ABSTRACT
ABSTRACT Four compounds including beauvericin, parahydroxybenzaldehyde, indole-3-carboxylic acid and quinizarin were isolated from endophytic fungus Epicoccum nigrum and their cytotoxicity, antibacterial and antioxidant activity were evaluated. Beauvericin had remarkable activity against two Gram-negative strains (Bacillus cereus and Salmonella typhimurium) with respective MIC values of 3.12 and 6.25 µg/ml. All the compounds had weak cytotoxic effect on both normal and tumor cells. LC50 values ranged from 40.42 to 86.56 µg/ml, 31.87 to 86.57 µg/ml and 21.59 to 67.27 µg/ml on Vero cells, THP-1 and RAW 264.7 respectively. The present study showed that these compounds could be developed for the formulation of antioxidant-rich therapeutic diets and as a therapeutic agent against bacterial infections.
