OSMAC strategy could increase the kind of wortmannilactones. Three new wortmannilactones, wortmannilactones I1-I3, were isolated from medium of Talaromyces wortmannii. Their structures were assigned by IR, HRESIMS, NMR and ECD. These new wortmannilactones exhibit selective inhibitory activity against NADH-fumarate reductase.
