Macularin
Macularin is a naturally occurring chemical compound classified as a depsidone. It is a type of secondary metabolite found in certain species of lichens, notably those belonging to the genus *Stereocaulon*. The chemical structure of macularin is characterized by a dibenzofuran core with two ester linkages.
This compound was first isolated and identified in the early 21st century. Research into macularin has primarily
Macularin is produced by lichens as part of their metabolic processes, often in response to environmental stimuli.
