The invention provides compounds comprising a therapeutic agent coupled to a carrier molecule, with a minimum coupling ratio of 5: 1; wherein the carrier molecule is (i) an antibody fragment or derivative thereof or (ii) an antibody mimetic or derivative thereof; and wherein the therapeutic agents are coupled onto a lysine amino acid residue; and further wherein the therapeutic agent is not a photosensitising agent. There is also provided uses, methods relating to such compounds, as well as processes for their manufacture.

Herein we disclose the transformation of maleimides into water-soluble tris(2-carboxyethyl)phosphonium ylides and their subsequent application in the bioconjugation of protein- and peptide-linked aldehydes. The new entry into Wittig bioconjugate chemistry proceeds under mild conditions and relies on highly water soluble reagents, which are likely already part of most biochemists’ inventory.

surprisingly conserved function of the number of intracellular doxorubicin molecules, resulting in single-cell IC50 values of 4-12 million intracellular doxorubicin molecules. The developed assay is a straightforward method for understanding a drug's single-cellpotency and can be used for any fluorescent or fluorescently labeled drug, including nanoparticles or antibody-drug conjugates.
