ABSTRACT
A rare hexacyclic oxindole alkaloid, speradine F (1), together with two novel tetracyclic oxindole alkaloids, speradines G (2) and H (3), were isolated from the marine-derived fungus Aspergillus oryzae. Their structures were determined by spectroscopic methods and X-ray diffraction analysis. This study is the first report on cyclopiazonic acid (CPA)-type alkaloids with a hexacyclic skeleton.
