(–)-Mycousnine

(Synonyms: Mycousunin)

(–)-Mycousnine is a microbial metabolite and derivative of Usnic Acid (HY-N0656) 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).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
