A rapid and improved route for synthesis of toxoflavin, an antibiotic and antitumor agent, is described. The method uses easily obtained materials and simple and practical reactions, including chlorination, condensation, and diazotization to produce toxoflavin in five steps with 14.2% yield and 98.6% purity (HPLC). This synthetic toxoflavin effectively inhibited β‐catenin/Tcf4 driven TOP‐luciferase
描述了一种快速且改进的合成毒素和抗肿瘤药毒素黄素的途径。该方法使用容易获得的材料和简单而实用的反应(包括氯化,缩合和重氮化),分五个步骤生产毒黄素,产率为14.2%,纯度为98.6%(HPLC)。这种合成的黄素毒素有效抑制β-catenin/ Tcf4驱动的TOP荧光素酶活性,IC 50小于0.5μM,并以剂量依赖性方式诱导结肠癌细胞死亡,IC 50为0.29μM。
