discovery of 1-(5-(tert-butyl)isoxazol-3-yl)-3- (3-fluorophenyl)urea derivatives as new FLT3 inhibitors that are able to overcome the drug resistance mutations: the secondary D835Y and F691L mutations on the basis of the internal tandem duplications (ITD) mutation of FLT3 (FLT3-ITD/D835Y and FLT3-ITD/F691L, respectively). The most potent compound corresponds to 1-(5-(tert-butyl)isoxazol-3-yl)-3-(4-((6,7
在这里,我们报告发现1-(5-(叔丁基)异恶唑-3-基)-3-(3-氟苯基)脲衍生物作为能够克服药物抗性突变的新型FLT3抑制剂的发现:次级D835Y和F691L突变基于FLT3的内部串联重复(ITD)突变(分别为FLT3-ITD / D835Y和FLT3-ITD / F691L)。最有效的化合物对应于1-(5-(叔丁基)异恶唑-3-基)-3-(4-((6,7-二甲氧基喹啉-4-基)氧基)-3-氟苯基)脲(4d),分别显示针对FLT3-ITD,FLT3-ITD / F691L和FLT3-ITD / D835Y的IC 50 s(半数最大抑制浓度)分别为0.072 nM,5.86 nM和3.48 nM。化合物4d在激酶谱分析中也显示出对FLT3的良好选择性。集体,4d 可能是很好的铅化合物,值得进一步深入研究。
