Study Notes
pH Controlled Drug Release
- Therapeutic effects are achieved when drugs are released intracellularly in lysosomes or tumor tissue
- These areas are slightly acidic in comparison to healthy tissues
Advantages of Polymeric Prodrugs
- Less likely to be taken up by the liver
Lectins
- Sugar specific receptors present on the plasma membrane
- Primarily characterized on hepatocytes
Fas and Fas Ligand (Fas L)
- Present on both cancer and immune cells
- Interaction triggers a cascade of signals resulting in apoptosis
Poly(L-γ-glutamyl-glutamine) (PGG)
- Glutamic acid added to each glutamic acid in the polymer backbone
- Low immunogenicity
- Satisfactory solubility in aqueous and several organic solvents
- These qualities led to a range of applications in cancer drug delivery
