Fenpropimorph is an effective fungicide that hampers the sterol pathway by obstructing key enzymes. In yeast, it specifically targets Δ8-Δ7-sterol isomerase at lower concentrations, while at higher concentrations, it blocks Δ14-sterol reductase, thereby impeding the production of ergosterol. Additionally, Fenpropimorph demonstrates the ability to hinder sterol synthesis in specific plants and mammalian cells.
