Gymnoascolide A is a fungal metabolite originally isolated from G. reessii that has fungicidal and vasodilatory activities.1,2 It is active against the phytopathogenic fungus S. nodorum (MIC = 13 µg/ml) but not C. albicans, B. subtilis, or the ruminant pathogenic nematode H. contortus in an agar diffusion assay.1,2 Gymnoascolide A (1 µM) inhibits calcium-induced contractions in isolated rat aortic rings.2
