Polyporic acid is a terphenyl benzoquinone compound first identified by German chemist Stahlschmidt from a mycelial culture of the fungus species Hapalopilus nidulans in 1877.[1][2] This chemical, present at 20–40% of the fresh weight of the fruit bodies,[3] inhibits the enzyme dihydroorotate dehydrogenase.[4] It is found in other mushrooms, but in much lower amounts.[4] Polyporic acid has some antifungal[5] and antibacterial activity.[6] It has been shown to be an intermediate in the biosynthesis of allantofuranone, a gamma-lactone antibiotic from the black rot fungus Allantophomopsis lycopodina.[7]
