Based on the novel allosteric site of deoxyhypusine synthase (DHPS), two series of 30 novel 5-(2-methoxyphenoxy)-2-phenylpyrimidin-4-amine derivatives as DHPS inhibitors were designed and synthesized. Among them, compound 8m, with the best DHPS inhibitory potency (IC50 = 0.014 μM), exhibited excellent inhibition against melanoma cells, which was superior to that of GC7. Besides, molecular docking and
基于脱氧马尿苷合酶(DHPS)的新型变构位点,设计并合成了两个系列的30种新型5-(2-甲氧基苯氧基)-2-苯基嘧啶-4-胺衍生物作为DHPS抑制剂。其中,化合物8m的DHPS抑制效力最好(IC 50 = 0.014 μM),对黑色素瘤细胞表现出优异的抑制作用,优于GC7。此外,分子对接和分子动力学(MD)模拟进一步证明化合物8m与DHPS的变构位点紧密结合。流式细胞术分析和酶联免疫吸附测定(ELISA)表明化合物8m可以抑制细胞内活性氧(ROS)水平。此外,通过蛋白质印迹分析,化合物8m有效激活caspase 3并降低GP-100、酪氨酸酶、eIF5A2、MMP2和MMP9的表达。此外,Transwell分析和伤口愈合分析均表明化合物8m可以抑制黑色素瘤细胞的侵袭和迁移。在体内研究中,肿瘤异种移植模型表明,化合物8m能有效抑制黑色素瘤的发展,且毒性低。
