Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis
ChemistryEurope, EarlyView.This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

New Phytologist, Volume 247, Issue 1, Page 233-248, July 2025.Summary Pathogenesis‐related (PR) proteins are diverse stress‐ or pathogen‐induced proteins. Some are associated with specialised metabolism, including proposed functions for anthocyanin biosynthesis. However, data are limited to a few angiosperm species, and the mode(s) of action are uncertain.

Characterization of Opioid Agonist Morphine Derivatives with Emphasis on Medicinal Chemistry
ChemMedChem, Volume 20, Issue 4, February 16, 2025.The aim of synthesizing new opioid compounds is to produce drugs that are more potent, less addictive, and have fewer side effects, such as respiratory depression and constipation. To achieve this, we evaluated the basicity, lipophilicity, and permeability of 30 opioid compounds, including 11 newly synthesized ones, to better understand the ...
