Development of novel linkers to conjugate pharmacophores to a carrier antibody
摘要:
We have developed modified maleimide novel linkers with improved chemical stability that could potentially be used in conjugating various pharmacophores such as oligo nucleotides, peptides, and proteins to antibodies to afford novel biologics with well-defined therapeutic benefits and improved pharmacokinetic properties. These linkers expand the array of tools available for bioconjugation of pharmacophores to antibodies. (C) 2012 Elsevier Ltd. All rights reserved.
The present invention provides a FGF21 molecule covalently attached to the combining site of an antibody via a linker, wherein the linker is covalently attached to the side chain of a linking residue within FGF21. Various uses of the compounds are provided, including methods to prevent or treat diabetes or diabetes-related conditions.
