Neocucurins A and B, two novel rearranged diterpenes from marine-derived fungus Neocucurbitaria unguis-hominis

Key Points

• The aim is to isolate and characterize novel diterpenes from the marine-derived fungus Neocucurbitaria unguis-hominis.
• Isolation of compounds from Neocucurbitaria unguis-hominis FS685
• Structural characterization using chemical analysis
• Neocucurin A features a unique 5/6/6/9 tetracyclic system
• Neocucurin B exhibits a bicyclo[8.3.1]tetradecane structure
