Interrelationships of alpha-tocopherol with plasma lipoproteins in African green monkeys: effects of dietary fats.

Journal of Lipid Research, 1993
The distributions of plasma lipoprotein alpha-tocopherol and lipids were studied in African green monkeys consuming diets enriched in saturated, monounsaturated, or polyunsaturated fatty acids.

alpha-Tocopherol enhances tumour growth inhibition by cis-dichlorodiammine platinum (II) [PDF]

Brazilian Journal of Medical and Biological Research, 2000
Present studies indicate that alpha-tocopherol enhances the efficacy of cisplatin as demonstrated by inoculation of Dalton's lymphoma cells incubated with either cisplatin (5 or 10 µg/ml) alone or cisplatin + alpha-tocopherol (25 or 50 µg/ml) into C3H/He

Effect of dietary supplementation with alpha-tocopherol on the oxidative modification of low density lipoprotein.

Journal of Lipid Research, 1992
Much data has accumulated supporting a proatherogenic role for oxidized low density lipoprotein (Ox-LDL). Micronutrient antioxidants such as alpha-tocopherol, the principal lipid-soluble antioxidant, assume potential significance because levels can be ...

Signalling functions of alpha-tocopherol in smooth muscle cells.

, 1997
alpha-Tocopherol but not beta-tocopherol, activates protein phosphatase 2A, decreases protein kinase C activity and attenuates smooth muscle cell proliferation at physiological concentrations.

Alpha-tocopherol is secreted from rat liver in very low density lipoproteins

Journal of Lipid Research, 1988
Three separate studies were carried out to test the hypothesis that rat liver secretes vitamin E (alpha-tocopherol) within very low density lipoproteins (VLDL).

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.

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.

Modular Access to α‐Tertiary Amines: Electrochemical Tandem Di‐Functionalization of Olefins With Ammonia Surrogates and Amino Acids

Angewandte Chemie, EarlyView.
A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

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.

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.
