A method for treating inflammation or cancer sensitive to the compounds below in a recipient in need thereof, comprising administering a pyrazine derivative of formula I or II to the recipient in an amount effective to exhibit an antioxidant effect in the recipient, wherein formula I has the following structures:
- wherein B is a radical selected from the group consisting of X, X-SO3H, X-PO4 and X-alkyl═O in which X is an element selected from the group consisting of O, S, Se and Te;
- and R1 is H, R2 is selected from the group consisting of methyl, phenyl, p-hydroxybenzyl, and benzyl, R3 is p-hydroxyphenyl or p-methoxyphenyl and R4 is benzyl and substituted radicals of the foregoing.
A cosmetic composition comprising a base cosmetic and, in an amount effective to exhibit an antioxidant effect in a recipient, a pyrazine derivative of formula:
- wherein B is a radical selected from the group consisting of X, X-SO3H, X-PO4 and X-alkyl═O in which X is an element selected from the group consisting of O, S, Se and Te;
- and R1 is H, R2 is selected from the group consisting of methyl, phenyl, p-hydroxybenzyl, and benzyl, R3 is p-hydroxyphenyl or p-methoxyphenyl and R4 is benzyl and substituted radicals of the foregoing.
A food composition comprising a base food and, in an amount effective to exhibit an antioxidant effect in a recipient, a pyrazine derivative of formula:
- wherein B is a radical selected from the group consisting of X, X-SO3H, X-PO4 and X-alkyl═O in which X is an element selected from the group consisting of O, S, Se and Te;
- and R1 is H, R2 is selected from the group consisting of methyl, phenyl, p-hydroxybenzyl, and benzyl, R3 is p-hydroxyphenyl or p-methoxyphenyl and R4 is benzyl and substituted radicals of the foregoing.
