Synthesis of glycosyl hydroperoxides derived from 2,3,4,6-tetra-O-benzyl-d-glucopyranose and 2,3,4,6-di-O-isopropylidene-d-mannofuranose was performed via a Schmidt's imidate intermediate with hydrogen peroxide in an ethyl ether solution in the presence of an acid catalyst. Separation of the α- and β-anomers of the glycosyl hydroperoxides was achieved by chromatography.

Phanerochaete chrysosporium (Pc), is a prominent lignin-degrading fungus which serves as an important source for lignin-degrading enzymes (LDEs). The present study was focused on a detailed in silico analysis and gene expression patterns of lignin peroxidases (PcLiPs), which is a significant class of LDEs. In spite of extensive research on P.

Natural stilbene compounds, such as resveratrol and pterostilbene, have been focused on owing to their diverse biological activities associated with antioxidant, anti-inflammatory, and anti-aging properties. However, their low water solubility limits their advanced applications. In this study, we investigated the protective effects of selected stilbene compounds (resveratrol, oxyresveratrol, gnetol, piceatannol, and pterostilbene) and their water-soluble derivatives (piceid, resveratrol polysaccharide, pterostilbene trisaccharide, and pterostilbene polysaccharide) against UVA-, UVB irradiation, tertiary-butyl hydroperoxide (t-BuOOH)- and hydrogen peroxide (HO)-induced injury in human epidermal cells.

The membrane-integrated NADPH oxidases DUOX1 and DUOX2 are recruited to the apical plasma membrane in epithelial cells to release hydrogen peroxide, thereby playing crucial roles in various functions such as thyroid hormone synthesis and host defense. However, it has remained unknown about the molecular mechanism for apical sorting of DUOX1 and DUOX2. Here we show that DUOX1 and DUOX2 are correctly sorted to the apical membrane via the membrane-spanning DUOX maturation proteins DUOXA1 and DUOXA2, respectively, when co-expressed in MDCK epithelial cells.
