A series of novel dehydroabietic acid derivatives containing both 1,2,3-triazole and oxazolidinone 4a–4t have been synthesized and their antiproliferative activity in vitro against HeLa, HepG2, MGC-803 and T-24 cell lines evaluated. Most of them displayed cell proliferation inhibition on four tested human malignant tumour cell lines to some degree. Among them, compound 4p exhibited promising cytotoxicity
合成了一系列含有 1,2,3-三唑和恶唑烷酮4a-4t的新型脱氢松香酸衍生物,并评估了它们对 HeLa、HepG2、MGC-803 和 T-24 细胞系的体外抗增殖活性。其中大多数对四种测试的人恶性肿瘤细胞系均表现出一定程度的细胞增殖抑制作用。其中,化合物4p表现出良好的细胞毒性,IC 50值范围为3.18至25.31 μM,对正常细胞的细胞毒性较弱。然后通过流式细胞术、Hoechst 33258染色、ROS生成测定和JC-1线粒体膜电位染色研究4p的作用机制,表明化合物4p诱导细胞凋亡,将有丝分裂过程阻滞在细胞周期的G1期,降低线粒体膜电位,增加细胞内ROS水平。综上所述,通过“1,2,3-三唑”连接体引入恶唑烷酮基团显着提高了脱氢松香酸的抗肿瘤活性,值得进一步研究。
