Journal of Chemistry, Volume 2022, Issue 1, 2022., 2022 A new hopan‐type triterpenoic peracid, tinctoride A (1), together with three known compounds, zeorin (2), 6β,22‐dihydroxyhopane (3), and ergosterol peroxide (4), was isolated from Parmotrema tinctorum (Despr. ex Nyl.) Hale. Their chemical structures were identified by extensive 1D and 2D NMR analysis and high‐resolution mass spectroscopy and compared ...

Ecology and Evolution, Volume 11, Issue 24, Page 18615-18632, December 2021., 2021 We investigate species boundaries and the potential for micro‐endemism for a charismatic genus of lichen fungi occurring in Baja California. Genome‐scale data support high species‐level diversity, along with high levels of endemism, while highlighting the problem of delimiting species, particularly in groups with complex, recent phylogeographic ...

Climate‐specific biosynthetic gene clusters in populations of a lichen‐forming fungus
Environmental Microbiology, Volume 23, Issue 8, Page 4260-4275, August 2021., 2021 Summary Natural products can contribute to abiotic stress tolerance in plants and fungi. We hypothesize that biosynthetic gene clusters (BGCs), the genomic elements that underlie natural product biosynthesis, display structured differences along elevation gradients.

A computational insight into acetylcholinesterase inhibitory activity of a new lichen depsidone [PDF]
, 2015 Acetylcholinesterase (AChE) inhibitors are yet the best drugs currently available for the management of Alzheimer's disease. The recent phytochemical investigation has led to the isolation of a new depsidone 1 with moderate AChE activity (1 mu g).

Cytotoxicity of Alkyl Derivatives of Protocetraric Acid
Orbital: The Electronic Journal of ChemistryThe protocetraric acid (1) is a depsidone produced by countless species of lichens and has shown potential biological activity. In this work, we evaluated through the sulforhodamine B (SRB) assay the cytotoxic activity of seven alkyl ether derivatives ...
