Three undescribed compounds from Diaporthe biguttusis T-24, an endophytic fungus isolated from Ligularia fischeri
Natural product research(2024)
Abstract
Diaporthpyran A (1), diaporthester E (2) and diaporthester F (3), three new compounds along with four known compounds (4-7) were isolated from the crude extract of Diaporthe biguttusis T-24, an endophytic fungus isolated from Ligularia fischeri. The planar structures of compounds 1-3 including the relative and absolute configurations were elucidated on the basis of HRMS, NMR, J-based coupling constant analysis, CD, and calculated ECD analysis. In addition, compounds 1 and 3 were evaluated for their cytotoxic activities against four human cancer cell lines.
