Common Name1-[3,10-dihydroxy-12-(2-hydroxypropyl)-2,6,7,11-tetramethoxy-4,9-dioxoperylen-1-yl]propan-2-yl benzoate
DescriptionCalphostin B, also known as ucn 1028 b, belongs to the class of organic compounds known as perylenequinones. These are heterocyclic compounds characterized by two 8-hydroxy-1,4-dihydronaphthalen-1-one moieties joined together one or two CC-bonds. 1-[3,10-dihydroxy-12-(2-hydroxypropyl)-2,6,7,11-tetramethoxy-4,9-dioxoperylen-1-yl]propan-2-yl benzoate is found in Cladosporium cladosporioides. 1-[3,10-dihydroxy-12-(2-hydroxypropyl)-2,6,7,11-tetramethoxy-4,9-dioxoperylen-1-yl]propan-2-yl benzoate was first documented in 1999 (PMID: 10450923). Based on a literature review very few articles have been published on Calphostin B.
