Effects of branching architecture and linker on the activity of hyperbranched polymer-drug conjugates.

Bioconjugate chemistry, 2009
Drug release from hyperbranched polymer-drug conjugates and the subsequent activity are influenced by the branching architecture and the linker. To gain an understanding of these effects, we used hyperbranched polyol and G4-OH polyamidoamine (PAMAM ...
