Research on thymidylate synthase inhibitors has been a hot spot for anticancer drug development. Here, based on the structures and pharmacological properties of two types of TS inhibitors, through a molecular assembly principle of drugs design, we designed and synthesized a series of 30 novel uracil derivatives as TS inhibitors. The antiproliferative ability of these compounds was evaluated against
胸苷酸合酶抑制剂的研究一直是抗癌药物开发的热点。在此,根据两种TS抑制剂的结构和药理特性,通过药物设计的分子组装原理,我们设计合成了30种新颖的尿嘧啶衍生物作为TS抑制剂。通过MTT分析评估了这些化合物对四种癌细胞系(A549,OVCAR-3,SGC-7901和HepG2)的抗增殖能力。它们中的大多数对所有测试的细胞系均表现出优异的活性。此外,hTS分析结果表明,这些化合物具有独特的体外抑制hTS活性的能力。值得注意的是,化合物13j对A549细胞表现出最强的活性(IC 50 = 1.18μM)和极显着的酶抑制(IC 50 = 0.13μM),优于培美曲塞(PTX,IC 50 = 3.29μM和IC 50 = 2.04μM)。流式细胞仪分析表明,化合物13j可以通过将细胞周期阻滞在G1 / S期来抑制A549细胞的增殖,进而诱导细胞凋亡。进一步的蛋白质印迹分析表明化合物13j可能下调周期检查点蛋白cyclin
