<p>An intracellular targeting bipodal-peptide binder specifically binding to an intracellular target molecule, comprising: (a) a structure-stabilizing region comprising a parallel amino acid strand, an antiparallel amino acid strand or parallel and antiparallel amino acid strands to induce interstrand non-covalent bonds; (b) target binding regions I and II each binding to each of both termini of the structure-stabilizing region, wherein the number of amino acid residues of the target binding region I is n and the number of amino acid residues of the target binding region II is m; and (c) a cell-penetrating peptide (CPP) linked to the structure-stabilizing region, the target binding region I or the target binding region II. Also contemplated is a method for preparing an intracellular targeting bipodal-peptide binder. The bipodal-peptide binder capable of binding to intracellular targets has applications to drugs, in vivo molecular imaging, in vitro cell imaging, drug delivery targeting and escort molecules.</p> |
