The Cellular and Organismal Effects of Nitroxides and Nitroxide-Containing Nanoparticles. [PDF]

Int J Mol Sci
Nitroxides are stable free radicals that have antioxidant properties. They react with many types of radicals, including alkyl and peroxyl radicals. They act as mimics of superoxide dismutase and stimulate the catalase activity of hemoproteins. In some situations, they may exhibit pro-oxidant activity, mainly due to the formation of oxoammonium cations ...

Nitroxides as Radiation Protectors [PDF]

Military Medicine, 2002
Selective protection of normal tissues from the damaging effects of ionizing radiation is an important objective in cancer treatment research. Likewise, radioprotective agents may be useful in protecting the human population in the event of radiation-related accidents or military conflicts.

Direct Iodination of Isoindolines and Isoindoline Nitroxides as Precursors to Functionalized Nitroxides [PDF]

European Journal of Organic Chemistry, 2013
AbstractA new method for the direct aryl iodination of isoindolines and isoindoline nitroxides that utilizes periodic acid and potassium iodide in sulfuric acid is presented. Di‐iodo functionalized tetramethyl and tetraethyl isoindolines and a di‐iodo tetramethyl isoindoline nitroxide were prepared in high yield (70–82 %).

Computation of nitroxide–nitroxide distances in spin‐labeled DNA duplexes [PDF]

Biopolymers, 2007
AbstractNanometer distances in nucleic acids can be measured by EPR using two 1‐oxyl‐2,2,5,5‐tetramethylpyrroline radicals, with each label attached via a methylene group to a phosphorothioate‐substituted backbone position as one of two phosphorothioate diastereomers (RP and SP).

Electrolyte–Framework Matching in High‐Voltage TEMPO‐COF Cathodes for Lithium Batteries

Advanced Science, EarlyView.
TEMPO‐functionalized covalent organic frameworks are investigated as high‐voltage cathodes for lithium batteries. Screening five electrolyte anions identifies lithium difluoro(oxalato)borate (LiDFOB) as the optimal electrolyte, balancing capacity, rate capability, and cycling stability, while buckypaper electrodes achieve high mass loading (40 mg cm−2)

PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...

Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

Chemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.
