  • Publication number: 20240043379
    Abstract: The invention relates to novel prodrugs or conjugates of the general formula (Ia) in which cytotoxic drugs, for example kinesin spindle protein inhibitors, are masked with legumain-cleavable groups and hence release the drug, and to the use of these prodrugs or conjugates for treatment and/or prevention of diseases, and to the use of these prodrugs or conjugates for production of medicaments for treatment and/or prevention of diseases, especially of hyperproliferative and/or angiogenic disorders, for example cancers.

    Inventors: Hans-Georg LERCHEN, Anne-Sophie REBSTOCK, Leo MARX, Sarah Anna Liesa JOHANNES, Beatrix STELTE-LUDWIG, Lisa DIETZ, Carsten TERJUNG, Christoph MAHLERT, Simone GREVEN, Anette SOMMER, Sandra BERNDT
  • Publication number: 20230381327
    Abstract: The present invention relates to compounds (reactive conjugates) for the chemical modification of therapeutic antibodies or proteins. The compounds enable the regioselective attachment of payloads to an antibody or antibody fragment in one single step, thereby producing a modified antibody or modified antibody fragment, which can be used for diagnosing, monitoring, imaging or treating disease.

  • Publication number: 20230039341
    Abstract: The present invention relates to novel binder-prodrug conjugates (APDCs) where binders are conjugated with inactive precursor compounds of kinesin spindle protein inhibitors, and to antibody-drug conjugates ADCs and to processes for producing these APDCs and ADCs.

  • Publication number: 20220062371
    Abstract: The present invention relates to ligand-drug-conjugates for the treatment of disease. In particular, the present invention relates to ligand-drug-conjugates comprising a linker system, which is selectively recognized and cleaved by the exopeptidase (i.e. carboxydipeptidase) activity of Cathepsin B, resulting in improved intracellular delivery of a drug to a target cell. The present invention also relates to ligand-drug-conjugates for the intracellular delivery of cytotoxic agents in tumor cells.

  • Publication number: 20190351066
    Abstract: The invention relates to novel prodrugs or conjugates of the general formula (Ia) in which La, n, R and D have the definitions given in the description and which have a structural motif reduced to an asparagine derivative as cleavage site for tumour-associated proteases such as legumain, in which cytotoxic drugs, for example kinesin spindle protein inhibitors, are released by legumain cleavage, and to the use of these prodrugs or conjugates for treatment and/or prevention of diseases, and to the use of these prodrugs or conjugates for production of medicaments for treatment and/or prevention of diseases, especially of hyperproliferative and/or angiogenic disorders, for example cancers. Reduction of the legumain-cleavable substrate peptide sequence to an asparagine derivative as structural motif, as a result of slowed legumain cleavage, achieves an increase in stability in the lysosomes of healthy organs while simultaneously maintaining the high anti-tumour effect.
