Ilicicolin F is a fungal metabolite that has been found in Fusarium and has diverse biological activities. It inhibits T. vivax alternative oxidase and the E. coli ubiquinol oxidase cytochrome bo (IC50s=0.43 and 0.37 μM, respectively) but not the E. coli ubiquinol oxidase cytochrome bd (IC50=85 μM).2 Ilicicolin F is active against the fungi A. fumigatus and C. albicans (MICs=1.66-3.33 and 6.66-13.33 μg/mL, respectively). It is cytotoxic to HeLa cells with an EC50 value of 0.003 μg/mL.
