Abstract: Usnic acid (UA) is a commercially available lichen metabolite. Its biological activity is diverse. Its broad occurrence in various lichen species, simple isolation procedure, and high optical purity of the isolated product make it promising as a base for developing novel pharmaceuticals. To date, scientific progress has made it possible to expand the scope of applications of UA and comprehend the biological mechanisms mediating its action. This review of the biological activity of UA and its derivatives summarizes publications of the recent decade. New data on the mechanisms of UA action on living organisms are discussed, and ways to modify its biological activity by altering its chemical structure and to control its bioavailability are considered. Special attention is paid to prospects of using semisynthetic UA derivatives as pharmacological agents. Data on the influence of the enantiopurity of UA on its biological activity are analyzed. The first part of the review is dedicated to UA biosynthesis and the biological action of UA and its derivatives on unicellular organisms.
