tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20-30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies
FMS样酪氨酸受体激酶3(FLT3)的异常激活与20-30%的患者的急性髓细胞性白血病(AML)的发病机制有关。在这项研究中,我们确定了高选择性(苯基乙烯基)喹唑啉化合物家族作为FLT3-ITD和FLT3-D835Y激酶的新型有效抑制剂。通过生化和细胞增殖测定以及随后的小鼠异种移植研究,证实了它们的显着效果。我们的建模实验和化合物的化学结构预测了共价抑制的可能性。最有效的化合物触发了FLT3-ITD AML细胞的凋亡,但在不依赖FLT3的白血病和非白血病细胞系中作用微弱或没有作用。
