, (2021/04/17)
The present invention provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In another aspect, the present invention provides bifunctional compounds that can be used to promote or enhance degradation of certain autoantibodies. In certain embodiments, treatment or management of a disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein or the autoantibody in the subject. Thus, in certain embodiments, administration of a compound of the invention to the subject removes or reduces the circulation concentration of the circulating protein or the autoantibody, thus treating, ameliorating, or preventing the disease and/or disorder. In certain embodiments, the circulating protein is TNF.

Herein we describe the design and synthesis of the first series of di-functional ligands for the directed construction of inorganic-protein frameworks. The synthesized ligands are composed of a metal-ion binding moiety (terpyridine-based) conjugated to an epoxysuccinyl peptide, known to covalently bind active cysteine proteases through the active-site cysteine. We explore and optimize two different conjugation chemistries between the di-functionalized metal-ion ligand and the epoxysuccinyl-containing peptide moiety: peptide-bond formation (with limited success) and Cu'-catalysed click chemistry (with good results). Further, the complexation of the synthesized ligands with Fe" and NiII" ions is investigated: the di-functional ligands are confirmed to behave similarly to the parent terpyridine. As designed, the peptidic moiety does not interfere with the complexation reaction, in spite of the presence of two triazole rings that result from the click reaction. ES-MS together with NMR and UV/Vis stud-ies establish the structure, the stoichiometry of the complexation reactions, as well as the conditions under which chemically sensitive peptide-containing polypyridine ligands can undergo the self-assembly process. These results establish the versatility of our approach and open the way to the synthesis of di-functional ligands containing more elaborated polypyridine ligands as well as affinity labels for different enzyme families. As such, this paper is the first step towards the construction of robust supramolecular species that cover a size-regime and organization level previously unexplored.
