Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

Identification of Key Active‐Site Positions Controlling the Chemoselectivity of Aspergillus Brasiliensis Unspecific Peroxygenase

ChemBioChem, Volume 26, Issue 10, May 27, 2025.
Unspecific peroxygenase (UPO) from Aspergillus brasiliensis AbrUPO catalyzes the aromatic hydroxylation of substituted benzenes. By integrating structural elements from well‐characterized UPOs in AbrUPO variants, position 186 was identified as a critical determinant of enzyme chemoselectivity.

Tyrosinase Inhibition and Antimelanogenic Effects of Resorcinol‐Containing Compounds

ChemMedChem, Volume 19, Issue 23, December 2, 2024.
Resorcinol‐based compounds stand out as key inhibitors of tyrosinases (TYR) owing to their phenolic group's interaction with the dicopper centre and their ability to resist TYR‐mediated oxidation. While some well‐known examples are employed in dermatocosmetics and skin‐whitening products, this review covers the broader diversity of scaffolds, including
