MIC: 0.05 μg/62.5 μl to 3.1 μg/62.5 μl
Microorganisms can colonize a wide variety of medical devices, putting patients at risk for systemic and local infectious complications, including local-site infections, endocarditis, and catheter-related bloodstream infections. (+)-Usniacin is a secondary lichen metabolite that possesses antimicrobial activity against various planktonic gram-positive bacteria.
In vitro: (+)-Usniacin showed antimicrobial activity against the same microorganisms as that of acetone extract. Among the three analogues it was the most active one having quite low MIC values. Furthermore, (+)-Usniacin did not show any activity against A. hydrophila and B. cereus whereas (D)-usnic acid did. On the other hand, (+)-Usniacin was active against Y. enterocolitica whereas (D)-usnic acid was not active [1].
In vivo: No animal in-vivo study has been reproted so far.
Clinical trials: Trials carried out in volunteers showed that mouth-rinse with (+)-Usniacin preparations exerted a selective and long lasting action against S. mutans. The adherence of S. mutans to smooth surfaces was not increased by the presence of subinhibiting concentrations of (+)-Usniacin. These characteristics make (+)-Usniacin a suitable candidate for topical use in oral medicine [2].
