The present application is directed to a therapeutic composition, comprising two precursor compounds (monomers) that are suitable for assembly via two or more reversible covalent bonds. The monomers are polyfunctionalized molecules comprising a bioorthogonal linker element and ligand or pharmacophore, wherein the linker and ligand/pharmacophore are covalently coupled to each other either directly or through an optional connector moiety.

process involves simultaneous optimization of the three principle degrader components: E3 ubiquitin ligaseligand, linker, and protein of interest (POI) ligand. A substantial degree of commonality exists with the E3ligaseligands typically used at the early stages of degrader development, resulting in demand for these compounds as chemical building blocks in degrader research programs. We describe
Supramolecular polymers have shown to be powerful scaffolds for tissue engineering applications. Supramolecular biomaterials functionalized with ureidopyrimidinone (UPy) moieties, which dimerize via quadruple hydrogen-bond formation, are eminently suitable for this purpose. The conjugation of the UPy moiety to biologically active peptides ensures adequate integration into the supramolecular UPy polymer matrix. The structural complexity of UPy-peptide conjugates makes their synthesis challenging and until recently low yielding, thus restricted the access to structurally diverse derivatives. Here we report optimization studies of a convergent solid-phase based synthesis of UPy-modified peptides. The peptide moiety is synthesized using standard Fmoc solid-phase synthesis and the UPy fragment is introduced on the solid-phase simplifying the synthesis and purification of the final UPy-peptide conjugate. The convergent nature of the synthesis reduces the number of synthetic steps in the longest linear sequence compared to other synthetic approaches. We demonstrate the utility of the optimized route by synthesizing a diverse range of biologically active UPy-peptide bioconjugates in multimilligram scale for diverse biomaterial applications. 1 Introduction 2 Divergent Synthesis 3 Convergent Synthesis 4 UPy-Amine Strategy 5 UPy-Carboxylic Acid Strategy 6 Conclusion

Supramolecular synthesis represents a flexible approach to the generation of dynamic multicomponent materials with tunable properties. Here, cellular uptake systems based on dynamic supramolecular copolymers have been developed using a combination of differently functionalized discotic molecules. Discotics featuring peripheral amine functionalities that endow the supramolecular polymer with cellular uptake capabilities were readily synthesized. This enabled the uptake of otherwise cell-impermeable discotics via cotransport as a function of supramolecular coassembly. Dynamic multicomponent and multifunctional supramolecular polymers represent a novel and unique platform for modular cellular uptake systems.
