Two new meroterpenoid pyrones, chevalone G (1) and aszonapyrone C (2), a new indole alkaloid, 7-chlorofischerindoline (3) and a new bicyclic brasiliamide, brasiliamide H (4), together with sixteen known compounds, 5-20 were isolated from the fungus Neosartorya hiratsukae. Their structures were established on the basis of spectroscopic evidence. The antibacterial activity and the cytotoxic activity of new compounds were evaluated.
