  • Patent number: 11419944
    Abstract: The present invention relates to linker-drug compounds (LDs) and antibody-drug conjugates (ADCs) comprising a non-linear self-immolative linker, which is cleavable or transformable under appropriate conditions and which reduces the hydrophobicity of the antibody-drug conjugate.
    Type: Grant

  • Patent number: 9901567
    Abstract: This invention relates to novel agents that are analogs of the DNA-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: 9890159
    Abstract: The present invention relates to a process comprising converting a compound of formula (I) into a compound of formula (II) by reaction with an organolithium reagent, which compound can be further converted into duocarmycin analogs consisting of a DNA-alkylating and a DNA-binding part, and still further into corresponding antibody-drug conjugates.
