Inactivation of tyrosinase photoinduced by pterin
Biochemical and Biophysical Research Communications, 2012 Tyrosinase catalyzes in mammals the first and rate-limiting step in the biosynthesis of the melanin, the main pigment of the skin. Pterins, heterocyclic compounds able to photoinduce oxidation of DNA and its components, accumulate in the skin of patients suffering from vitiligo, a chronic depigmentation disorder in which the protection against UV ...

Molecular Ecology, Volume 34, Issue 19, October 2025.ABSTRACT Colouration and patterning have been implicated in lineage diversification across various taxa, as colour traits are heavily influenced by sexual and natural selection. Investigating the biochemical and genomic foundations of these traits therefore provides deeper insights into the interplay between genetics, ecology and social interactions in

InorganicsThe synthesis of [Cu(PteN˄N)(P˄P)][BF4] complexes with pterin-fused phenanthroline (PteN˄N) derivatives and bisphosphine (P˄P) co-ligands was achieved through a mechanochemical approach. Due to the extremely poor solubility of PteN˄N ligands, traditional

Advanced Healthcare Materials, Volume 14, Issue 24, September 18, 2025.This study presents alkylated nitrobenzoselenadiazole (NBSD) photosensitizers that self‐assemble into programmable aggregates, enabling photo‐triggered pyroptosis and enhanced ROS generation. The lead compound, NBSD‐NOc, exhibits superior photodynamic activity, high cellular uptake, and implantable gel compatibility with pH‐responsive release.

Biosynthesis of Pteridines in Insects: A Review
InsectsPteridines are important cofactors for many biological functions of all living organisms, and they were first discovered as pigments of insects, mainly in butterfly wings and the eye and body colors of insects. Most of the information on their structures
