Visnagin is a polyketide synthase-derived furanochromone originally isolated from A. visnaga that has diverse biological activities.1,2,3,4,5 It inhibits the germination and growth of ryegrass (IC50s = 502 and 214 μM, respectively).2 Visnagin (100 μg/ml) is cytotoxic to, and induces apoptosis in, HT-144 melanoma cells.3 It reduces LPS-stimulated increases in the secretion of TNF-α, IL-1β, and IFN-γ in BV-2 microglial cells when used at concentrations of 50 and 100 μM.4 Visnagin (25 mg/kg) protects against cardiomyopathy induced by doxorubicin in mice.5
