Lichenicolins A and B, New Bisnaphthopyrones from an Unidentified Lichenicolous Fungus, Strain LL-RB0668

The Journal of Antibiotics volume 58, pages 731–736 (2005)Cite this article

Abstract

Lichenicolous fungus LL-RB0668 was isolated from a processed lichen thallus on a modified Lilly-Barnett solid medium. Two new bisnaphthopyrone compounds, lichenicolins A (1) and B (2), were isolated from the culture broth of this organism fermented on a rice-based solid medium. These results demonstrate that lichen-associated fungi potentially are a good resource for new bioactive natural products for current screening programs.
