Alternapyrone is a polyketide produced in A. oryzae heterologously expressing the A. solani-derived polyketide synthase gene alt5.

ChEBI: Alternapyrone is a member of the class of 2-pyranones that is 2H-pyran-2-one in which the hydrogens at positions 3, 4, 5 and 6 are replaced by methyl, hydroxy, methyl and (4E,6E,12E)-4,6,8,12,14-pentamethylhexadeca-4,6,12-trien-2-yl groups, respectively. It is a decaketide that is anabolized by a type I polyketide synthase in Alternaria solani. It has a role as a fungal metabolite. It is an olefinic compound, a member of 2-pyranones, a heteroaryl hydroxy compound and a decaketide.
