Circumdatin A, produced by Aspergillus sp., was first reported in 1999 by Rahbaek and colleagues, University of Copenhagen, Denmark. The structure of circumdatin A was revised as a unique oxepine in 2008 using X-ray crystallography. Lack of availability has prevented investigation of its biological activity to date.
