iodine-mediated quinone oxidation. The four synthetic compounds were evaluated for their in vitro cytotoxicactivities against six human cancer cells. 8-O-Methylfusarubin was the most potent analogue and displayed excellent cytotoxicactivity 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
