  • Patent number: 5563250
    Abstract: The present invention provides cleavable conjugates whose linkers contain a labile bond that is cleavable under a variety of mild conditions, including weakly acidic. Since the agent may be bonded directly to the linker, cleavage can result in release of native agent. The invention also provides methods for producing cleavable conjugates. Preferred agents include drugs, toxins, biological response modifiers, radiodiagnostic compounds, radiotherapeutic compounds, and derivatives thereof. The targeting molecule employed in the invention may be an intact molecule, a fragment thereof, or a functional equivalent thereof. In a particularly preferred embodiment, the targeting molecule is a monoclonal antibody directed towards a tumor-associated antigen in man. The invention further provides methods for delivering to the cytoplasm of a target cell an agent free of its targeting molecule carrier.

  • Patent number: 5549883
    Abstract: A chemically defined polymeric carrier comprising a series of .alpha.-amino acids in any combination containing side chains to which diagnostic/therapeutic and chelating agents can be covalently joined through cleavable linkers either directly or covalently joined through cleavable linkers after chemical modification of the side chains. Hydrazone, disulfide, and ester linkages in any combination can be present in the polymeric carrier between the side chains of the .alpha.-amino acids and the agents. The presence of a particular covalent linkage between the side chain and the agent in the carrier is determined by the functional group present in the side chain of the .alpha.-amino acid and the functional group present in the agent. The .alpha.-amino acids with side chains to which agents do not covalently join can function as spacers to minimize interaction between bulky molecules attached to the polymeric carrier. In addition, those .alpha.

  • Patent number: 5112954
    Abstract: The activity of cytotoxic agents on target cells is enhanced through administration of a sensitizing agent to a patient prior to or simultaneously with administration of the cytotoxic agent. One or both of the two types of agents are attached to antibodies specific for the desired target cells, thereby enhancing the cytotoxic effect on target cells compared to non-target cells. The sensitizer and/or the cytotoxic agent may be attached to monoclonal antibodies specific for cancer cells to selectively eradicate the cancer cells while minimizing toxicity toward normal tissues.
