The present invention relates to glycoconjugates of camptothecin derivatives in which at least one carbohydrate component is linked via suitable spacers with the 20-hydroxyl group of a camptothecin derivative. The invention furthermore relates to processes for preparing the compounds according to the invention and to their use as medicaments, in particular in connection with cancer.
Lectin-Mediated Drug Targeting: Discrimination of Carbohydrate-Mediated Cellular Uptake between Tumor and Liver Cells with Neoglycoconjugates Carrying Fucose Epitopes Regioselectively Modified in the 3-Position
The circumvention of efficient "carbohydrate traps" in the liver is required for targeting glycoconjugates on tumor cells. As shown in the model system of bovine serum albumin (BSA) conjugates, the nature of R(1)-R(3) of the fucose epitope plays an important role in the discrimination of cellular uptake between tumor and liver cells as well as in the cytotoxic activity.
