Interfacial oxidation of alpha-tocopherol and the surface properties of its oxidation products.

Journal of Lipid Research, 1978
dl-alpha-Tocopherol spread on an acidic subphase as a gaseous monolayer was oxidized slowly to a derivative that was identified by thin-layer chromatography as alpha-tocopherylquinone.

Beyond the Fixed Charge: A New On‐Tissue Derivatisation Strategy Employing Photoionisable Chromophores for Mass Spectrometry Imaging of Amino‐Containing Metabolites

Angewandte Chemie, EarlyView.
We introduce a novel chemical derivatisation strategy for the UV‐activated detection of elusive metabolites. Incorporation of a tocopherol‐active chromophore allows for the detection of tagged analytes as photoionised radical cations, selectively induced by a 266 nm laser.

Inverse modifications of heart and liver alpha-tocopherol status by various dietary n-6/n-3 polyunsaturated fatty acid ratios.

Journal of Lipid Research, 1990
The effect of dietary n-6/n-3 fatty acid ratio on alpha-tocopherol homeostasis was investigated in rats. Animals were fed diets containing fat (17% w/w) in which the n-6/n-3 ratio varied from 50 to 0.8.

The Antiproliferative Effect of Alpha Tocopherol in F98 Cell Culture

Proceedings, 2017
Alpha tocopherol is the most common and biologically active form of Vitamin E. The aim of this study was to evaulate the possible antiproliferative effect of alpha tocopherol on F-98 Glioblastoma cells. F-98 glioblastoma cell line was seeded at a density

A role of alpha-tocopherol and phylloquinone in the modulation of uterine contractility and reproductive function in mouse models

Medicina, 2017
Background and aim: Alpha-tocopherol has been implicated in reproduction processes, and deficiency of phylloquinone has been associated with serious complications in pregnancy.

PERANAN ISOZIM PROTEIN KINASE C-ΑLFA DALAM MEMEDIASI EFEK ANTIPROLIFERASI ALFA-TOKOFEROL PADA SEL STROMA PROSTAT

Jurnal Urologi Indonesia, 2016
Objective: Alpha tocopherol, other than its anti-oxidant activity, also has a non anti-oxidant activity that correlates with inhibition of PKC-alpha isozyme activity.

Lack of correlation between the alpha-tocopherol content of plasma and LDL, but high correlations for gamma-tocopherol and carotenoids

Journal of Lipid Research, 1996
In 59 healthy human subjects (37 male and 22 female) the concentrations of the lipid-soluble antioxidants alpha- and gamma-tocopherol, alpha- and beta-carotene, lycopene, cryptoxanthin, canthaxanthin, and lutein + zeaxanthin were determined in plasma ...

Effect of the Enrichment of Corn Oil With alpha- or gamma-Tocopherol on Its In Vitro Digestion Studied by ¹H NMR and SPME-GC/MS; Formation of Hydroperoxy-, Hydroxy-, Keto-Dienes and Keto-E-epoxy-E-Monoenes in the More alpha-Tocopherol Enriched Samples

Antioxidants, 2020
The aim of this study is the analysis of the in vitro digestion of corn oil, and of the effect of its enrichment with three levels of gamma- and alpha-tocopherol, by using, for the first time, 1H nuclear magnetic resonance (1H NMR) and a solid phase ...

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Glucose Deprivation‐Driven Concurrent Induction of Apoptosis/Disulfidptosis/Ferroptosis by Tumor Targeting Nanoassemblies in Triple‐Negative Breast Cancer Therapy

Advanced Functional Materials, EarlyView.
Innovative hybrid nanoassemblies installed with ferrocene, D‐α‐tocopherol succinate, and phloretin exploit the metabolic vulnerability of triple‐negative breast cancer under glucose starvation. By blocking glucose uptake, this single nanoplatform simultaneously orchestrates apoptosis, disulfidptosis, and ferroptosis to achieve synergistic and ...
