- Two new dihydroxanthones, muroxanthenones D and E (1 and 2), were isolated from the fermentation products of the endophytic fungus Gliomastix murorum. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1 and 2 were tested for their anti-tobacco mosaic virus (anti-TMV) activity, and they exhibited activity with inhibition rates of 16.4 and 15.3%, respectively.
