Common Name11,15-dihydroxy-6,8,20-trioxapentacyclo[10.8.0.0²,⁹.0³,⁷.0¹⁴,¹⁹]icosa-1,9,11,14,16,18-hexaen-13-one
DescriptionDe-O-methyldihydrosterigmatocystin, also known as dihydrodemethylsterigmatocystin, belongs to the class of organic compounds known as sterigmatocystins. These are a group of closely related fungal metabolites chemically characterized by a xanthone moiety fused to a dihydrodifurano or a tetrahydrodifurano moiety. The chemical difference among the various sterigmagocystins are the presence or absence of unsaturation at positions 2 and 3 of the difurano ring system, the substitution pattern on positions 6, 7, and 10 of the xanthone system and/or the substituent on position 3 of the difurano system. They are produced by Aspergilus spp. And Bipolaris spp. De-O-methyldihydrosterigmatocystin is an extremely weak basic (essentially neutral) compound (based on its pKa). Mycotoxin production by Aspergillus versicolor.
