Popis: | Two new glucosidated indole-containing quinazoline alkaloids designated fumigatosides G (1) and H (2) were isolated from mangrove-derived fungus Aspergillus fumigatus SAl12, together with the known analogues fumigatoside B (3) and fumiquinazoline J (4). The planar structures of the new compounds were elucidated by HR-MS and NMR spectroscopic data analyses. The absolute configurations were determined by comparison of electronic circular dichroic (ECD) spectra with that of the known compound fumigatoside B and with the calculated ECD spectrum. All these indole-quinazoline compounds were tested for anti-bacterial and cytotoxic activities. |
