Used as a potent inhibitor in pharmaceutical research, particularly targeting Janus kinase (JAK) enzymes. It shows promise in the development of treatments for autoimmune diseases such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease due to its ability to modulate immune signaling pathways. Its structure allows for high selectivity and improved pharmacokinetic properties, making it a valuable scaffold in optimizing JAK inhibitor candidates. Also investigated for potential use in oncology due to the role of JAK-STAT signaling in certain cancers.
