Antifungal Halogenated Cyclopentenones from the Endophytic Fungus Saccharicola bicolor of Bergenia purpurascens by the One Strain-Many Compounds Strategy

Phytopathogenic fungi have been considered as being an enormous threat in the agricultural system. In our search of new antifungal natural products, nine new halogenated cyclopentenones, bicolorins A-I (1-3, and 5-10), along with three known cyclopentenones (4, 11, and 12) were isolated from the endophytic fungus Saccharicola bicolor of Bergenia purpurascens by the one strain-many compounds strategy. Their structures and absolute configurations...
