    Product Description

    Brassicasterol is a phytosterol found in canola and rapeseed oils, marine algae, and shellfish.1 It inhibits recombinant sterol Δ24-reductase with a Ki value of 42.7 μM in vitro. Brassicasterol increases accumulation of desmosterol, a cholesterol precursor and substrate of sterol Δ24-reductase, and inhibits cholesterol formation in HL-60 cells in a dose-dependent manner. It also inhibits the hemolytic activity of pneumolysin from S. pneumoniae without affecting bacterial growth at concentrations up to 1,000 μg/ml.2

    WARNING This product is not for human or veterinary use.
