Abstract

A suitable carrier for camptothecin to act as therapy against the hepatitis C virus is presented. The carrier relies on an amphiphilic hybrid dendritic-linear-dendritic block copolymer, derived from pluronic F127 and bis-MPA dendrons, that forms micelles in aqueous solution. The dendrons admit the incorporation of multiple photoreactive groups that allow the clean and effective preparation of covalently cross-linked polymeric micelles (CLPM), susceptible of loading hydrophilic and lipophilic molecules. Cell-uptake experiments using a newly designed fluorophore, derived from rhodamine B, demonstrate that the carrier favors the accumulation of its cargo within the cell. Furthermore, loaded with camptothecin, it is efficient in fighting against the hepatitis C virus while shows lower cytotoxicity than the free drug.

Keywords: anti-HCV; camptothecin; cross-linked micelles; dendrimers; pluronic.
