Patent ID: 8841414

Claim:
A compound for delivery to a target site, comprising: (a) a cell penetrating peptide (CPP), wherein the CPP is selected from the group consisting of: SynB1, SynB1-NLS, poly-arginine, VP22, MAP, hCT-derived CPP, MPG, Buforin 2, PEP-1, and Magainin 2, (b) an elastin-like polypeptide (ELP), wherein the ELP comprises the sequence (VPGXG) n (SEQ ID NO: 44) or (VPGXG) n WP (SEQ ID NO: 45), where n is an integer from about 30 to about 350 and each X is independently selected from valine (Val; V), glycine (Gly; G), and alanine (Ala; A) such that the selected Xs are Val:Gly:Ala in a 3:1:1 ratio or in a 1:7:8 ratio, and (c) a therapeutic peptide (TP).
