The U.S. FDA has approved Sun Pharmaceutical Industries Ltd.’s Leqselvi (deuruxolitinib), a JAK1 and JAK2 inhibitor for adults with severe alopecia areata, a chronic autoimmune disease. The twice-daily, oral treatment will be targeting a company-estimated market of about 300,000 people in the U.S. This is the third FDA-approved treatment for severe alopecia areata in the past three years.

Ajax Therapeutics Inc. has received clearance for its IND application from the FDA to initiate a phase I study of AJ1‑11095, a first-in-class type II JAK2 inhibitor, for the treatment of patients with myelofibrosis.
Work at Hangzhou Highlightll Pharmaceutical Co. Ltd. has led to the development of tyrosine-protein kinase JAK1, JAK2 and non-receptor tyrosine-protein kinase TYK2 inhibitors.
Ajax Therapeutics Inc. has synthesized heterocyclic amide and urea compounds acting as tyrosine-protein kinase JAK2 inhibitors and thus reported to be useful for the treatment of cancer and myelofibrosis.
Cgenetech (Suzhou, China) Co. Ltd. has synthesized tyrosine-protein kinase JAK2 inhibitors reported to be useful for the treatment of autoimmune diseases, myeloproliferative diseases and graft-versus-host disease.
Synthesis and optimization of substituted 2-amino[1,2,4]-triazolopyrimidines and related heterocycles by Wuyi University investigators has led to the identification of compound [I], and its water-soluble phosphate sodium salt prodrug, compound [II].
Type I JAK2 inhibitors improve symptoms and outcomes of patients with myeloproliferative neoplasms (MPNs), but mutant allele JAK2 VF remains unchanged with this therapy. Type II JAK2 inhibitors bind the inactive conformation of the kinase domain and reduce the fraction of JAK2 VF mutant allele in vivo, suggesting an improved approach for JAK2 inhibition. Ajax Pharmaceuticals Inc. presented preclinical data on the type II JAK2 inhibitor AJ1-10502 for the treatment of MPNs.
