Breaking into nature's secret medicine cabinet: lichens – a biochemical goldmine ready for discovery

New Phytologist, Volume 246, Issue 2, Page 437-449, April 2025.
Summary Secondary metabolites are a crucial source of bioactive compounds playing a key role in the development of new pharmaceuticals. Recently, biosynthetic research has benefited significantly from progress on various fronts, including reduced sequencing costs, improved genome/metabolome mining strategies, and expanding tools/databases to compare ...

Circumscription of the genus Lepra, a recently resurrected genus to accommodate the "Variolaria"-group of Pertusaria sensu lato (Pertusariales, Ascomycota). [PDF]

PLoS ONE, 2017
Pertusarialean lichens include more than 300 species belonging to several independent phylogenetic lineages. Only some of these phylogenetic clades have been comprehensively sampled for molecular data, and formally described as genera.

Coumaroyl Iridoids and a Depside from Cranberry (Vaccinium macrocarpon) [PDF]

Journal of Natural Products, 2007
Cranberry (Vaccinium macrocarpon) juice has been used for urinary tract infections for approximately 50 years. Recent research suggests that this botanical blocks adherence of pathogenic E. coli to urinary tract cells, thus preventing infection. While current evidence indicates that proanthocyanidins are responsible for this activity, these compounds ...

p‐Terphenyl and Orsellinic Acid Derivatives from the European Polyporales Terana coerulea and Sparassis brevipes

Chemistry &Biodiversity, Volume 22, Issue 1, January 2025.
Abstract Investigation of the secondary metabolites of the solid‐state rice cultures from the European basidiomycetes Terana coerulea and Sparassis brevipes afforded three previously undescribed secondary metabolites identified as two p‐terphenyl derivatives (1 and 2) and one orsellinic acid congener (3) in addition to another known, isoeverninic acid (

New depside from Citrus reticulata Blanco

Natural Product Research, 2014
A new depside, named depcitrus A (1), and 31 known compounds were isolated from the peels, leaves and branch barks of Citrus reticulata Blanco. Methylation of the high polarity fractions from the branch barks and peels gave one new methylated compound named depcitrus B (14) and five known compounds.

Methyltransferase Domain‐Focused Genome Mining for Fungal Polyketide Synthases

Small Methods, Volume 8, Issue 11, November 20, 2024.
Genome mining is performed with a focus on the substrate‐binding amino acid residues in the C‐methyltransferase domains of fungal nonreducing polyketide synthases (NR‐PKSs). An NR‐PKS designated as AsbPKS is discovered and found to be responsible for the formation of anhydrosclerotinin B (1), the biosynthesis of which adopts a previously unreported ...
