Deracemization is like magic. Chiral catalysts and visible light act like a magician and his magic props, leading to deracemization as a magical tool that can convert a racemic compound into one of its enantiomers with 100 % atomic efficie...

Front Cover: Unveiling Photodegradation and Photosensitization Mechanisms of Unconjugated Pterins (Chem. Eur. J. 29/2023)
Von Wiley-VCH zur Verfügung gestellt
Pterins can be considered as biological jacks-of-all-trades. Firstly identified as pigments in butterfly wings, they are nowadays well-known cofactors in the synthesis of NO, nucleotides, and amino acids, markers in cell-mediated immune responses. Yet, not all of their properties are beneficial. Some of these pterins contribute to the photochemical evolution of vitiligo, a depigmentation disorder. Enhanced oxidative stress and cytotoxicity lead to melanocyte destruction and tissue damage. More information can be found in the Research Article by E. M. Arpa and I. Corral (DOI: 10.1002/chem.202300519).
