Herein, we propose that a dual inhibition of FLT3 and Mnk would provide a better clinical option for AML patients compared to targeting FLT3 alone. Thus, a series of N-phenyl-4-(thiazol-5-yl)pyrimidin-2-amines and 4-(indol-3-yl)-N-phenylpyrimidin-2-amines were prepared. Potent Mnk2 inhibitors, FLT3 inhibitors, and dual inhibitors of Mnk2 and FLT3 were identified and their anti-proliferative activities
迫切需要发现新型抗AML治疗药物,但该疾病复杂的异质性迄今阻碍了治疗方法的发展。FLT3抑制剂已在临床试验中显示出治疗潜力。但单药疗法已与由并行信号通路(包括MAPK和mTOR)激活介导的耐药性相关。因此,抑制两个信号通路的联系以及抑制FLT3可能是有利的。在本文中,我们建议与单独靶向FLT3相比,对FLT3和Mnk的双重抑制将为AML患者提供更好的临床选择。因此,一系列的N-苯基-4-(噻唑-5-基)嘧啶-2-胺和4-(吲哚-3-基)-N制备了-苯基嘧啶-2-胺。确定了有效的Mnk2抑制剂,FLT3抑制剂以及Mnk2和FLT3的双重抑制剂,并评估了它们对MV4-11 AML细胞系的抗增殖活性。与单独抑制FLT3或Mnk2相比,对FLT3和Mnk2的双重抑制导致MV4-11细胞凋亡的细胞死亡增加。
