Cytochalasans from the Endophytic Fungus sp. LE2: Their Structures, Antibacterial and NO Production Inhibitory Activities.

Six new cytochalasans-namely, aspergicytochalasins A-F (-)-together with five known analogs were isolated and characterized from the endophytic fungus sp. from the medicinal plant . The structures of the new compounds were established by NMR and MS methods as well as single crystal X-ray diffractions.
