Aspeverin, a new alkaloid from an algicolous strain of Aspergillus versicolor

摘要

A novel carbamate- and cyano-containing alkaloid, aspeverin (1), was isolated from the culture of an algicolous Aspergillus versicolor strain (dl-29). The structure and absolute configuration were unambiguously identified by NMR, IR, ECD, and mass spectrometric methods as well as quantum chemical calculations. 1 exhibited potent bioactivities against some marine-derived organisms.
