Biological Context

Lecanoric acid is a naturally occurring depside polyphenol isolated from a variety of lichens.1 It is a potent antioxidant, surpassing ascorbic acid in a 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging assay (IC50s = 424.51 and 6.42 μg/ml for lecanoric and ascorbic acid, respectively).2 Lecanoric acid has antibacterial and antifungal activities with minimum inhibitory concentrations ranging from 0.5 to 1 mg/ml for a panel of fifteen microorganisms. In a cell viability assay, lecanoric acid exhibits antiproliferative activity against HeLa cells (IC50 = 123.97 μg/ml). Lecanoric acid also exhibits antidiabetic and hypolipidemic properties.1,3
