Burton G, Joyce A, U Ingold K
Arch Biochem Biophys . 2022 Jun; 726:109230. PMID: 35660300
The concentrations of lipid-soluble, chain-breaking antioxidants in human plasma and in erythrocyte ghosts have been determined for the first time by an inhibited autoxidation method. The results are very similar...

Czochara R, Litwinienko G, Korth H, U Ingold K
Angew Chem Int Ed Engl . 2018 Mar; 57(29):9146-9149. PMID: 29578273
In 1923, Wieland and Wingler reported that in the molecular hydrogen producing reaction of hydrogen peroxide with formaldehyde in basic solution, free hydrogen atoms (H ) are not involved. They...

Haidasz E, Meng D, Amorati R, Baschieri A, U Ingold K, Valgimigli L, et al.
J Am Chem Soc . 2016 Mar; 138(16):5290-8. PMID: 27023326
Persistent dialkylnitroxides (e.g., 2,2,6,6-tetramethylpiperidin-1-oxyl, TEMPO) play a central role in the activity of hindered amine light stabilizers (HALS)-additives that inhibit the (photo)oxidative degradation of consumer and industrial products. The accepted...

J Am Chem Soc . 2014 Dec; 137(1):94-7. PMID: 25533605
Hydrogen atom transfer is central to many important radical chain sequences. We report here a method for determination of both the primary and secondary isotope effects for symmetrical substrates by...

Valgimigli L, Amorati R, Fumo M, DiLabio G, Pedulli G, U Ingold K, et al.
J Org Chem . 2008 Feb; 73(5):1830-41. PMID: 18260673
Hydroquinones (benzene-1,4-diols) are naturally occurring chain-breaking antioxidants, whose reactions with peroxyl radicals yield 1,4-semiquinone radicals. Unlike the 1,2-semiquinone radicals derived from catechols (benzene-1,2-diols), the 1,4-semiquinone radicals do not always trap...

DiLabio G, U Ingold K, Walton J
J Org Chem . 2007 Sep; 72(21):8095-8. PMID: 17850162
Spectroscopic data are consistent with computations that show that, in their most stable conformations, the peroxyl moiety is equatorial in cyclohexylperoxyl radicals and axial in oxa- and most polyoxacyclohexyl-2-peroxyl radicals.
