Anhydroophiobolin A is an ophiobolin fungal metabolite that has been found in C. heterostrophus fermentation broths. It is cytotoxic to HepG2 and K562 cancer cells (IC50s = 55.7 and 39.5 μM, respectively).
3-Anhydroophiobolin A is the dehydrated analogue of ophiobolin A and is a major member of the ophiobolin complex of phytotoxic metabolites produced by many species of the genus Bipolaris. Like all ophiobolins, 3-anhydroophiobolin A possesses a broad biological profile with antibacterial, antifungal, antitumour, herbicidal and nematocidal activities.
