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 .
从真菌NRRL 35600中分离出一种新的异戊烯基化生物碱,即Amoenamide A()。此前,曾推测()是由Notoamide E()转化而来的Notoamide E4()的前体,而Notoamide E是该属真菌中异戊烯基化吲哚生物碱的关键前体。我们之前成功地从和MF297-2中分离出两对对映体,即Stephacidin A()和Notoamide B(),并预计在的培养物中存在其他对映体。在此,我们报道了从分离出的五个新对映体()以及一种新的代谢产物(),该代谢产物首次作为天然化合物被分离出来。
