We report on the thiol-ene chemistry guided preparation of novel thiolated polymeric nanocomposite films of abundant anionic carboxylic groups for electrostatic enrichment and sensitive electroanalysis of cationic dopamine (DA) in neutral solution. Briefly, the thiol-ene nucleophilic reaction of a carboxylated thiol with oxidized polypyrrole (PPy), which was electrosynthesized on an Au electrod...

Thiolated polymers are widely used in hydrogels for drug delivery, tissue engineering, and biofabrication. The oxidation of thiols is spontaneous, resulting the formation disulfide bridges cross-linking polymers. process is, however, difficult to control initiated directly when thiolated components exposed ambient conditions, which significantly complicates handling materials. Here, we show a f...

Thiol-ene and thiol-yne photomediated conjugations have received substantial attention in research practice. Herein is presented the photodisulfidation of alkenes based on radical-mediated 1:1 reaction a disulfide vinyl ether, which provides an additional route for formation types sulfides seen thiol-ene polymers. Although similar linkages are formed, this approach starting with disulfides expe...

Protein disulfide isomerase (PDI), ERp5, and ERp57, among perhaps other thiol isomerases, are important for the initiation of thrombus formation. Using the laser injury thrombosis model in mice to induce in vivo arterial thrombus formation, it was shown that thrombus formation is associated with PDI secretion by platelets, that inhibition of PDI blocked platelet thrombus formation and fibrin ge...

Maleimide-functionalised Pt(IV) complexes with highly selective binding properties to thiol groups were synthesised as precursors for binding of thiol-containing tumour-targeting molecules like human serum albumin.

In the presence of MnCl2 and a thiol (glutathione, cysteine, 2-nitro-5-thiobenzoic acid) horse radish peroxidase oxidizes p-hydroquinone to p-benzoquinone which in turn immediately adds the thiol present yielding 2-S-substituted p-hydroquinone.

Objective: Lung cancer has a poor prognosis. Thiol groups with high antioxidant capacity are converted to disulfide bonds through biochemical reactions that neutralize different oxidant compounds. The thiol-disulfide (SH-SS) homeostasis significant effects on cell mechanisms, transcription, and apoptosis. Here we present the prognostic role of dynamic SH-SS in patients operated for NSCLC. Mater...

Nanoparticle-polymer composites are important functional materials but structural control of their assembly is challenging. Owing to its crystalline internal structure and tunable nanoscale morphology, cellulose promising polymer scaffold for templating such composite materials. Here, we show bottom-up synthesis reducing end thiol-modified chains by iterative bi-enzymatic ?-1,4-glycosylation 1-...

Objective: The objectives of the present work were to carry out thiol-modification (i.e., thiolation) fenugreek polysaccharide (FP) and assess synthesized thiolated product (TFP) as a mucoadhesive excipient in designing formulations (metronidazole gels metronidazole buccal discs). Methods: Extracted CG was thiol-modified via an esterification reaction by utilizing thioglycolic acid with acidic ...
