inhibitory activities but poor selectivities against the both MLL-rearranged MV4-11 cells and the non MLL-rearranged Kasumi-1 cells than those of 3a and 3e, which suggested that the introduction of the amino side chain would be beneficial for their anti leukemia cells proliferation activities, possibly due to the improvement of the fat solubility. Additionally, the direct cellular inhibition activities were
通过在DOT1L铅抑制剂3a上进行结构修饰,设计并合成了一系列含有氨基侧链的新型嘧啶基氨基喹啉衍生物8(ai)和9(ai),以及双氨基喹啉类似物3(be)。已经评估了所有化合物的DOT1L抑制活性。结果表明,大多数化合物具有很强的抗DOT1L活性。化合物3e,8h和9e是IC 50每种类别中最有潜力的化合物值分别为1.06±0.35μM,5.72±1.56μM和3.55±1.28μM。此类抑制剂通过基于表面等离振子共振(SPR)的结合测定表达了与DOT1L的显着结合相互作用。分子对接实验的结果表明它们可以占据DOT1L的SAM结合口袋。与3a和3e的化合物相比,化合物8h和9e对MLL重排的MV4-11细胞和非MLL重排的Kasumi-1细胞均表现出更好的抑制活性,但选择性较差。,这表明引入氨基侧链可能有助于其抗白血病细胞的增殖活性,这可能是由于脂肪溶解度的提高所致。此外,在qRT-PCR
