生物活性:
Fedratinib hydrochloride hydrate (TG-101348 hydrochloride hydrate) is a potent, selective, ATP-competitive and orally active JAK2 inhibitor with IC50s 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.

体内研究:
Fedratinib hydrochloride hydrate (TG101348;60-120 mg/kg;口服强饲法;每天两次;42 天;C57Bl/6 小鼠) 处理显示处理动物的红细胞增多症呈剂量依赖性减少,脾肿大明显减少。Animal Model:C57Bl/6 mice induced by the JAK2V617F mutation
Dosage:60 mg/kg, 120 mg/kg
Administration:Oral gavage; twice daily; for 42 days
Result:Showed a statistically significant reduction in hematocrit and leukocyte count, a dose-dependent reduction/elimination of extramedullary hematopoiesis.

体外研究:
Fedratinib hydrochloride hydrate (TG101348) 抑制携带 JAK2V617F 突变的人成红细胞白血病 (HEL) 细胞系以及表达人 JAK2V617F 的小鼠前 B 细胞系 (Ba/F3 JAK2V617F) 的增殖,IC50 每条线的值约为 300 nM。亲代 Ba/F3 细胞的增殖被抑制到相当水平,IC50 值为 ~420 nM。将这些细胞暴露于 Fedratinib hydrochloride hydrate (TG101348) (0.1 μM、0.3 μM、1 μM、3 μM 和 10 μM) 降低 STAT5 磷酸化的浓度与抑制细胞增殖所需的浓度相当。 Fedratinib hydrochloride hydrate (TG101348) (0.1 μM、0.3 μM、1 μM、3 μM 和 10 μM) 以剂量依赖性方式诱导 HEL 和 Ba/F3 JAK2V617F 细胞凋亡。
