Synthesis of a new class of aminocyclitol analogues with the conduramine D-2 configuration

open access: yesBeilstein Journal of Organic Chemistry, 2010
A new class of aminocyclitol derivatives with the bicyclo[4.2.0]octane skeleton was synthesized starting from cyclooctatetraene. Photooxygenation of trans-7,8-diacetoxy- and cis-7,8-dichlorobicyclo[4.2.0]octa-2,4-diene afforded the bicyclic endoperoxides.

Recent Trends in Metabolomics by NMR Spectroscopy

open access: yesAngewandte Chemie International Edition, EarlyView.
AI tools were applied to analyze more than 5 000 publications indexed in Scopus (2018–2025), identifying key trends and research directions in NMR‐based metabolomics. The artificial intelligence‐assisted workflow classified papers into six main fields of application, human health, food and nutrition, veterinary science, plants, environment, and ...

The Impact of Phytases on the Release of Bioactive Inositols, the Profile of Inositol Phosphates, and the Release of Selected Minerals in the Technology of Buckwheat Beer Production

open access: yesBiomolecules, 2020
A relatively high concentration of phytate in buckwheat malt, and the low activity of endogenous buckwheat phytases, both of which limit the effective use of substrates (starch, proteins, minerals) for fermentation and yeast metabolism, gives rise to the

A Practical and Flexible De Novo Synthesis of Deoxygenated Carbasugars and Their Cyclitol Epoxides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A de novo synthesis route comprising enantioselective Brown crotylation and ring‐closing metathesis as the key steps enables the synthesis of a‐ and b‐carba‐paratose, a‐ and b‐carba‐colitose as well as four configurational deoxycyclophellitol isosteres.

Almond (Amygdalus communis L.) Peptides Improve Scopolamine‐Induced Learning and Memory Impairment in Mice

open access: yesFood Safety and Health, EarlyView.
Figure Schematic showing the improvement of almond peptides on learning and memory impairment induced by scopolamine in mice. Almond peptides (APs) could improve the learning and memory in scopolamine‐induced mice by maintaining cholinergic system homeostasis and regulating Nrf2/Keap1 signaling pathway, via activating the Nrf2 transcription factor and ...
