The kinetics of the reduction of the lipophilic quinone avarone by n-alkyl-1,4-dihydronicotinamides of various lipophilicities

Journal of the Serbian Chemical Society, 1999
Several NADH model compounds, N-alkyl-1,4-dihydronicotinamides, some of them possessing amphiphilic properties, have been synthesized, and the kinetics of their reaction with a biologically active liphophilic quinone, avarone, has been studied in a ...

Acute Toxicity Testing of Pink Salmon (Oncorhynchus gorbuscha) with the Tire Rubber–Derived Chemical 6PPD-Quinone [PDF]

N‐(1,3‐dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine‐quinone (6PPD‐quinone) is a widespread contaminant of emerging concern resulting from oxidation of 6PPD, which is an antidegradant substance added to tires.

Toward Sustainable Smart Packaging: Demonstration of Laser‐Induced Graphene Sensors on Orange‐Based Substrates

Advanced Electronic Materials, EarlyView.
Orange peel waste is directly transformed into biodegradable bioplastic films and converted into electronically active laser‐induced graphene (LIG) sensors through single‐step 450 nm laser scribing. Without requiring conductive inks, metallic coatings, or transfer steps, localized photothermal conversion creates porous 3D graphitic networks with sheet ...

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Embedded Morgan Fingerprints for More Efficient Molecular Property Predictions With Machine Learning

Advanced Intelligent Discovery, EarlyView.
High dimensionality of Morgan fingerprints causes overfitting and slow training. Embedded Morgan Fingerprint (eMFP) compresses this encoding while keeping key structural information intact. Tested on five regression models across three databases for HOMO–LUMO gap prediction, eMFP outperforms standard fingerprints, training faster on large, high ...

Electrochemical Control of Scholl Reaction: Arenium Cation Versus Radical Cation Pathways

Angewandte Chemie, EarlyView.
Electrochemical control of Scholl reactions allows selective access to the arenium cation and radical cation pathways via low‐potential acidic (LPA) and high‐potential neutral (HPN) conditions, respectively. This control reveals that most substrates react through both pathways, albeit with clear preferences, and provides an experimental foundation for ...

SYNTHESIS AND CATECHOLASE ACTIVITY OF Cu(II) AND Fe(III) COMPLEXES OF 4-METHYL-2-((PIPERIDIN-1-YL)METHYL)PHENOL

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2020
This study is aimed at evaluating the impact of N- and S- bonding modes of thiocyanate substituent on catecholase activity as its presence in the coordination sphere of the metal complex can either reduce catecholase activity or otherwise. 4-Methyl-2-(
