Periconicins, two new fusicoccane diterpenes produced by an endophytic fungus Periconia sp. with antibacterial activity.

Two new fusicoccane diterpenes, named periconicins A (1) and B (2), with antibacterial activities have been isolated by bioassay-guided fractionation from an endophytic fungus Periconia sp., collected from small branches of Taxus cuspidata. The structures of the new compounds were determined by combined spectroscopic methods.
