The lipid bilayer, which comprises all cell membranes, represents a formidable barrier to the delivery of large hydrophilic molecules into cells. The ability to introduce information-rich molecules into cells is a challenge in the development of new therapeutics for diseases not currently amenable to small molecule intervention. This work focuses on the delivery of peptide-based molecules including; inhibitors, substrates and carriers into cells. A series of peptide-based inhibitors against caspase-3, an intracellular enzyme involved in apoptosis, were assessed for their cell membrane permeability. Proteolytic activation of a cell penetrating peptide was also investigated as a means of controlling the uptake of these carrier peptides into cells. Finally, the uptake and processing of an internally quenched Tat-caspase substrate was examined in cells undergoing apoptosis. This book may be of interest to scientists working in any area where large molecules need to be effectively...
