Variolaric acid

Deriv Diacetylvariolaric acid, rhombic crystals (MeOH), mp 245-246 °C, from variolaric acid with AC2O-H2SO4... [Pg.351]

The best known depsidones are physodic acid, lobaric acid, norlobaridone, grayanic acid, alectoronic acid, diploicin, 4-0-methylphysodic acid, a-collatolic acid, lividic acid and variolaric acid. [Pg.10]

Brisdelli et al. (2013) investigated the effects of six lichen metabolites (diffractaic acid, lobaric acid, usnic acid, vicanicin, variolaric acid, protolichesterinic acid) on reactive oxygen species (ROS) level towards three human cancer cell lines, MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma) and HCT-116 (colon carcinoma). AU tested lichen compounds did not exhibit free radical scavenging activity using the l,l-diphenyl-2-picrylhydrazyl (DPPH) assay. The lichen metabolites did not significantly increase the intracellular ROS level and did not prevent oxidative injury induced by t-butyl hydroperoxide in tested cells. [Pg.118]
