Synthesis, Characterization, and Biological Assessment of 2‐Methoxynicotinonitrile Derivatives

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
We report the synthesis of new 2‐methoxy‐3‐cyanopyridine derivatives via the nucleophilic aromatic substitution pathway, along with their crystal structure determination and preliminary biological evaluation. The new synthetic conversion described here demonstrates a practical method of preparing structurally diverse 2‐methoxy‐3‐cyanopyridines and ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, Volume 73, Issue 9, Page 1278-1290, September 2026.
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 CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Identification of New Anti‐Trypanosoma brucei Leads: An Integrated CRK12‐Guided Virtual Screen With Experimental Validation

Chemical Biology &Drug Design, Volume 108, Issue 3, September 2026.
An integrated computational‐experimental workflow enabled CRK12‐guided hit discovery against Trypanosoma brucei under limited structural and ligand data. The workflow of virtual screening and anti‐T. brucei bioassays identified 4 hit compounds, including three low‐micromolar leads (IC50 = 1.47, 0.81, and 1.33 μM). ABSTRACT Human African trypanosomiasis

Targeting Human Immunodeficiency Virus Integrase Beyond the Active Site: The Discovery and Development of Allosteric Integrase Inhibitors

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Human immunodeficiency virus (HIV) allosteric integrase inhibitors (ALLINIs) offer a vital alternative to standard therapies by targeting noncatalytic sites. By inducing aberrant integrase multimerization, they disrupt viral maturation. This review explores their medicinal chemistry evolution, detailing structural insights, structure–activity ...

Conservation of the Hydrogen-Bonded Pyridone Homosynthon in Halogen-Bonded Cocrystals

, 2022
Seven cocrystals of pyridone and perfluorinated halocarbons have been prepared. In all cases pairs of pyridone molecules are connected into dimers by two N–H···O hydrogen bonds, forming the characteristic pyridone homosynthon of R22(8) topology.
