The invention is claimed as follows: 1. A composition comprising a single molecule that is capable of inhibiting a reactive oxygen species and a reactive carbonyl species, the single molecule comprising an antioxidant moiety, a carbonyl trapping moiety and a linker moiety that joins the antioxidant
The invention is claimed as follows: 1. A composition comprising a single molecule that is capable of inhibiting a reactive oxygen species and a reactive carbonyl species, the single molecule comprising an antioxidant moiety, a carbonyl trapping moiety and a linker moiety that joins the antioxidant moiety and the carbonyl trapping moiety, wherein the antioxidant moiety is selected from the group consisting of vitamin E, cinnamic acid derivatives, pyridoxamine, flavonoids, lipoic acid, antioxidants including natural antioxidants and synthetic antioxidants, derivatives thereof, and combinations thereof, wherein the carbonyl trapping moiety is selected from the group consisting of an aminooxy group, a 1,2-aminothiol group including a cysteine group, a penicillamine group, derivatives thereof, and combinations thereof and wherein the linker moiety is selected from the group consisting of piperazine, poly(ethylene glycol), lysine, an organic moiety containing a positive charge, an organic moiety containing a negative charge, an organic moiety containing a positive charge and a negative charge, derivatives thereof, and combinations thereof. 2. A composition comprising a single molecule that is capable of inhibiting a reactive oxygen species and a reactive carbonyl species, wherein the single molecule includes a vitamin E derivative selected from the group consisting of 2-(6-hydroxy-2,5,7,8-tetramethylchroman-2-yl)-1-(aminooxy)ethane; N-[2-(6-hydroxy-2,5,7,8-tetramethylchroman-2-yl)ethyl]-N'-(aminooxyacetyl)-piperazine; N-[2-(6-hydroxy-tetramethylchroman-2-yl)ethyl]-N'-(cysteinyl)-piperazine; N-[2-(6-hydroxy-tetramethylchroman-2-yl)ethyl]-N'-(penicillamyl)-piperazine, derivatives thereof, and combinations thereof. 3. A dialysis solution comprising a therapeutically effective amount of a composition capable of inhibiting a reactive oxygen species and a reactive carbonyl species, the composition comprising a single molecule comprising an antioxidant moiety, a carbonyl trapping moiety, and a linker moiety that joins the antioxidant moiety and the carbonyl trapping moiety, wherein the antioxidant moiety is selected from the group consisting of vitamin E, cinnamic acid derivatives, pyridoxamine, flavonoids, lipoic acid, antioxidants including natural antioxidants and synthetic antioxidants, derivatives thereof, and combinations thereof, wherein the carbonyl trapping moiety is selected from the group consisting of an aminooxy group, a 1,2-aminothiol group including a cysteine group, a penicillamine group, derivatives thereof, and combinations thereof and wherein the linker moiety is selected from the group consisting of piperazine, poly(ethylene glycol), lysine, an organic moiety containing a positive charge, an organic moiety containing a negative charge, an organic moiety containing a positive charge and a negative charge, derivatives thereof, and combinations thereof. 4. A two part peritoneal dialysis solution comprising: a first part including an osmotic agent; and a second part including a buffer, wherein the first part and the second part are admixed prior to use, and wherein at least one of the first part and the second part includes a therapeutically effective amount of a composition capable of inhibiting a reactive carbonyl species and a reactive oxygen species, the composition comprising a single molecule comprising an antioxidant moiety, a carbonyl trapping moiety, and a linker moiety that joins the antioxidant moiety and the carbonyl trapping moiety, wherein the antioxidant moiety is selected from the group consisting of vitamin E, cinnamic acid derivatives, pyridoxamine, flavonoids, lipoic acid, antioxidants including natural antioxidants and synthetic antioxidants, derivatives thereof, and combinations thereof, wherein the carbonyl trapping moiety is selected from the group consisting of an aminooxy group, a 1,2-aminothiol group including a cysteine group, a penicillamine group, derivatives thereof, and combinations thereof and wherein the linker moiety is selected from the group consisting of piperazine, poly(ethylene glycol), lysine, an organic moiety containing a positive charge, an organic moiety containing a negative charge, an organic moiety containing a positive charge and a negative charge, derivatives thereof, and combinations thereof. 5.
