6(1H)-triones as NQO1-directed antitumor agents were designed, synthesized, biologically evaluated. Compounds 3n, 3o and 3j proved to be good NQO1 substrates that showed increased metabolic rates relative to that of β-lapachone. In addition, 3n, 3o and 3j potently inhibited the growth of NQO1-rich breast cancer MCF-7 cell, liver hepatocellular HepG2 cell, and lung cancer A549 cell. In cellular mechanistic
设计、合成和生物学评估了一系列新型 4-取代-3,4-二氢苯并[ h ]喹啉-2,5,6(1 H )-三酮类化合物作为 NQO1 定向抗肿瘤剂。化合物3n、3o和3j被证明是良好的 NQO1 底物,与 β-拉帕酮相比,它们显示出更高的代谢率。此外,3n、3o和3j有效抑制富含 NQO1 的乳腺癌 MCF-7 细胞、肝肝细胞 HepG2 细胞和肺癌 A549 细胞的生长。在细胞机理研究中,代表化合物3o根据 NQO1 剂量触发 ROS 产生,并通过产生的氧化应激诱导 HepG2 细胞凋亡。在 HepG2 异种移植小鼠模型中,在 20 mg/kg 的剂量下,3o显着抑制了肿瘤的生长,而不影响动物的体重。
