Two new tricyclic sesterterpenes, fusaprolifins A and B ( 1 and 2 ), and three new 2 H‐ pyran‐2‐one derivatives, prolipyrones A – C ( 3 – 5 ), were isolated and characterized from Fusarium proliferatum MA‐84, an endophytic fungus obtained from the fresh tissue of the marine mangrove plant Bruguiera sexangula. In addition, two known sesterterpenes, terpestacin ( 6 ) and fusaproliferin ( 7 ), and one known 2 H ‐pyran‐2‐one derivative, gibepyrone D ( 8 ), were also identified. The structures of these compounds were elucidated by detailed spectroscopic analyses. Fusaprolifin A ( 1 ) showed moderate activity against brine shrimp ( Artemia salina ), with a lethality rate of 49.5% at 100 μg/ml, while fusaprolifin B ( 2 ) showed weak activity.
