The synthesis, physico-chemical behavior, and in vitro intracellular degradation of new biodegradable graft, diblock or multiblock polymer carriers that were designed to deliver bioactive compounds by passive tumor targeting were investigated. In all three carrier systems, the single polymers were linked via biodegradable disulfide bonds forming the graft, diblock or multiblock polymers. Here, degradation of the polymers in model buffer solutions mimicking intracellular environment as well as after incubation with EL4 T-cell lymphoma cancer cells were investigated. In both cases, degradation resulted in polymer fragments of molecular weight below the renal threshold.
