AG-490 | JAK-2 inhibitor

AG-490 (133550-30-8) is a potent inhibitor of the JAK-2 tyrosine kinase. In acute lymphoblastic leukemia (ALL) cells, which abundantly express JAK-2, AG-490 dose-dependently blocked cell growth, induced apoptosis and inhibited DNA synthesis. Blocks the growth of all pre-B ALL cells with no effect on normal B or T cells. Does not significantly inhibit other kinases such as Lck, Lyn, Btk, Syk and Src. Reduces liver injury in LPS-induced shock3. AG-490 is a useful tool for exploring the role of JAK2/STAT3 pathway in physiologic processes4.
