Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Synthesis of Zwitterionic Tris(pyrazolyl) Ligands and Their Mn(II) Bis‐Chelates Exhibiting Charge–Transfer‐Induced Spin Crossover

European Journal of Inorganic Chemistry, Volume 29, Issue 28, 1 October 2026.
In this article, a series of zwitterionic scorpionate ligands based on the anionic tris‐(pyrazolyl)borate ligand scaffold is presented. These ligands are used to prepare bis‐chelates with divalent manganese ions. The resulting complexes are studied via magnetic, crystallographic, and electrochemical means to characterize the charge–transfer‐induced ...

Novel Pyrazole‐4‐Carbaldehyde Derivatives Having Potent COX‐2 Inhibition and Anti‐Tubercular Activity: Microwave‐Assisted Green Synthesis and Molecular Docking

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
ABSTRACT A series of 1‐(4‐Chorophenyl)‐3Aryl‐1‐H‐pyrazole‐4‐carbaldehyde derivatives were synthesized under the microwave irradiation (MW) technique. IR, 1H‐NMR, 13C‐NMR, and mass spectroscopic techniques were used to confirm the structure of the synthesized compounds.

Biological Evaluation, Molecular Docking, MD Simulation Study and Synthesis of (Z)‐N’‐(3‐phenoxybenzylidene)‐2‐(substituted‐amino aryl) Acetohydrazid

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Synthesis and biological evaluation (antibacterial, antifungal, anti‐tuberculosis, antiprotozoal) and in silico molecular docking of biphenyl ether based Schiff's base analogues. ABSTRACT In order to investigate their possible biological activity, a number of new Schiff base compounds based on diaryl ether, specifically 2‐(substituted‐arylamino)‐N′‐(3 ...

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...
