Lobaric acid
Lobaric acid is a depsipeptide metabolite isolated from Stereocaulon lichen with antioxidant, antiproliferative, antiviral and enzyme inhibitory activities. Lobaric acid scavenges superoxide free radicals (IC50=97.9 μM) and inhibits cancer cell proliferation (EC50 of 15.2-63.9 μg/mL against leukemia, colorectal, gastric, breast, ovarian, prostate, pancreatic and lung cancer cell lines) . Lobaric acid inhibits protein tyrosine phosphatase 1B (PTP1B; IC50=0.87 μM for human recombinant enzyme) and 12 (S) -HETE produced by 12 (S) -lipoxygenase (IC50=28.5 μM) . Lobaric acid (250 μM) also reduced pathological changes in tobacco leaves infected with tobacco mosaic virus (TMV) .
