Synthesis of Compounds of the Pyrimidine Series Based on the Reactions of 3-Arylmethylidenefuran-2(3H)-ones with N,N-Binucleophilic Reagents

Molecules, 2017
The arylmethylidene derivatives of furan-2(3H)-ones are important building blocks for the synthesis of various heterocyclic compounds containing pyrimidine and pyridazine structural fragments, analogues of nitrogen-containing bases of pyrimidine series ...

The NLRP3 Inflammasome: Mechanisms of Activation, Regulation, and Therapeutic Opportunities

MedComm, Volume 7, Issue 3, March 2026.
Diverse diseases converge on NLRP3. We depict a discovery‐to‐clinic track: high‐throughput/phenotypic screens, structure‐guided design, and modality innovation (allosteric inhibitors, interface blockers, degraders) deliver third‐generation, disease‐tailored NLRP3 control.

Carbon Nitride Thin‐Film Planar Heterojunctions for Photoelectrocatalytic C–N Coupling

Small Structures, Volume 7, Issue 3, March 2026.
Carbon nitride thin films have attracted increasing attention as active materials for energy conversion. Herein, it is shown how the presence of a conductive interlayer can substantially improve performance and photoelectrode stability in the photoelectrocatalytic oxidation of organic molecules and how the conductive interlayer influences product ...

New thiazol-pyridazine derivatives as antimicrobial and antiviral candidates: Synthesis, and application

Journal of Saudi Chemical Society
In this manuscript, we are motivated to investigate the reaction site-selectivity for the hydrazo thiazole derivatives (6a–c) with different types of active methylene groups such as malononitrile, and ethyl cyanoacetate.

Electrochemical and Spectroscopic Studies of Pyridazine Derivatives

Portugaliae Electrochimica Acta, 2004
This work reports on cyclic voltammetry and spectroscopic UV-Vis investigations of some pyridazine derivatives 1-8 in dimethylformamide. In the electrochemical study, monochlorinated pyridazines 2-8 exhibit two reductions but in the case of dichlorinated derivative 1 an additional wave is seen for the reduction of the second carbon-chloride bond.
