Baricitinib (CAT: I000674) is a selective inhibitor of Janus kinase (JAK) enzymes, specifically targeting JAK1 and JAK2. It is primarily used in the treatment of inflammatory conditions, such as rheumatoid arthritis. Baricitinib works by blocking the activity of JAK enzymes, which play a crucial role in the signaling pathways involved in inflammation and immune response. By inhibiting JAK1 and JAK2, baricitinib helps to reduce inflammation and alleviate the symptoms associated with rheumatoid arthritis.
