摘要 |
<p>The present invention is directed to methods for formation of a chemically programmed antibody comprising the steps of: (1) reacting a conjugate comprising a signal module covalently linked to a proadapter with a catalytic moiety selected from the group consisting of a catalytic antibody and a Fab fragment of a catalytic antibody, wherein the proadapter includes therein a precursor to a reactive moiety activated to a reactive moiety by a reaction catalyzed by the catalytic moiety; and (2) crosslinking the reactive moiety to a side chain of an amino acid residue in the active site of the catalytic moiety to produce the chemically programmed antibody. The invention also encompasses chemically programmed antibodies formed by these methods, methods for their use, and pharmaceutical compositions, as well as proadaptors and conjugates including them. Chemically programmed antibodies are useful for the treatment of cancer, particularly in metastasis.</p> |
