Spiro fused diterpene-indole alkaloids from a creek-bottom-derived Aspergillus terreus

Org Lett. 2013 Aug 16;15(16):4186-9. doi: 10.1021/ol401891z. Epub 2013 Aug 7.

Abstract

Four metabolites, teraspiridoles A-D (2-5), formed from the merger of a diterpene and modified indole scaffold were obtained from an Aspergillus terreus isolate. The structures and absolute configurations of these natural products were established using NMR, mass spectrometry, Marfey's method, VCD, and ECD data. Teraspiridole B (3) exhibited weak inhibition of planaria regeneration/survival.
