INCB 018424 phosphate是一种有效的JAK1/2抑制剂，其IC50s分别为3.3 nM/2.8 nM，显示出超过JAK 3 130倍的选择性。

INCB018424有效并选择性地抑制JAK2V617F介导的信号传导和增殖。Ruxolitinib以186 nM的EC50抑制HEL细胞的生长。Ruxolitinib显著增加Ba/F3-EpoR-JAK2V617F细胞系统中的凋亡，并抑制原发性MPN患者样本中的造血祖细胞增殖[1]。

Ruxolitinib phosphate(180 mg/kg，口服)减少接种JAK2V617F表达细胞的小鼠的肿瘤负荷，而不引起贫血或淋巴细胞减少[1]。
