Bioactive Compounds
In addition to the physodic acid mentioned above, P. furfuracea also contains 2-hydroxy-4-methoxy-3,6-dimethyl benzoic acid, atranorin, oxyphysodic acid, and virensic acid. Of these compounds, atranorin showed the highest inhibition of proteolytic enzymes trypsin and porcine pancreatic elastase. Research suggests that the biosynthesis of both atranorin and physodic acid is influenced by the cooperation of epiphytic bacteria.
A number of sterol compounds have been identified from P. furfuracea, including ergosterol peroxide, ergosterol and lichosterol.

Famous quotes containing the word compounds:
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
