Anziaic acid is a depside found in lichens. It gives a red reaction in the C test. The two phenolic rings have a pentyl side chain. It is an ester dimer of olivetolic acid.^[1]

Anziaic acid works as an antibacterial compound by inhibiting topoisomerase.^[2]^[3]

Production

Anziaic acid has been artificially produced from olivetolic acid by benzylation of the O-phenol positions, and then condensing with trifluoroacetic anhydride.^[1]

Properties

Anziaic acid is colourless. It can be dissolved in ethanol, ethanol-water mixture, or cyclohexane-benzene mixture.^[1]

Perlatolic acid, dihydropicrolichenic acid, 2'-O-methylanziaic acid, 2-O-methylperlatolic acid, 2'-O-methylperlatolic and planaic acid are derivatives of anziaic acid, where a methyl group replaces a hydrogen in some of the hydroxy positions on the rings.^[1]

Occurrence

Anziaic acid is found in Parmeliaceae including Hypotrachyna,^[2] Stereocaulon,^[4] and Cetrelia,^[5]
