Depsidones inhibit aromatase activity and tumor cell proliferation in a co-culture of human primary breast adipose fibroblasts and T47D breast tumor cells

open access: goldToxicology Reports, 2017
Naturally occurring depsidones from the marine fungus Aspergillus unguis are known to have substantial anti-cancer activity, but their mechanism of action remains elusive. The purpose of this study was to examine the anti-aromatase activity of two common

Lichen-Derived Diffractaic Acid Inhibited Dengue Virus Replication in a Cell-Based System [PDF]

open access: yesMolecules, 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
