  Synthesis and evaluation of novel alkannin and shikonin oxime derivatives as potent antitumor agents

  摘要：

  A set of forty alkannin and shikonin oxime derivatives were firstly designed and synthesized. Their cytotoxicities against three kinds of tumor cells and a normal cell line were tested and compared with alkannin and shikonin. The cell-based investigation demonstrated that some oxime derivatives were more or comparatively effective to the lead compounds, especially their selective and excellent antitumor activities towards K562 cells with no toxicity in normal cells. We may conclude that oximate modification to the mother nucleus of alkannin and shikonin is an available approach to acquire potent antitumor agents.

  5、8 - O-二甲基酰基紫草素衍生物的6-异构体的半合成和抗肿瘤活性

  摘要：

  我们最近发现5、8- O-二甲基酰基紫草素衍生物显示出对MCF-7的选择性，并且对正常细胞没有毒性。在此，从紫草素开始合成一系列相应的5、8 - O-二甲基酰基紫草素衍生物的6-异构体。细胞毒性的体外证据表明，大多数化合物比紫草素更具活性或与之相比，并保留了对MCF-7，MDA-MB-231的选择性，而在正常细胞中则无毒性。而且，位置异构体5p，6c的体内抗癌活性进一步表明5、8 - O的6个异构体-二甲基酰基紫草素衍生物比其相应的2-异构体更具活性。因此，我们可以得出结论，紫草素侧链连接到5,8-二甲氧基-1,4-萘醌的位置与抗肿瘤活性有关。

  observed in vivo. Surprisingly, the dimethylated diacetyl derivatives with poor anticancer activity in vitro showed tumor‐inhibiting effects similar to paclitaxel without any toxicity in vivo. The anticancer activity of these derivatives is in agreement with their low ROS generation and alkylating capacity, emphasizing their potential as prodrugs. This strategy provides means to address the nonspecific

  为了最大程度地减少由于活性氧（ROS）的生成和萘达沙林环烷基化而产生的紫草素和链烷素的细胞毒性，设计了两个系列的新型核心骨架修饰的紫草素和链烷素衍生物。这些衍生物的构型和位置异构性不同（R-，S-，2-和6-异构体）以高对映体过量（> 99％ee）合成 ）。在体外，二甲基化衍生物的选择性显着高于母体紫草素，但在体内仍观察到一些副作用。令人惊讶的是，体外抗癌活性较差的二甲基化二乙酰基衍生物显示出与紫杉醇相似的肿瘤抑制作用，而在体内却没有任何毒性。这些衍生物的抗癌活性与其低ROS生成和烷基化能力相符，强调了其作为前药的潜力。该策略提供了解决萘他林类似物对正常细胞的非特异性细胞毒性的手段。
