Click FBP - Click Peptides

Cell penetrating peptides (CPPs) provide a delivery method for molecules across the membrane in an efficient manner without compromising the cell. FBP forms a sheet structure when interacting with a membrane forming a transmembranous pore. FBP, also known as Pβ, is rapidly internalised and localises primarily to the nucleus. FBP is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-FBP allows a wide variety of applications particularly for conjugation, modification, and peptide design.
