A novel series of substituted pyrido[3,2-d]-1,2,3-triazines were designed and synthesized as Pim-1 inhibitors through scaffold hopping. Most of the derivatives showed potent in vitro Pim-1 inhibitory activities and anti-proliferative effects toward prostate cancer cells. Among them, 6b, 6h and 6m showed the best Pim-1 inhibitory activity with IC50 values of 0.69, 0.60 and 0.80 μM, respectively. Furthermore
设计了一系列新颖的取代吡啶并[3,2-d] -1,2,3-三嗪,并通过支架跳跃合成为Pim-1抑制剂。大多数衍生物对前列腺癌细胞显示出有效的体外Pim-1抑制活性和抗增殖作用。其中6b,6h和6m表现出最佳的Pim-1抑制活性,IC50值分别为0.69、0.60和0.80μM。此外,化合物6b,6i,6j和6m对人前列腺癌LNcap和PC-3细胞系显示出很强的抑制活性,其IC50值处于低微摩尔水平。结构活性关系分析表明,在C-6位适当的取代有助于激酶抑制和抗增殖作用。而且,免疫印迹分析表明6j可以剂量依赖性地降低PC-3细胞中p-BAD和p-4E-BP1的水平。对接研究表明,支架的3-N与Lys67形成氢键,芳族4-苯胺与Phe49形成关键的π-π堆积。综上所述,该研究可能为开发作为新型Pim-1抑制剂的吡啶并[3,2-d] -1,2,3-三嗪支架提供了第一见。
