Metabolic stability of superoxide adducts derived from newly developed cyclic nitrone spin traps [PDF]

open access: yes, 2014
Reactive oxygen species are by-products of aerobic metabolism involved in the onset and evolution of various pathological conditions. Among them, the superoxide radical is of special interest as the origin of several damaging species such as H2O2 ...

Thermally Activated Paramagnets from Diamagnetic Polymers of Biphenyl-3,5-diyl Bis(tert-butyl Nitroxides) Carrying Methyl and Fluoro Groups at the 2’- and 5’-Positions

open access: yesCrystals, 2016
Three new biradicals—2’,5’-dimethyl-, 2’-fluoro-5’-methyl-, and 5’-fluoro-2’-methyl- biphenyl-3,5-diyl bis(tert-butyl nitroxides)—were synthesized. The magnetic susceptibility measurements revealed their diamagnetism below and around room temperature ...

Stereoselective Aminoxylation of Biradical Titanium Enolates with TEMPO [PDF]

open access: yesChemistry – A European Journal, 2014
AbstractA highly efficient and straightforward aminoxylation of titanium(IV) enolates from (S)‐N‐acyl‐4‐benzyl‐5,5‐dimethyl‐1,3‐oxazolidin‐2‐ones with TEMPO has been developed. A wide array of functional groups on the acyl moiety, including alkyl and aryl substituents, olefins, esters, or α‐cyclopropyl, as well as α‐trifluoromethyl groups, are well ...

A structural model for the full-length blue light-sensing protein YtvA from Bacillus subtilis, based on EPR spectroscopy [PDF]

open access: yes, 2013
A model for the full-length structure of the blue light-sensing protein YtvA from Bacillus subtilis has been determined by EPR spectroscopy, performed on spin labels selectively inserted at amino acid positions 54, 80, 117 and 179. Our data indicate that
