Abstract: Fusagerins A-F(1-6), six new alkaloids including a unique one with the rare a-(N-formyl) carboxamide moiety(1), a hydantoin(imidazolidin-2, 4-dione) derivative(2), and four fungerin analogues(3-6), were isolated from the crude extract of the fungus Fusarium sp. , together with the known compound fungerin(7). Compound 2 was isolated as a racemate and further separated into two enantiomers on a chiral HPLC column. The structures of 1-6 were determined mainly by NMR experiments, and the absolute configuration of 1 and 2 was assigned by electronic circular dichroism(ECD) calculations. Compound 7 showed antibacterial activity against Staphylococcus aureus and Streptococcus pneumoniae, and weak cytotoxicity against the T24 cells.

Key words: Fusarium sp., Alkaloids, Structure elucidation, Configuration determination
