New Monordens Produced by Amidepsine-producing Fungus Humicola sp. FO-2942

Abstract

Based on UV spectrum-guided purification, new monordens C, D and E, known monordens A (radicicol) and B and 5-O-methylsclerone were isolated from the fermentation broth of amidepsine-producing Humicola sp. FO-2942 by solvent extraction, silica-gel column chromatography, ODS column chromatography and HPLC. All monordens cause the cell cycle arrest at G1 and G2/M phases in Jurkat cells. But among them, monordens A and E show antifungal activity only against Aspergillus niger.
