An overview of synthesis and biological activities of 2-pyridone derivatives over the last decade
Discover Applied Sciences2-Pyridone frameworks are a pervasive member of the N-heterocyclic family of both chemical and therapeutic interest. 2-Pyridones and their bridged analogues have wide occurrences in nature and the presence of both aromatic and amide groups in the ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications
Journal of the Chinese Chemical Society, EarlyView.This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Ultrafast Decay Dynamics of the 21ππ* Electronic State of N‑Methyl-2-pyridone
The ultrafast decay dynamics of N-methyl-2-pyridone upon excitation in the near-ultraviolet range of 261.5–227.9 nm is investigated using the femtosecond time-resolved photoelectron spectroscopy method.

The FEBS Journal, Volume 293, Issue 12, Page 3601-3620, June 2026.Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

Biological evaluation of pyridone alkaloids on the endocannabinoid system [PDF]
, 2017 Naturally occurring pyridone alkaloids as well as synthetic derivatives were previously shown to induce neurite outgrowth. However, the molecular basis for this biological effect remains poorly understood.

Advanced Science, Volume 13, Issue 29, 22 May 2026.This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.
