A new peptide synthesis using 2-fluoro-1,3,5-trinitrobenzene. Syntheses of thyrotropin releasing hormone and leucine-enkephalin [PDF]

, 1979
2-Fluoro-1,3,5-trinitrobenzene has been found to be a useful new condensing reagent for peptide synthesis. A variety of dipeptides have been prepared from the corresponding amino acids with the reagent.

Genotype‐Dependent Phenylpropanoid Pathway Specialization in Prunus avium Fruits and Leaves Revealed by Untargeted Metabolomics

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Phenylpropanoids are specialized metabolites involved in multiple aspects of plant physiology and contribute to fruit quality and human health benefits. In sweet cherry (Prunus avium L.), metabolomic studies have largely focused on fruits, showing that cultivar identity contributes to phenylpropanoid pathway specialization.

Probing the Influence of Sulfur–Aromatic Interactions on the Electronic Structure of Gas‐Phase Peptides

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...

Mapping the Substrate Specificity Landscape of PAD2 and PAD4 Enzymes

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein citrullination, driven by peptidyl arginine deiminases (PAD2, PAD4), is linked to multiple diseases. Using a combinatorial peptide library and advanced mass spectrometry, we reveal distinct substrate selectivity profiles of PAD2 and PAD4. While PAD2 broadly citrullinates arginine‐containing peptides, PAD4 is highly sequence‐restricted, with ...
