A Photochemical Entry to Depsides: Synthesis of Gustastatin. [PDF]
ChemInform, 2005 Herein, we propose a modular and general strategy to construct orcinol-type depsides based on the photolysis of functionalized benzodioxinones (I). Notably, resorcinylic esters are obtained without competing isocoumarin (II) formation, exemplified by the first total synthesis of gustastatin in 10 steps from commercially available trihydroxybenzoic acid.

Lichen and Its Microbiome as an Untapped Source of Anti-Biofilm Compounds. [PDF]
Chem BiodiversLichens and their associated fungi give rise to the evaluation of several extracts and compounds against biofilms. ABSTRACT Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi ...

Identification of Anziaic Acid, a Lichen Depside from Hypotrachyna sp., as a New Topoisomerase Poison Inhibitor [PDF]
, 2013 Topoisomerase inhibitors are effective for antibacterial and anticancer therapy because they can lead to the accumulation of the intermediate DNA cleavage complex formed by the topoisomerase enzymes, which trigger cell death.

Evaluation of herbicidal potential of depsides from Cladosporium uredinicola, an endophytic fungus found in Guava fruit [PDF]
, 2012 Two natural products produced by Cladosporium uredinicola, an endophytic fungus isolated from guava fruit, were evaluated for their effects on photosynthesis.
