Abstract

One new quinoline alkaloid (1), two new bisabolane-type sesquiterpene derivatives (2 and 3), and a new natural product (4) along with ten known compounds (514) were isolated from the deep sea-derived fungus Aspergillus sp. SCSIO06786 which cultured on solid rice medium. Three new structures were elucidated by analysis of 1D/2D NMR data and HR-ESI-MS. The absolute configurations of 2 and 3 were established by comparison of the experimental and reported ECD values. Compounds 11–13 exhibited moderate selective inhibitory activities against the tested pathogenic bacteria with MIC values among 3.13–12.5 μg/mL.
