title: Eurotium (Aspergillus) repens metabolites and their biological activity.
abstract: Eurotium repens mycelium cultivated under static conditions was used to isolate and identify metabolities--echinulin, physcion, erythroglaucin, flavoglaucin and asperentin; the filtrate of the culture yielded asperentin 8-methylether. The broadest biological activity spectrum was displayed by asperentin which had antibacterial and antifungal effects and, at a concentration of 86 microgram/ml, caused 50% mor7 tality in Artemia saline larvae. The highest cytotoxicity towards HeLa cells was found in physcion which caused 50% growth inhibition at a concentration of 0.1 microgram/ml.
