Award-winning publication: Dibenzofurans and Pseudodepsidones from the Lichen Stereocaulon paschale Collected in Northern Quebec

Published in: Journal of Natural Products


The lichens that grow in northern Québec constitute an invaluable source of original bioactive substances as a result of the very unique environmental stress they are subjected to. The research conducted by Claudia Carpentier and her team is the first to detail the organic chemistry of the Stereocaulon paschale lichen and identify new molecules in the dibenzofurans family. Among the isolated compounds of the S. paschale lichen are new antimicrobial agents that fight some oral and periodontal diseases. These findings seem to indicate that the extreme growth conditions in Nunavik foster the biosynthesis of exceptional natural products.
