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.

The present invention relates to pyrrolo[1,4]benzodiazepine (PBD) dimer conjugates, to the compositions comprising them and to their therapeutic application, in particular as anticancer agents. The invention also relates to the process for the preparation of the conjugates, to their application as anticancer agents and to the dimers themselves.
Provided herein are mertansine polypeptide conjugates useful in the treatment of cancer, pharmaceutical compositions comprising the same, and methods of use and preparation thereof. The methods provided herein are highly N-terminal selective and are capable of yielding N-terminal mertansine conjugated polypeptides with site selectivity of 99% or greater.
