Abstract

Seven new dimeric tryptophol-related alkaloids (1–4, 5a, 5b , and 6) were isolated from solid cultures of the endophytic fungus Colletotrichum sp. SC1355. The structures and absolute configurations of these compounds were determined by NMR spectroscopic analyses in combination with quantum chemical calculations of NMR (GIAO) shifts and ECD spectra. This is the first report of fungus-derived tryptophol dimers. In addition, the isolated compounds were evaluated for acetylcholinesterase (AchE) inhibitory activity.
