Brominated Depsidones from <i>Acarospora gobiensis</i>, a Lichen of Central Asia

Abstract

Two new antimicrobial polysubstituted brominated depsidones, acarogobien A ( 1 ) and acarogobien B ( 2 ), were isolated from the lichen Acarospora gobiensis . Their structures were established by 1 H and 13 C NMR, MS, IR, and UV spectroscopy.
