseases and certain cancers. Shows promising activity in suppressing cytokine signaling pathways involved in autoimmune disorders such as rheumatoid arthritis and psoriasis. Also investigated for its potential in treating myeloproliferative neoplasms driven by JAK2 mutations. High selectivity enhances its utility in minimizing off-target effects during therapeutic development.
