Modes of Uptake of Benzylamine by the Ehrlich Cell

open access: yesJournal of Biological Chemistry, 1966
Abstract The Ehrlich ascites tumor cell shows three modes of uptake of 14C-benzylamine: an instantaneous binding, quickly reversed by washing the cell; a rapid, saturable uptake process; and a slower, apparently nonsaturable uptake process. Both the latter appear to involve predominantly if not exclusively the neutral, unprotonated form of the amine ...

A Stable Isopterin Mimic of a Potent Bacterial Stimulant of T Cells

open access: yesChemistry – A European Journal, EarlyView.
A microbial metabolite covalently binds immunological protein MR1 to potently activate specific lymphocytes called MAIT cells, but it is too unstable for biological applications. Here, using synthesis, assays, protein crystallography, and computer modelling, we report a water‐stable analogue that activates reporter cells expressing the MAIT T cell ...

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Strain‐Release Pentafluorosulfanylation of Carbonyl‐Containing Disubstituted Bicyclobutanes: A Fortuitous Path to SF5‐Containing Oxa[2.1.1]bicyclohexanes

open access: yesAngewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class

Multidimensional Engineering Enabling Rate‐Matched C−N Coupling for Efficient Organonitrogen Electrosynthesis

open access: yesEcoEnergy, EarlyView.
This review introduces rate matching as a unifying design principle for efficient electrochemical C−N coupling and highlights multidimensional engineering of catalysts, interfaces, and reactors to synchronize the generation of carbon‐ and nitrogen‐containing intermediates, balance their surface coverages, maximize C−N bond formation, and enable ...

Direct Conversion of Aryl Iodides Into Benzylamines by Aminomethylation: Reaction Scope, Mechanistic Studies, and Applications

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This study presents an efficient aminomethylation of aryl iodides with formamides for the synthesis of benzylamines using a reusable palladium catalyst at a loading of 65 mol ppm. The substrate scope is systematically evaluated, and mechanistic investigations provide insight into the reaction pathway and the origin of the observed catalytic efficiency.

Stereodivergent Synthesis of C5‐α‐Substituted Linezolid Derivatives From D‐Mannitol and Structure–Antibacterial Activity Evaluation

open access: yesChirality, Volume 38, Issue 9, September 2026.
A stereodivergent route from D‐mannitol enables access to enantiopure C5‐α‐substituted linezolid analogues with full configurational control. Biological evaluation reveals that α‐substitution abolishes antibacterial activity irrespective of stereochemistry, establishing a strict steric limitation at C5 and highlighting the dominant role of substituent ...
