  6-Substituted 1,4-Naphthoquinone Oxime Derivatives (III): Synthesis and Cytotoxic Evaluation

  摘要：

  As a continuous study, a set of 23 new 6-substituted 1,4-naphthoquinone oxime derivatives are synthesized and screened for their in vitro cytotoxic activity. Four of those oxime derivatives demonstrate more potent cytotoxic activity towards K562, HCT-15, and HCT-116 cell lines than a reference drug 5-Fu. In particular, compound 21g exhibits the strongest inhibitory activity against K562 cell lines with IC50 values of 1.25 mu M. According to flow cytometry data, compound 21g can arrest cell cycle at S phase and induce a strong apoptotic response in K562 cells. The preliminary structure-activity relationship study shows that the nature of substituents in positions 6 and 1' of 1,4-naphthoquinone derivatives significantly affect their cytotoxic activity.

  Some 2- or 6-acyl-5,8-dimethoxy-1,4-naphthoquinone (DMNQ) derivatives were synthesized and evaluated for inhibition of DNA topoisomerase I and cytotoxicity against L1210 cells. Compared with 2-acyl-DMNQ derivatives, 6-acyl-DMNQ compounds, bearing a higher electrophilic quinone moiety, showed a higher potency in the inhibition of DNA topoisomerase I and the cytotoxicity, implying the possible participation

  合成了一些2-或6-酰基-5,8-二甲氧基-1,4-萘醌（DMNQ）衍生物，并评估了其对DNA拓扑异构酶I的抑制作用以及对L1210细胞的细胞毒性。与2-酰基-DMNQ衍生物相比，带有较高亲电醌部分的6-酰基-DMNQ化合物在抑制DNA拓扑异构酶I和细胞毒性方面显示出更高的效力，这暗示着亲电子芳基化可能参与了其生物活性。酶抑制的时间和温度依赖性表明芳基化不可逆地发生。在6-酰基-DMNQ衍生物中，具有中等大小（C（5）-C（9））的酰基的衍生物在生物活性方面比其他衍生物更高。此外，为了有效抑制DNA拓扑异构酶I，

  Oxidative demethylation of 2-(α-hydroxyalkyl- and α-oxoalkyl)-1,4,5,8-tetramethoxynaphthalene with (NH4)2Ce(NO3)6 gave two isomeric dimethoxynaphthoquinones: 2-substituted and 6-substituted 5,8-dimethoxy-1,4-naphthoquinones. Further demethylations of the former isomers to the corresponding dihydroxynaphthoquinones required an AgO–40%HNO3 reagent, while the latter isomers needed AlCl3 as the demethylation

  resistance (MDR) to anticancer drugs is the primary impediment to successful treatment of cancer. Hunting for new compounds with potent anti-MDR activity is an effectual approach to conquer cancer drug resistance. In this work, 33 new sulfur-containing 1,4-naphthoquinone oxime derivatives were prepared and investigated for their cytotoxicity against a panel of tumor cell lines and fibroblast normal

  对抗癌药物的多药耐药性（MDR）是成功治疗癌症的主要障碍。寻找具有有效抗MDR活性的新化合物是征服癌症耐药性的有效方法。在这项工作中，制备了33种新的含硫的1,4-萘醌肟衍生物，并研究了它们对一组肿瘤细胞系和成纤维细胞正常细胞系的细胞毒性。基于细胞的分析表明，大多数靶标化合物均比阳性对照具有更强的细胞毒性。同时，所有化合物均对正常细胞无毒。更重要的是，发现这些肟衍生物对耐药癌细胞系的细胞毒活性要强于对药物敏感细胞系的细胞毒活性（抗药性系数（ADRC）> 1）。这些，化合物12 m被认为是最有效的分子，对MDR子系的IC50值在0.29±0.01至1.33±0.05μM的范围内。进一步的机制研究表明12 m可以抑制菌落形成，引起G1期阻滞并促进通过增加Bel7402 / 5-FU细胞的Bax / Bcl-2比值介导的细胞凋亡。我们的发现为开发含硫的1,4-萘醌肟衍生物作为潜在的抗MDR药物提供了有希望的起点。
