Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.
