C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

MurNAc‐Based Electrophilic Inhibitors of O‐Acetylpeptidoglycan Esterase (Ape): Design, Synthesis, and Kinetic Evaluation

open access: yesChemistry – A European Journal, EarlyView.
A series of N‐acetylmuramic acid (MurNAc)‐based electrophilic inhibitors targeting Ape esterase was synthesized. Their inhibitory potency ranged from micromolar to submillimolar. The study probed binding contributions of stem peptide extension, replacing the anomeric methyl group with a benzyl, and α‐fluorination of the carbonyl to enhance ...

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

The role of acyl carrier protein in strawberry fruit ripening [PDF]

open access: yes, 2000
Strawberry (Fragaria ananassa) is an economically important soft fruit that is highly valued as a fresh product and flavouring. During ripening, strawberry fruits undergo a number of physiological changes affecting colour, texture and flavour.

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Phytochemical composition and cultivar‐dependent variation in colored lettuce (Lactuca sativa) and their α‐amylase inhibitory activity

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study investigated cultivar‐dependent variation in the phytochemical composition of lettuce (Lactuca sativa) using liquid chromatography–tandem mass spectrometry (LC–MS/MS) profiling and high‐performance liquid chromatography (HPLC) quantification, with a focus on enzyme inhibitory activity. RESULTS Significant differences were

Biochemical studies on plant glycerol-3- phosphate acyltransferase [PDF]

open access: yes, 2003
sn-Glycerol-3-phosphate acyltransferase [G3PAT, PlsB (E.coli), EC 2.3.1.15] is an enzyme involved in glycerolipid biosynthesis, catalysing the acylation of glycerol-3-phosphate (G3P) to produce lysophosphatidic acid (LPA). Chilling tolerance in plants is

Palladium-Catalyzed Reductive Conversion of Acyl Fluorides via Ligand-Controlled Decarbonylation

open access: yes, 2018
Ligand-controlled non-decarbonylative and decarbonylative conversions of acyl fluorides were developed using a Pd­(OAc)2/Et3SiH combination. When tricyclohexylphosphine (PCy3) was used as the ligand, aldehydes were obtained as simple reductive conversion

LPCAT3 as a Potential Drug Target for Ultraviolet Radiation–Induced Cataract: Insights From Multiomics Analysis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Ultraviolet B (UVB) radiation is a major risk factor for cataract development, but the molecular mechanisms underlying this process, particularly the involvement of regulated cell death pathways such as ferroptosis, remain unclear. Transcriptomic, proteomic, and metabolomic analyses were performed on lens tissues from UVB‐induced cataract rat ...

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.
