Abstract: This patent discloses a substituted fullerenes, compositions comprising the same, and their use as antioxidants. The substituted fullerenes comprise a fullerene core (Cn) and at least one of: (i) from 1 to 6 (>CX1X2) groups bonded to the fullerene core; (ii) from 1 to 18 —X3 groups bonded to the fullerene core; (iii) from 1 to 6 —X4— groups bonded to the fullerene core; or (iv) from 1 to 6 dendrons bonded to the fullerene core.

Abstract: Compositions and methods for administering a therapeutic agent to a mammal are disclosed. The compositions comprise either (i) vesicles comprising an amphiphilic substituted fullerene, wherein the therapeutic agent is present in the vesicle interior or between layers of the vesicle wall, (ii) a substituted fullerene, comprising a fullerene core and a functional moiety, wherein the therapeutic agent is associated with the substituted fullerene, or (iii) carbon nanotubes, wherein the therapeutic agent is covalently bonded to the carbon nanotubes.

Abstract: The invention is directed to multiply-substituted fullerene derivatives of novel configurations, and methods for their preparation and use. The methods involve the combinatorial synthesis of a library of fullerene derivatives and comprises the steps of forming a mixture of fullerene derivatives by reacting the Cn fullerene with two or more reactive precursor compounds, and removing the unreacted compounds to yield the fullerene derivatives having the desired activity. Methods for the identification and screening of a combinatorial library of fullerenes by 3He-nuclear magnetic resonance and electrospray mass spectrometry to define members with the optimal desired activity are also provided.
