Patents by Inventor Franciscus Marinus Hendrikus De Groot

Franciscus Marinus Hendrikus De Groot has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11052155
    Abstract: This invention relates to novel analogs of the DNA-alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and 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.

  • Patent number: 7705045
    Abstract: This invention concerns multiple release spacers and spacer systems, which release multiple leaving groups following a single activation. It concerns compounds comprising a specifier linked to two or more of the same or different leaving groups (L in the figure) via a self-eliminating multiple release spacer or spacer system, which compounds upon a single activation step, in particular removal or transformation of the specifier, release at least two leaving groups.
