A rare glisoprenin analogue from an endophytic fungus sp. F1.

Glisoprenins are unique fungal polyisoprenepolyols with nine isoprene units from spp. Herein, glisoprenin G (), a new member of glisoprenins group, along with a biosynthetically related known analogue glisoprenin F (), were isolated and identified from an endophytic fungus, sp. F1, harboured in the roots of the Chinese medicinal plant . The chemical structure of showed the unusual loss of two isoprene carbon atoms and was determined by HRMS and NMR data. Compounds and showed moderate cytotoxic activity.
