    摘要: The invention relates to bispecific and oligospecific, mono- and oligovalent receptors which are prepared by gene manipulation by fusion of DNA coding for F(ab) fragments of antibodies of two or more different specificities by means of suitable linkers. In this connection, one specificity is preferably directed either against an epitope, which is located on the cell membrane or in the interstitium, of a tumor-associated antigen (TAA) or against an epitope in the tumor endothelium (TE), while the other specificities relate to high-molecular or low-molecular weight ligands and react, for example, with the Komplexons ethylenediaminetetraacetate and diethylenetriaminepentaacetate in Y90 complexed form (EDTA-Y90 and DTPA-Y90 respectively). In a particularly preferred embodiment, the binding with the Komplexons takes place on the Komplexon receptor arm via fos-jun interaction (or else avidin-biotin interaction). Other preferred specificities have catalytic properties.

    摘要: Provided herein are carbohydrate complement-modified bifunctional glycoproteins, and their use in tumor-selective therapy. The bifunctional glycoproteins comprise a first component that specifically binds to a tumor-specific antigen and a second component having enzymatic activity by means of which a non-toxic prodrug is cleaved into a cytotoxic drug. The carbohydrate complement comprises at least one exposed carbohydrate residue selected from the group consisting of mannose, galactose, N-acetylglucosamine, N-acetyllactose, glucose and fucose. The modified carbohydrate complement contributes to increased relative concentration of the glycoproteins at the site of the tumor, and enhanced clearance from the general circulation and non-tumor sites.

    摘要: Antigenic constructs which result from linkage of major histocompatibility complex (MHC) class I antigens with specific carrier molecules are described. The linkage is effected N- or C-terminally by covalent bonding or, for example, in the case of non-covalent bonding by an avidin/biotin bridge. The specific carrier molecules bind selectively to target cells and are preferably monoclonal antibodies. Processes of genetic manipulation for the preparation of such constructs are indicated. Antigenic constructs according to the invention are used to damage or eliminate target cells.
