Structural basis of regioselective double halogenation of the β‐carboline tryptoline by the single‐component halogenase AetF

open access: yesActa Crystallographica Section D, EarlyView.
A structure of the flavin‐dependent single‐component tryptophan halogenase AetF bound to the non‐native tricyclic substrate tryptoline reveals a binding pose analogous to l‐tryptophan that directs C6‐first halogenation. Product analysis identifies 6,8‐dibromotryptoline as the final product.Flavin‐dependent halogenases (FDHs) offer a biocatalytic route ...

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Enzyme–MOF Composites: Quantitative Benchmarking and Evaluation of Biocatalyst Performance

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Rigorous evaluation of enzyme@MOF composites requires quantitative benchmarking. This study illustrates this approach by applying and comparing enzyme‐loading and activity‐assessment strategies for two structurally and functionally distinct enzymes, phenolic acid decarboxylase, and cytochrome c.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Practical Enantioselective Approach to 3‐Amino‐2‐Hydroxy Acids and Application to the Synthesis of Natural Products

open access: yesChirality, Volume 38, Issue 7, July 2026.
A practical and straightforward approach to optically active erythro 3‐amino‐2‐hydroxy acids and its application to the enantioselective synthesis of 3‐phenylisoserine and of the marine natural product 3‐amino‐2‐hydroxy‐6‐methylheptanoic acid is reported.

Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition

open access: yesChemistry–Methods, Volume 6, Issue 7, July 2026.
We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

Integrated Reaction Monitoring and In Situ Structural Elucidation of Reactive Intermediates With Time‐Resolved NOAH NMR Supersequences

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 7, Page 621-628, July 2026.
TR‐NOAH‐NUS enables real‐time reaction monitoring and direct structural characterization of transient intermediates. Integration of NOAH supersequences with t0‐filling minimizes reaction monitoring deadtime and provides high temporal resolution for kinetic analysis.
