Publication number: 20080213352Abstract: Described herein are pharmaceutically acceptable compositions comprising fullerene molecules dispersed in vesicles comprising phosphatidylcholine (PC) phospholipid molecules and non-PC phospholipid molecules suspended in aqueous solution. In preferred embodiments, the phospholipid molecules are substantially uniformly organized into vesicles composed of one or more lipid bilayers and the fullerene molecules are substantially uniformly distributed within the lipid bilayers of the vesicles. Methods of forming these fullerene containing liposomes are also described. Such fullerene containing liposomes provide carriers for delivery of fullerenes for cosmetic, therapeutic, and imaging applications among other uses.Type: ApplicationFiled: March 3, 2008Publication date: September 4, 2008Applicant: Luna Innovations IncorporatedInventors: Robert P. Lenk, Alexandru Dragos Petru Papoiu, Darren MacFarland, Stephen R. Wilson

Publication number: 20080214514Abstract: Described herein are steroid derivatives of fullerene moieties, for example fullerene derivatives in which cholesterol, or a cholesterol moiety, is attached via ester, amide, or ether bonds to one of a variety of “linkers,” e.g., chemical groups including alkyl chains and aromatic groups, which are then connected to the fullerene moiety. The steroid moiety can confers useful solubility in components of biological fluids and/or pharmacologically acceptable carriers and can also affect the biodistribution of the fullerenes which makes the derivatives useful in imaging, diagnosis and the treatment or management of disease or complications of disease states.Type: ApplicationFiled: March 3, 2008Publication date: September 4, 2008Applicant: Luna Innovations IncorporatedInventors: Darren MacFarland, Jing Zhang, Zhiguo Zhou, Robert P.
