The structure and relative stereochemistry of a new type of indoloditerpenoid designated as emindole PA 1, isolated from the mycelium of Emericella purpurea, along with the sesterterpene variecolin recently isolated from Emericella variecolor, has been confirmed by a chemical and spectroscopic investigation. During a search for fungal indoloditerpenoids, two components, one with a bluish and the other a reddish colouration when sprayed with van Urk reagent were detected on TLC, in the dichloromethane extract of Emericella purpurea Samson & Mouchacca, strain IFO 30849, which was isolated from Egyptian desert soil. The former compound was identical with variecolin, a sesterterpene recently isolated from E. variecolor Berkeley & Broome which was shown to be an angiotensin II receptor binding inhibitor, whereas the latter was a new compound which we designated as emindole PA 1. The molecular formula of 1 was confirmed by high resolution electron-impact ionization (EI) mass spectrometry.
