Although it does not depend on the binding of cytokines and their cognate receptor, mutation of JAK2 can auto-phosphorylate and activate the downstream factors abnormally, resulting in uncontrollable cell proliferation and suppression of apoptosis [11–14]. Thus, inhibiting JAK2 is an effective treatment for cancer and related diseases. Ruxolitinib is the most studied JAK2 inhibitors in psoriasis since its approval by FDA in 2011 [15,16]. In the meantime, more small-molecule inhibitors of JAK2 have entered clinical trials. For example, Gandotinib (LY-2784 544) is used for the treatment of myeloproliferative neoplasms, and Lestaurtinib (CEP-701) is used in patients for acute myeloid leukemia (AML). More inhibitors of JAK2 are currently being discovered and studied [17–19].
