(+)-Isoaltenuene is heptaketides with antiviral activity from endolichenic fungal strains Nigrospora sphaerica. Also, it is useful for the synthesis of Alternaria toxins. Also, it is derived from Trifluoromethanesulfonic Acid 7-Methoxy-2,2-dimethyl-4-oxo-4H-1,3-benzodioxin-5-yl Ester (T790530), which is an intermediate for the synthesis of the precursor compound for Altenuene (A575740), a toxin isolated from the fungus Alternaria tenuis.
