Overview
(–)-Mycousnine is a microbial metabolite and derivative of Usnic Acid originally isolated from M. nawae that has antibacterial and antifungal activities. It is active against the Gram-positive bacteria B. subtilis, K. rhizophila, and S. aureus (MICs=4, 8, and 4 g/ml, respectively) but not the Gram-negative bacteria E. coli, S. typhimurium, and K. pneumoniae (MICs=>128 g/ml for all).2 (–)-Mycousnine is also active against the fungi T. mentagrophytes, T. rubrum, and C. albicans (MICs=25, 25, and 100 μg/mL, respectively).
