Stepwise Synthesis of Tetrabenzotriazaporphyrins (TBTAPs) and Their Open 2‐ and 3‐Ring Fragments

Chemistry – A European Journal, EarlyView.
Unexpected reaction pathways to porphyrin‐phthalocyanine hybrids are uncovered by the synthesis of “half‐macrocycle” fragments and subsequent macrocyclization. Rather than the expected 2:2 “ABBA” product, the 3:1 “ABBB” hybrid is isolated as the only macrocyclic product.

Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

Chemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

A Solid‐Phase Approach to Chiral C2‐Substituted Cyclen and DOTA‐Like Lanthanoid Ligands

Chemistry – A European Journal, EarlyView.
Chiral C2‐substituted cyclen derivatives have been designed and synthesized from chiral cyclic peptoids. Their conversion into the corresponding DOTA‐type ligands opens new avenues for the development of high‐relaxivity MRI contrast agents. ABSTRACT Magnetic resonance imaging (MRI) is a powerful diagnostic modality that relies on Gd+3‐based contrast ...

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

Chemistry – 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 ...
