ON044580 是一种 α-苯甲酰苯乙烯基苄基硫醚,是有效的,非 ATP 竞争性 JAK2 抑制剂,对 WT 和 V617F 突变型 JAK2IC50 分别为 1.23 μM、1.09 μM。ON044580 通过结合 JAK2 的 STAT-5 结合域或结合变构位点来抑制 JAK2 激酶活性。ON044580 在 JAK2V617F 阳性白血病细胞中发挥抗增殖作用,也可以有效诱导 Imatinib (HY-15463) 耐药慢性粒细胞白血病 (CML) 细胞凋亡。ON044580 还抑制 BCR-ABL 激酶的 WT 和 T315I 突变形式。ON044580 有用于以异常 JAK/STAT 信号为特征的骨髓增生性疾病的研究。

生物活性

ON044580, an α-benzoyl styryl benzyl sulfide, is a potent and non-ATP-competitive JAK2 kinase inhibitor with IC50s of 1.23 μM, 1.09 μM for WT and V617F mutant JAK2, respectively. ON044580 inhibits the JAK2 kinase activity either by binding to the STAT-5 binding domain of JAK2 or by binding to an allosteric site. ON044580 exerts its antiproliferative effect in JAK2V617F-positive leukemic cells. ON044580 effectively induces apoptosis of Imatinib (HY-15463)-resistant chronic myelogenous leukemia (CML) cells. ON044580 also inhibits both WT and T315I mutant forms of the BCR-ABL kinase. ON044580 has the potential for myeloproliferative disorders typified by aberrant JAK/STAT signaling[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
