Abstract: Janus Kinase (JAK), a nonreceptor protein tyrosine kinase, has emerged as an
excellent target through research and development since its discovery in the 1990s. As
novel small-molecule targeted drugs, JAK inhibitor drugs have been successfully used in
the treatment of rheumatoid arthritis (RA), myelofibrosis (MF), and ulcerative colitis
(UC). With the gradual development of JAK targets in the market, JAK inhibitors have
also received considerable feedback in the treatment of autoimmune diseases, such as
atopic dermatitis (AD), Crohn's disease (CD), and graft-versus-host disease (GVHD).
This article reviews the research progress of JAK inhibitor drugs, focusing on the existing
JAK inhibitors in the market and some JAK inhibitors in clinical trials currently. In addition,
the synthesis of various types of JAK inhibitors and the effects of different drug
structures on drug inhibition and selectivity are summarized.
