mutations of FMS-like tyrosine kinase 3 (FLT3) are present in approximately one third of acute myeloid leukemia (AML) patients, which has been proposed as a promising drug target for AML therapy. A series of indolin-2-one derivatives bearing different groups at the solvent interface position based on sunitinib as FLT3 inhibitors were designed, synthesized and evaluated in FLT3-dependent human AML cell line
FMS样酪氨酸激酶3(FLT3)的激活突变存在于大约三分之一的急性髓细胞性白血病(AML)患者中,这已被提出作为AML治疗的有希望的药物靶标。在舒尼替尼作为FLT3抑制剂的基础上,设计,合成和评估了一系列在溶剂界面位置带有不同基团的吲哚啉-2-酮衍生物,并在依赖于FLT3的人类AML细胞MV4-11中进行了评估。结构-活性关系(SAR)分析表明,溶剂界面位置的杂环烷烃可显着提高抑制MV4-11细胞系增殖的能力。化合物10a和10d表现出更好的功效(MV4-11,IC 50:10a为14.7 nM ,IC 50为24.8 nM。与阳性对照舒尼替尼(MV4-11,IC 50:38.5 nM)相比10d)。激酶和细胞抑制试验显示10d(FLT3,IC 50:5.3 nM)是有效的选择性FLT3抑制剂。此外,药代动力学实验表明,10d小鼠具有良好的口服生物利用度,C max,T max,T 1/2
