  • Patent number: 7732617
    Abstract: Tocopherol derivatives having the general formula: wherein n is an integer of 6 to 13, R1 is hydrogen, a silyl ether or acetate, R2 is an optionally substituted nitrogen-containing heterocycle or a polycyclic nitrogen-containing heterocycle; and pharmaceutically acceptable salts thereof are provided. A method for synthesizing the compounds is also provided. The tocopherol derivatives are capable of inhibiting the primary enzyme responsible for the metabolism of the tocopherols and tocotrienols compounds of vitamin E, namely tocopherol-?-hydroxylase, and thus increase the amount and prolong the availability of these compounds in plasma and tissue.
