Four new depsides in Origanum dictamnus methanol extract
, 2013 We herein describe the identification of four new depsides present in methanol extract of Origanum dictamnus. O. dictamnus’ (dittany) aerial parts methanol extract was subjected to semi-preparative RP-HPLC fractionation followed by identification of ...

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.

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 ...

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.

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 ...

CNS Neuroscience &Therapeutics, Volume 30, Issue 11, November 2024.Because of CSF biomarkers identified by neuroimaging techniques in the middle or late stages of AD, blood is considered as the novel biomarker resource for the early diagnosis of AD. The accurate alternations in blood could predict AD. This paper discusses potential blood‐based biomarkers identified by proteomics and metabolomics and future research ...

Inhibition of Photosystem II of Spinach by Lichen-derived Depsides
Bioscience, Biotechnology, and Biochemistry, 1998 Barbatic acid, a lichen-derived depside, inhibited oxygen evolution in spinach thylakoid membranes. It also affected parameters of Chl fluorescence, (Fm'-F)/F and Fv/Fm. Using specific donors and acceptors of electrons, we found two sites of inhibition in the PS II complex.
