Cytochalasins from Xylaria sp. CFL5, an Endophytic Fungus of Cephalotaxus fortunei

Three previously undescribed cytochalasins, named xylariasins A‒C ( 1 ‒ 3 ), together with six known ones ( 4 ‒ 9 ) were isolated from Xylaria sp. CFL5, an endophytic fungus of Cephalotaxus fortunei . The chemical structures of all new compounds were elucidated on the basis of extensive spectroscopic data analyses and electronic circular dichroism calculation, as well as optical rotation calculation. Biological activities of compounds 1 , 4 ‒ 9...
