Thermally-targeted delivery of medicaments including doxorubicin

摘要

Elastin-like polypeptide (ELP) serves as a vector for thermally-targeted delivery of therapeutics, including cytotoxic chemotherapeutic drugs such as doxorubicin. Examples of an ELP-based delivery vehicle can comprise: (1) a cell penetrating peptide, such as a Tat peptide, (2) ELP, and (3) the lysosomally degradable glycylphenylalanylleucylglycine (GFLG) (SEQ ID NO: 3) spacer and a cysteine residue (SEQ ID NO: 4) conjugated to therapeutic such as doxorubicin, or an analog thereof.
