Iron-Catalyzed Formation of 2‑Aminopyridines from Diynes and Cyanamides [PDF]
, 2016 Diynes and cyanamides undergo an iron-catalyzed [2 + 2 + 2] cycloaddition to form highly substituted 2-aminopyridines in an atom-efficient manner that is both high yielding and regioselective. This system was also used to cyclize two terminal alkynes and

Rapid protium-deuterium exchange of 4-aminopyridines in neutral D2O under microwave irradiation [PDF]
, 2016 4-Aminopyridines undergo surprisingly rapid and highly-selective H/D exchange at C-2 and C-6 in neutral D2O upon microwave irradiation at only 190 °C for 2 h in a sealed vessel.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
Mass Spectrometry Reviews, EarlyView.ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

The aminolysis of p-nitrophenyl acetate by aminopyridines. Mechanisms in aqueous and aprotic solvents [PDF]
, 1980 In dimethyl sulfoxide, the aminolysis of p-nitrophenyl acetate by aminopyridines results in amide formation, through nucleophilic catalysis by the ring nitrogen for 4-aminopyridine, but by direct amino nitrogen attack for 2-aminopyridine (as previously ...

Movement Disorders in Developmental and Epileptic Encephalopathies
Movement Disorders Clinical Practice, EarlyView.Abstract Background Monogenic developmental and epileptic encephalopathies (DEE) frequently feature co‐occurring movement disorders. Gene discovery has expanded epilepsy‐dyskinesia syndromes (EDS) from classic associations such as stereotypies in Rett syndrome to PRRT2‐related infantile seizures with paroxysmal dyskinesia and crouched gait in SCN1A ...

Development of membrane conductance of chick skeletal muscle in culture. II. Effect of aminopyridines [PDF]
, 1980 The effects of 4-aminopyridine and 3,4-diaminopyridine on membrane parameters during differentiation of embryonic chick skeletal muscle in culture have been studied. Both agents caused depolarization of fibres at all stages of development.

Journal of Polymer Science, EarlyView.In this study, curing behavior of epoxy resins using a dual‐locked thermal latent curing agent (DCA) was analyzed using DSC and FT‐NIR. The DCA was successfully dissolved in the bisphenol A type epoxy resin (DGEBA). Furthermore, the prepared one‐component epoxy resin was used as an adhesive and achieved excellent adhesive strength (> 25 MPa).

The photoswitchable ABAMIs for the future regulation of GWT1 in a spatiotemporal level
Smart Molecules, EarlyView.The GWT1‐targeted azobenzene‐aminopyridine derivatives (ABAMIs), sensitive to the light at wavelengths from 365 to 520 nm, are separately developed as photochromic ligands to regulate bioactivity as well as the GWT1 functions. These molecules are smart tools in photopharmacological studies, giving an innovative method for understanding functional GWT1 ...
