Antimicrobial activities of mycotoxin MT81 and its structural derivatives.
Antimicrobial activities of mycotoxin MT81 and its acetylated, benzoylated and acetic acid derivatives were determined by zone inhibition method. MT81, acetylated MT81 and acetic acid MT81 exhibited sensitivity (31.25, 62.50, 62.50 micrograms/ml respectively) to all the test bacteria. Benzoylated-MT81 did not exhibit any activity even up to 1000 mcg/ml. MT81, its acetylated and acetic acid derivatives exhibited antifungal activity up to 62.5 micrograms/ml and 125.0 micrograms/ml respectively against test yeasts and other fungi. Benzoylated MT81 also exhibited antifungal activity but the degree was comparatively less.
