NVP-BSK805 trihydrochloride is a potent ATP-competitive inhibitor of JAK2, exhibiting IC50 values of 0.48 nM, 31.63 nM, 18.68 nM, and 10.76 nM against JAK2 JH1, JAK1 JH1, JAK3 JH1, and TYK2 JH1, respectively.
JAK2 inhibitor (IC50 = 397 nM). Also inhibits STAT3 and STAT5 phosphorylation. Inhibits cell growth and induces apoptosis in cells expressing the JAK2V617F mutation.

AC430 is a potent and specific small molecule inhibitor of janus kinase 2 (JAK2), which has been implicated as a target for therapy in both oncology and autoimmune disease. AC430 is currently being developed by Ambit. In preclinical studies, AC430 has exhibited potency against JAK2 and V617F mutated JAK2 in cell-based models that is at least equivalent to, and in most cases superior to, competing JAK2 inhibitors. In preclinical oncology and autoimmune models, AC430 is well tolerated and has significant efficacy at oral doses as low as 10 mg kg day.
