Interferon-antibody fusion proteins demonstrating potent apoptotic and anti-tumor activities

摘要

This invention provides novel chimeric moieties that show significant efficacy against cancers. In certain embodiments the chimeric moieties comprise a targeting moiety attached to an interferon. In certain embodiments, the chimeric moieties comprise fusion proteins where an antibody that specifically binds to a cancer marker is fused to interferon alpha (IFN-α).

主权项

1. A method of inhibiting growth and/or proliferation of a cancer cell, said method comprising contacting said cancer cell with a chimeric construct comprising a type I interferon attached to a full-length antibody that binds to a tumor-associated antigen, wherein said antibody is attached to said interferon by a peptide linker that is resistant to proteolysis, wherein the amino acid sequence of said peptide linker is SGGGGS (SEQ ID NO:62) or AEAAAKEAAAKAGS (SEQ ID NO:63).
