Natural Product Identification
Common NameEmericellin
DescriptionEmericellin, also known as variecoxanthone b, belongs to the class of organic compounds known as 4-prenylated xanthones. These are organic compounds containing a C5-isoprenoid group linked to a xanthone moiety at the 4-position. Xanthone is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring that carries a ketone group. Emericellin is an extremely weak basic (essentially neutral) compound (based on its pKa). Emericellin is found in Aspergillus nidulans, Aspergillus quadrilineatus, Aspergillus rugulosus, Aspergillus variecolor strain CBS 135-55, Emericella nidulans var.acristata and Aspergillus striatus. Emericellin was first documented in 2007 (PMID: 17277172). A xanthone that is xanthen-9-one bearing hydroxymethyl, 3,3-dimethylallyloxy, methyl, 3,3-dimethylallyl and hydroxy groups at positions 1, 2, 3, 5 and 8 respectively (PMID: 21351751).
