Actinotetraose hexatiglate is a unique tetrasaccharide with six tiglate esters that was isolated from an Amycolatopsis culture. The sugar is distinguished by a two-fold axis of symmetry and is a co-metabolite of quinaldopeptin, a cytotoxic antibiotic with anthelmintic activity. The biological role of this metabolite is not known but is suspected to lack antimicrobial activity.
