5-dicarboxamides (I45DCs) were prepared and tested in order to determine their antiproliferative activity against HL-60 cells. The design of the I45DCs was based in part on the structures of trisubstituted purines complexed with cyclin dependent kinase 2 (cdk2), a protein important in regulating the G1/S transition in the cell cycle, and the intramolecular hydrogen bond in I45DCs that predisposes the conformation
制备并测试了一系列N,N'-二取代的咪唑-4,5-二甲酰胺(I45DCs),以确定它们对HL-60细胞的抗增殖活性。I45DC的设计部分基于与细胞周期蛋白依赖性激酶2(cdk2)复合的三取代嘌呤的结构,一种在细胞周期中调节G1 / S过渡的重要蛋白质以及I45DCs中的分子内氢键模仿取代的腺苷的构象。通过MTS线粒体功能测定法测定的IC50在2.5-25 microM范围内,本研究中的大多数I45DC抑制HL-60细胞的增殖。I45DC的SAR与cdk2的ATP结合位点中预期的氢键相互作用一致。因此,
