Norstictic acid, physodic acid, evemic acid, usnic acid, salazinic acid, fumar-protocetraric acid, protocetraric acid, atranorin and zeorin isolated from different lichen species are relatively strong antioxidant, antimicrobial and anticancer agents (Kosanic et al. 2010, 2013, 2014 Manojlovic et al. 2012 Rankovic et al. 2014). [Pg.20]

Parmelia saxatilis species. Antioxidant activities of these isolated metabolites were evaluated by free radical scavenging, superoxide anion radical scavenging and reducing power. As a result of the study, usnic acid had stronger antioxidant activity than salazinic acid and protocetraric acid in all used tests. [Pg.121]

Protocetraric acid (424) has been synthesized by Sala and Sargent (277) by dibromination of the synthetic depsidone (420) and hydrolysis of the product. The resultant diol (421) was partially demethylated and converted into the acetonide (422), This on oxidation with pyridinium chlorochromate and deprotection gave the methyl 0-methylprotocetrarate (423) which on demethylation gave protocetraric acid (424). [Pg.190]

Succinprotocetraric acid, from Parmelia reptans and Chondropsis semi-viridis (77), and malonprotocetraric acid from Parmotrema conformatum (208), are derivatives of protocetraric acid (424) in which the benzyl alcohol... [Pg.191]

A number of depsidones in the meta series are aldehydes fumarprotoce-traric acid, stictic acid, norstictic acid (72), constictic acid, (73),pannarin, physodalic acid, protocetraric acid, psoromic acid, salazinic acid, and virensic acid. They react with / -phenylenediamine to give yellow to red condensation products (P+ substances). [Pg.510]
