Fedratinib hydrochloride hydrate (TG-101348 hydrochloride hydrate) 是一种有效的，选择性的，ATP 竞争性和具有口服活性的 JAK2 抑制剂，对于 JAK2 和 JAK2V617F 激酶的 IC₅₀ 均为 3 nM。Fedratinib hydrochloride hydrate 对 JAK2 的选择性分别比 JAK1 和 JAK3 高 35 倍和 334 倍。Fedratinib hydrochloride hydrate 可诱导癌细胞凋亡 (apoptosis)，并可用于骨髓增生性疾病的研究。

Fedratinib hydrochloride hydrate (TG-101348 hydrochloride hydrate) is a potent, selective, ATP-competitive and orally active JAK2 inhibitor with IC 50 s of 3 nM for both JAK2 and JAK2V617F kinase. Fedratinib hydrochloride hydrate shows 35- and 334-fold selectivity over JAK1 and JAK3, respectively. Fedratinib hydrochloride hydrate induces cancer cell apoptosis and has the potential for myeloproliferative disorders research.

Fedratinib (TG101348) inhibits proliferation of a human erythroblast leukemia (HEL) cell line that harbors the JAK2V617F mutation, as well as a murine pro-B cell line expressing human JAK2V617F (Ba/F3 JAK2V617F), with an IC50 value of approximately 300 nM for either line. Proliferation of parental Ba/F3 cells was inhibited to a comparable level, with an IC50 value of ～420 nM.
Exposure of these cells to Fedratinib (TG101348) (0.1 μM, 0.3 μM, 1 μM, 3 μM, and 10 μM) reduces STAT5 phosphorylation at concentrations that parallel the concentrations required to inhibit cell proliferation.
Fedratinib (TG101348) (0.1 μM, 0.3 μM, 1 μM, 3 μM, and 10 μM) induces apoptosis in both HEL and Ba/F3 JAK2V617F cells in a dose-dependent manner. has not independently confirmed the accuracy of these methods. T
