• addition, tanzawaic acid A (7) showed weak activity in agar diffusion assays at 50 µg/filter dics against Bacillus brevis, Mucor miehei, and Paecilomyces variotii, as well as cytotoxic effects against HeLaS3 cells at a concentration of 50 µg/mL. However, none of the other compounds showed bioactivity in
