Descripción general

Tocotrienols belong to the vitamin E family and have an unsaturated isoprenoid side chain. The various isoforms of tocotrienols differ in their methyl substitution in the chromanol head. α-Tocotrienol present in crude palm oil is regarded as a natural supplement.

Acciones bioquímicas o fisiológicas

α-Tocotrienol is an effective free radical scavengerand elicits protective functionality during oxidative stress in microsomes. It is a strong antioxidant, which reduces inflammation and is used in cancer treatment. α-tocotrienol supplementation may reduce cholesterol levels in hypercholesterolemia. α-tocotrienol is neuroprotective as it blocks glutamate-induced cell death in neuronal cells.
α-Tocotrienol may be used along with other isoforms to differentiate tocotrienol activities.
Tocotrienols are widely utilized for their strong antioxidant properties. The various isoforms of tocotrienols differ in their methyl substitution in the chromanol head. α-tocotrienol demonstrates neuroprotective properties by blocking glutamate-induced cell death in neuronal cells.

α-Tocotrienol (TCT) represents the most potent neuroprotective form of natural vitamin E that is Generally Recognized As Safe certified by the U.S. Food and Drug Administration. This work addresses a novel molecular mechanism by which α-TCT may be protective against

Vitamin E, an essential nutrient with powerful antioxidant activity, is the mixture of two classes of compounds, tocopherols (TPs) and tocotrienols (TTs). Although TTs exhibit better bone protective activity than α-TP, the underlying mechanism is poorly understood. In this study

The natural vitamin E tocotrienols possess properties not shared by tocopherols. Nanomolar alpha-tocotrienol, not alpha-tocopherol, is potently neuroprotective. On a concentration basis, this finding represents the most potent of all biological functions exhibited by any natural vitamin E molecule. We

Release of mitochondrial proteins such as cytochrome c, AIF, Smac/Diablo etc., plays a crucial role in apoptosis induction. A redox-silent analog of vitamin E, alpha-tocopheryl succinate (alpha-TOS), was shown to stimulate cytochrome c release via production of reactive oxygen species
