Abstract: Objective To study the effect of butenafine on ergosterol biosynthesis in fungi by measuring incorporation of nuclide. Methods The inhibitory effect of butenafine on ergosterol biosynthesis in whole-cell fungi was studied by measuring the incorporation of [1-14C] acetate into nonsaponifiable lipids( NSLs), while the effect in cell-free extracts was studied by measuring the incorporation of [2-14C] mevalonate into NSLs. Results The synthesis of ergosterol in fungi was significantly decreased after butenafine treatment, whereas the level of squalene was increased. The IC50 value of butenafine on ergosterol biosynthesis was 136.19 nmol/L in whole-cell study and 203.15 nmol/L in cell-free study. Conclusion The method to measure the incorporation of [1-14C]acetate and [2-14C] mevalonate into NSLs of fungi, which could indicate the level of squalene, might be widely used to study the mechanism of inhibitor of squalene epoxidase.
