Sydowinin B

Description

Sydowinin B belongs to the class of organic compounds known as xanthones. These are polycyclic aromatic compounds containing a xanthene moiety conjugated to a ketone group at carbon 9. Xanthene is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring. Sydowinin B is found in Aspergillus austroafricanus. Sydowinin B is an extremely weak basic (essentially neutral) compound (based on its pKa).
