Isolation of amoenamide A and five antipodal prenylated alkaloids from NRRL 35600.

A new prenylated alkaloid, Amoenamide A (), was isolated from the fungus NRRL 35600. Previously, was postulated to be a precursor of Notoamide E4 () converted from Notoamide E (), which was a key precursor of the prenylated indole alkaloids in the fungi of the genus . We previously succeeded in the isolation of two pairs of antipodes, Stephacidin A () and Notoamide B (), from and MF297-2 and expected the presence of other antipodes in the culture of . We here report five new antipodes () along with a new metabolite (), which was isolated as a natural compound for the first time, from .
