Gold Nanoparticles–Dynamic Constitutional Frameworks as Adaptive Hybrid Conjugates for Enzyme Immobilization

ChemistryEurope, EarlyView.
Dynamic constitutional frameworks (DCFs) and gold nanoparticles (AuNps) assemble into larger and well‐distributed conjugates providing an efficient platform for biosensing and biocatalytic applications. Dynamic constitutional frameworks (DCFs), connecting monomers via reversible covalent bonds, can initiate the assembly of gold nanoparticles (AuNps ...

Synthetic Cathepsin B Sensitive Adjuvant‐Peptide Conjugates to Target Intracellular Toll‐Like Receptors 7 and 8

ChemistryEurope, EarlyView.
Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

Food Chemistry International, EarlyView.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...
