Genome Mining-Guided Discovery of Two New Depsides from Talaromyces sp. HDN1820200 [PDF]
Marine DrugsDepsides and their derivatives are a class of polyketides predominantly found in fungal extracts. Herein, a silent nonreducing polyketide synthase (TalsA)-containing gene cluster, which was identified from the Antarctic sponge-derived fungus Talaromyces ...

Lichen-Derived Diffractaic Acid Inhibited Dengue Virus Replication in a Cell-Based System [PDF]
Molecules, 2023 Dengue is a mosquito-borne flavivirus that causes 21,000 deaths annually. Depsides and depsidones of lichens have previously been reported to be antimicrobials. In this study, our objective was to identify lichen-derived depsides and depsidones as dengue

Synthesis of Further Lichen Depsides
Australian Journal of Chemistry, 1993 The unambiguous total synthesis of 18 lichen depsides has been achieved by the condensation of an appropriately substituted orsellinic acid and protected phenol in the key step, followed by subsequent deprotection and/or secondary reduction. The natural occurrence of the first meta-depside involving substitution at the 5??-position of the B-ring has ...
