description | Two triterpenes, ganoaustralins A (<b>1</b>) and B (<b>2</b>), featuring unprecedented 6/6/6/5/6 scaffolds were isolated from the fruiting bodies of the mushroom <i>Ganoderma australe</i>. The structures were determined by extensive NMR and HRESIMS spectroscopic analysis. The absolute configuration of the C-25 in ganoaustralin A was assigned by the phenylglycine methyl ester (PGME) method. The relative and absolute configurations of the polycyclic backbones were determined by NMR and ECD calculations, respectively. The plausible biosynthetic pathways of ganoaustralins A and B were proposed. Ganoaustralin B showed weak inhibition against <i>β</i>-secretase 1. |
