tyrosine kinase 3 (FLT3) is one of the most pursued targets in the treatment of acute myeloid leukaemia (AML) as its gene amplification and mutations, particularly internal tandem duplication (ITD), contribute to the pathogenesis of AML and the resistance to known FLT3 inhibitors. To conquer this challenge, there is a quest for structurally novel FLT3 inhibitors. Herein, we report the discovery of a new series
猫McDonough肉瘤(FMS)样酪氨酸激酶3(FLT3)是急性髓细胞白血病(AML)的治疗中最受关注的靶标之一,因为其基因扩增和突变,尤其是内部串联重复(ITD)有助于发病AML和对已知FLT3抑制剂的耐药性。为了克服这一挑战,寻求结构新颖的FLT3抑制剂。在这里,我们报告发现了一系列新的4-氮杂芳基-N-苯基嘧啶-2-胺衍生物作为有效的和选择性的FLT3抑制剂。化合物12b和12r能够抑制各种突变的FLT3激酶,包括ITD和D835Y突变体;后者同工型与获得性耐药密切相关。此外,这两种化合物显示抗增殖特异性FLT3 -ITD-窝藏细胞系(我。Ë在那些与野生型激酶或即使没有FLT3表达的表达。,MV4-11和MOLM-13细胞)。在使用MV4-11细胞的机制研究中,发现12b可以减少FLT3关键下游效应子的磷酸化并诱导凋亡,从而支持FLT3-ITD靶向的抗增殖作用机制。
