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.
Ligand-directed selective protein modification based on local single-electron-transfer catalysis

A photocatalyst ([Ru(bpy)3]2+) bound to a protein ligand was essential for the title method. Local single-electron transfer from the catalyst resulted in the formation of tyrosyl radicals. N′-Acetyl-N,N- dimethyl-1,4-phenylenediamine was used as the tyrosyl radical trapping agent and used in a radical addition to afford selective modification of the target protein. Copyright
Synthesis and characterization of well-defined l-lactic acid-caprolactone co-oligomers and their rhenium (I) and technetium(I) conjugates

Staring from l-lactide and ε-caprolactone, the corresponding lactic-caprolactone cooligomer with hydroxyl and carboxylic acid groups were synthesized. These oligomers were connected with chelating groups through a long chain tether, ready for transition metal binding. Coordination of organometallic rhenium(I) and technetium(I) complexes generated the conjugates in high yield and short time, satisfying the requirements for short-lived radiopharmaceuticals in clinical applications. A reasonable pharmacophore model has been established to guide the design of well-defined lactic acid oligomer for nuclear medicine.

Selective synthesis of carbamate protected polyamines using alkyl phenyl carbonates

Utilising alkyl phenyl carbonates, an economical, practical and versatile method for selective Boc, Cbz and Alloc protection of polyamines has been developed. This method allows Boc, Cbz and Alloc protection of primary amines in the presence of secondary amines by reaction of the polyamines with the alkyl phenyl carbonates. Also, this method allows mono carbamate protection of simple symmetrical aliphatic α,ω-alkanediamines in high yields with respect to the diamine. Finally, the method allows selective carbamate protection of a primary amine located on a primary carbon in the presence of a primary amine located on a secondary or a tertiary carbon in excellent yields.
