The cancer chemopreventive activity of quinoxaline derivatives 1–20 has been evaluated by studying the inhibitory effect on Epstein–Barr virus early antigen (EBV-EA) activation. The quinoxaline derivatives 1–20 showed inhibitory effect on EBV-EA activation without cytotoxicity on Raji cells. All compounds exhibited dose dependent inhibitory activities, most of them showed significant activity at 1000 mol
通过研究对爱泼斯坦-巴尔病毒早期抗原(EBV-EA)活化的抑制作用,评估了喹喔啉衍生物1 – 20的化学预防癌症活性。喹喔啉衍生物1 – 20对EBV-EA活化具有抑制作用,而对Raji细胞无细胞毒性。所有化合物均表现出剂量依赖性的抑制活性,其中大多数在1000摩尔比/ 12 - O-十四烷酰佛波醇-13-乙酸酯(TPA)时均表现出显着的活性。在最高测量浓度下,化合物7和9对代表性的对照品齐墩果酸对EBV-EA的活化表现出更强的抑制作用。此外,化合物7 - 10结果显示在肝癌HepG2人酪氨酸激酶(TRK)和类似于阳性对照乳腺癌MCF-7细胞系,多柔比星的有效的和选择性的抑制作用。
