FMS-like tyrosine kinase 3 (FLT3) was an important therapeutic target in acute myeloid leukemia (AML). We synthesized two series of 4-((6,7-dimethoxyquinoline-4-yl)oxy)aniline derivatives possessing the semicarbazide moiety and 2,2,2-trifluoro-N,N′-dimethylacetamide moiety as the linker. The cell proliferation assay in vitro against HL-60 and MV4-11 cell lines demonstrated that most series I compounds
FMS样酪氨酸激酶3(FLT3)是急性髓细胞性白血病(AML)的重要治疗靶标。我们合成了两个系列的4-((6,7-二甲氧基喹啉-4-基)氧基)苯胺衍生物,它们具有氨基脲部分和2,2,2-三氟-N,N'-二甲基乙酰胺部分作为连接基。针对HL-60和MV4-11细胞系的体外细胞增殖试验表明,大多数含有氨基脲部分的系列I化合物的效力均高于卡波替尼。此外,酶分析表明,化合物12c和12g是有效的FLT3抑制剂,IC 50值分别为312 nM和384 nM。之后,还进行了分子对接分析,以确定FLT3与目标化合物之间可能的结合方式。
