Multifaceted role of tocotrienols in cardioprotection supports their structure: Function relation

Abstract

Tocotrienols are a class of vitamin E which modulates several mechanisms associated with cardioprotection, anti-cancer, anti-diabetic, and neuroprotection. Unlike other Vitamin E-like compounds, tocotrienols possess inimitable properties. Quite a lot of studies have determined the cardioprotective abilities of tocotrienols and have been shown to possess novel hypocholesterolemic effects together with an ability to reduce the atherogenic apolipoprotein and lipoprotein plasma levels. In addition, tocotrienol has been suggested to have an antioxidant, anti-thrombotic, and antitumor effect indicating that tocotrienol may serve as an effective agent in the prevention and/or treatment of cardiovascular disease and cancer. The bioactivity exhibited is due to the structural characteristics of tocotrienols.Rich sources of tocotrienolswhich include rice bran, palmoil, and other edible oils exhibit protective effect against cardiovascular disorders. The conclusions drawn fromthe early literature that vitamin E group of compounds provides an inevitable role in cardioprotection is sustained in many more recent studies. © Springer-Verlag 2011.
