Human dihydroorotate dehydrogenase (hDHODH) is an attractive target for cancer therapy. Based on its crystal structure, we designed and synthesized a focused compound library containing the structural moiety of 1,4-benzoquinone, which possesses reactive oxygen species (ROS) induction capacity. Compound 3s with a naphtho[2,3-d][1,2,3]triazole-4,9-dione scaffold exhibited inhibitory activity against
人二氢乳清酸酯脱氢酶(h DHODH)是癌症治疗的诱人靶标。基于其晶体结构,我们设计并合成了包含1,4-苯醌结构部分的聚焦化合物文库,该化合物具有活性氧(ROS)诱导能力。具有萘[2,3- d ] [1,2,3]三唑-4,9-二酮骨架的化合物3s表现出对h DHODH的抑制活性。进一步优化导致化合物11k和11l抑制h DHODH活性,IC 50值分别为9和4.5 nM。蛋白质-配体共晶体结构清楚地描述了氢键和疏水相互作用11K和11升与ħ DHODH。化合物11k和11l显着抑制白血病细胞和实体瘤细胞增殖并诱导ROS产生,线粒体功能障碍,细胞凋亡和细胞周期停滞。化合物11l的纳米结晶在Raji异种移植模型中显示出显着的体内抗肿瘤作用。总的来说,该研究提供了具有h DHODH抑制和ROS诱导功效的新型双功能化合物11l,其代表了有希望的抗癌药物,值得进一步探索。
