iodine-mediated quinone oxidation. The four synthetic compounds were evaluated for their in vitro cytotoxic activities against six human cancer cells. 8-O-Methylfusarubin was the most potent analogue and displayed excellent cytotoxic activity against MCF-7 breast cancer cells with an IC50 value of 1.01 μM with no cytotoxic effect on noncancerous Vero cells, which could potentially be a promising lead compound
据报道,一种简单而统一的合成方法是合成四个相关的吡喃并萘醌天然产物,例如8-O-甲基呋喃丁酮,8-O-甲基脱水呋喃丁酮,呋喃丁酮和脱水呋喃丁酮。关键的合成特征包括先有的Diels-Alder环加成反应可组装萘骨架,选择性甲酰化和乙酰化反应以及分子内乙缩醛化反应可构建吡喃环。操纵萘醌核心的氧化态以构建两种类似物,富沙红素和脱水富沙红素。这项工作还突出了羟甲基在选择性高价碘介导的醌氧化中的空前指导作用。评价了四种合成化合物对六种人类癌细胞的体外细胞毒性活性。
