Lichens: might be considered as a source of gastroprotective molecules? [PDF]
, 2013 Indexación: Web of Science; ScieloABSTRACT Lichens are symbiotic relationship between fungi and algae or cyanobacteria. Secondary metabolites from lichens are known as lichen substances.

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Introduction. Lichens, due to the presence of own secondary metabolites such as depsidones and depsides, became a promising source of health‐promoting organisms with pharmacological activities. However, lichens and their active compounds have been much less studied.

Secalonic acid A from Pseudoparmelia sphaerospora (Nyl.) Hale and P. hypomilta (Fée) Hale (Parmeliaceae) [PDF]
, 1995 Secalonic acid A, a yellow pigment from fungal metabolism, was isolated from the lichens Pseudoparmelia sphaerospora and P. hypomilta. From P. sphaerospora was also isolated the depsidone hypostictic acid.

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.

Theoretical Study on the Antioxidant Activity of Natural Depsidones [PDF]
ACS Omega, 2020 Depsidones are secondary metabolites in lichens with a range of potential health benefits. Among others, these compounds are believed to exhibit high hydroxyl radical and superoxide scavenging abilities, warranting a detailed investigation of their antioxidant properties.

Lichen specific thallus mass and secondary compounds change across a retrogressive fire-driven chronosequence [PDF]
, 2012 In the long-term absence of major disturbances ecosystems enter a state of retrogression, which involves declining soil fertility and consequently a reduction in decomposition rates.
