*Please inquire the availability for this product. Usnic acid is a major metabolite from a number of lichen and fungal species and is perhaps one of the longest known microMSTl metabolites, first isolated in 1844. Usnic acid exhibits a broad range of biological activity; indeed it is easier to list the bioassays in which it does not exhibit activity. More often than not, potency is low and of limited value. Usnic acid is an important metabolite for dereplication in discovery research programs.
