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

Acta Crystallographica Section D, Volume 82, Issue 7, Page 836-844, July 2026.
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 ...

Anticancer α-, γ-, and δ-carboline derivatives: structures, mechanisms of action, and SARs

European Journal of Medicinal Chemistry Reports
Carboline consists of a pyridine ring fused with an indole skeleton, and it serves as a potential drug scaffold. Depending on the relative position of the pyridine N to the indole N, carbolines can be categorized into α-, β-, γ-, and δ-subfamilies.

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...
