Moreover, TRF possesses a special conformation in the membrane of phospholipid bilayer due to its unsaturated phytyl
Both tocopherols and tocotrienols (T3) belong to the family vitamin E, with each of them comprising four homologs ([alpha], [beta], [gamma], and [delta]); they differ structurally in that tocopherols contain a saturated phytyl
chain whereas tocotrienols possess an unsaturated isoprenoid side chain attached to 2-position on the chroman ring (Sen et al.

and methyl ester groups are substituted by sodium or potassium (SARKAR et al.
It is known that gamma-tocopherol inhibits human prostate cancer cell proliferation via down-regulation of cyclin-related signaling but tocopherol and tocotrienol metabolites with a shortened phytyl
chain, carboxyethyl hydroxychromans, were not previously investigated as anti-proliferative agents.
