  • Patent number: 11325888
    Abstract: The present invention relates to a method for the synthesis of compounds useful in the preparation of antibody drug conjugates (ADC), namely, monoprotected dimeric bifunctional prodrugs based on duocarmycin analogs. In a further aspect, compounds obtained by the method according to the present invention are provided. The monoprotected bifunctional prodrug is used for preparing antibody drug conjugates composed of an antibody moiety and the monoprotected bifunctional prodrug. The antibody compound conjugates thus obtained are provided. Further, a method of preparing an antibody drug conjugate composed of two identical or two different antibody moieties is provided as well as the antibody compound conjugate containing two different antibody moieties accordingly. These conjugates can be used in pharmaceutical compositions, in particular, for use in treatment of tumors, e.g. for use in ADC therapy.

  • Patent number: 8940784
    Abstract: This invention relates to novel analogs of the DNA-binding alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and their conjugates. The conjugates are designed to release their (multiple) payload after one or more activation steps and/or at a rate and time span controlled by the conjugate in order to selectively deliver and/or controllably release one or more of said DNA alkylating agents. The agents, conjugates, and intermediates can be used to treat an illness that is characterized by undesired (cell) proliferation. As an example, the agents and the conjugates of this invention may be used to treat a tumor.

  • Patent number: 7214685
    Abstract: The chemotherapy of malignant tumours is greatly restricted by the generally slight differentiation of the available cytostatic agents between normal and malignant tissue. In order to achieve an improvement of the selectivity in cancer therapy, novel prodrugs have been developed from 6-hydroxy-2,3-dihydro-1H-indolene, 5-hydroxy-1,2-dihydro-3H-pyrrolo[3,2-e]indolene and 5-hydroxy-1,2-dihydro-3H-benzo[e]indolene as well as from 6-hydroxy-1,2,3,4-tetrahydro-benzo[f]-quinolines, that may be used within the framework of the ADEP therapy (antibody directed enzyme prodrug therapy). The new prodrugs are characterised by a high difference in toxicity between the prodrug and underlying drug and by a very high efficacy of the drug. After splitting off of the glycosidic and/or acetal group on the phenolic hydroxy groups of the prodrugs, a spirocyclopropacyclohexadiene is formed which, being a highly toxic group, effects an alkylation of the DNA or RNA.

The new prodrugs are characterised by a high difference in toxicity between the prodrug and underlying drug and by a very high efficacy of the drug. The high selectivity of the new prodrugs is probably attributed to the fact that, in the new prodrugs, a secondary halide is present in contrast to the prodrugs of a similar type previously produced by us.

  • Patent number: 5976857
    Abstract: Formation of an intramolecular cross-link in enzyme donor polypeptide fragments of .beta.-galactosidase, thereby forming a cyclic enzyme donor which is hindered from complementation with an enzyme acceptor fragment to form active of .beta.-galactosidase. The cyclic enzyme donor can be linearized by cleaving to restore complementation ability. Assays in which such cyclic enzyme donors are linearized by specific analytes are disclosed, as well as novel homobifunctional bis-maleimido cross-linking agents of the formula ##STR1## wherein R is hydroxy or acetate.
