Their chemical structures were established on the basis of spectroscopic analysis (IR, 1D NMR, 2D NMR, Mass, etc.) and by chemical means. A probable biosynthetic pathway of compound 1 was also proposed. Preliminary investigation with the new compound showed potent activity against a series of fungal pathogens.
