This Korean study probes the ribosome and mitochondria relating to lichenoid compounds. The genus Catoplaca contains parietin:
Lichen Compounds / Chromatin Remodeling Inhibition
Lichen-forming fungus Caloplaca flavoruscens inhibits transcription factors and chromatin remodeling system in fungi. - PubMed - NCBI
'....Lichen extracts also have powerful antifungal and antibactieral activities, yet many lichen secondary metabolites have not been characterized, and their modes of action have not been defined....codes for gamma-glutamyl kinase, which catalyzes the first step of proline biosynthesis....
