of 2-benzoylquinazolin-4(3H)-one skeleton was achieved successfully via the I2/DMSO catalytic system. A series of penipanoid C-inspired 2-(3,4,5-trimethoxybenzoyl)quinazolin-4(3H)-one derivatives was synthesized and evaluated for their cytotoxic activities against four cancer cell lines, HepG2, Bel-7402, A549, and U251. Among these compounds, 4a was the most effective one with IC50 values of 1.22 μM
肝细胞癌 (HCC) 是最常见的肝癌形式,也是全球癌症相关死亡的第四大原因。索拉非尼等一线药物对 HCC 患者仅提供适度的益处。在本研究中,通过I 2 /DMSO 催化体系成功实现了2-苯甲酰基喹唑啉-4(3 H )-one 骨架的克级合成。合成了一系列受 penipanoid C 启发的 2-(3,4,5-三甲氧基苯甲酰基)喹唑啉-4(3 H )-one 衍生物,并评估了它们对四种癌细胞系 HepG2、Bel-7402、A549、和U251。在这些化合物中,4a是最有效的一种,IC 50值为 1.22 μ M 和 1.71 μM 分别针对 HepG2 和 Bel-7402 细胞。机制研究表明,4a通过阻止细胞周期抑制肝细胞癌细胞增殖。此外,4a通过诱导活性氧的产生和提高凋亡相关蛋白的表达来诱导 HepG2 细胞凋亡。更重要的是,4a在 HepG2 异种移植模型中显示出显着的体内抗癌作
