Formazans and their metal complexes

, 2006
The current data on the structure of formazans in crystals and in solutions are considered and some problems of tautomeric and conformational equilibria are discussed. Some novel classes of formazans synthesised over the past decade are presented.

Gas-phase oxidation and reduction of some 1-(2-benzothiazolyl)-3,5-diphenyl formazans. Complex formation with transition metals under laser desorption ionization [PDF]

, 1999
Five differently substituted 1-(2-benzothiazolyl)-3,5-diphenyl formazans were studied by laser desorption ionization (LDI) and matrix assisted laser desorption/ionization (MALDI) mass spectrometry. The best explanation of the results is that the formazan

Synthesis, Characterization and Anti-hyperglycemic Activity of some novel Formazans Derivatives [PDF]

, 2015
In the present investigation, a series of novel formazans 4[a – h]were synthesized by the condensation of Schiff bases2[a-c] and diazonium salt chloride of various substituted aromatic amines 3[a-c] .

Formazan as a Noninnocent Ligand: Catalytic Activity of [Ni(3-cyano-1,5-mesitylformazanate)((2-mercaptopyridinate)-κN,S)] in Electrochemical Hydrogen Production

Electrochem
Formazanates are the mono-deprotonated form of formazans, which exhibit a notable property of noninnocent behavior. Here, a new nickel–formazanate complex, [Ni(3-cyano-1,5-mesitylformazanate)((2-mercaptopyridinate)-κN,S)], was synthesized and ...

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

The stretching frequency of the Azo-group in Formazans

, 1956
Infra-red spectra between 680 and 1600 cm-1 are recorded for 10 formazans and five copper complexes derived therefrom. A common feature at c. 1450 cm-1 in the formazans is removed by chelation ; it is therefore suggested that 1450 cm-l is the stretching ...

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

Advanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Nanoporous Silica Embedded in Nanoporous Platinum: A Versatile Composite Coating for Implant‐Associated Drug Delivery From Neuronal Electrodes

Advanced Materials Technologies, EarlyView.
Nanoporous silica nanoparticles incorporated in nanoporous platinum offer the possibility for implant‐associated drug delivery from neuronal electrodes. ABSTRACT Sensorineural hearing loss, resulting from damage to the hair cells of the inner ear, profoundly impairs quality of life.
