| Research Abstract |
The notoamides are a family of prenylated indole alkaloids produced by the marine-derived Aspergillus sp. To understand the molecular bases for their biogenesis, we conducted a precursor incorporation experiment using synthetic, [13C,15N]-notoamide S. Unfortunately, compounds containing a bicycle[2.2.2]diazaoctane core, such as notoamides B and stephacidin A, were not ilolated from this feeding experiment. We isolated, however, notoamide S from cultures of Aspergillus sp. It is suggested that notoamide S is involved in biosynthesis of notoamides. Therefore, we think that notoamide S must be biosynthetic precursor.
