Peptide bond synthesis was performed on PEGA beads under microwave radiations. Classical chemical coupling as well as thermolysin catalyzed synthesis was studied, and the effect of microwave radiations on reaction kinetics, beads' integrity, and enzyme activity was assessed. Results demonstrate that microwave radiations can be profitably exploited to improve reaction kinetics in solid phase pep...

  Introduction: Radioimmunotherapy (RIT) is a very promising new therapy for the treatment of recurrent B-Cell non-Hodgkin's lymphoma (NHL). Iodine-131 is the most frequently used nuclide in clinical RIT, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. To circumvent this problem, we have synthesized a tr...

Segment condensations were performed to construct peptide fragments related to Sulfolobus solifataricus Ribonuclease. At each condensation step, the new protecting groups were stable. The protected peptide fragments were treated with a low-high HF procedure to give the desired peptide fragments. These peptide fragments were also prepared by the solid-phase method, and the obtained peptides were...

The synthesis of two ribonucleoprotein fragments of unprecedented complexity is reported. These hybrid biomolecules are prepared combining the use of an automated solid phase peptide and oligonucleotide synthesizer on a single solid support.

Dendritic structures, being highly homogeneous and symmetric, represent ideal scaffolds for the multimerization of bioactive molecules and thus enable the synthesis of compounds of high valency which are e.g., applicable in radiolabeled form as multivalent radiotracers for in vivo imaging. As the commonly applied solution phase synthesis of dendritic scaffolds is cumbersome and time-consuming, ...

Synthesis of the first self-immobilizing, fluorogenic unnatural amino acid that mimics phosphotyrosine (pTyr) is reported. By using solid-phase peptide synthesis, it was subsequently incorporated into peptide-based probes which found applications in bioimaging and fluorescence-activated cell sorting (FACS).

Current strategies for the synthesis of glycopeptides require multiple manual synthetic steps. Here, we describe a synthesis concept that merges solid phase peptide and oligosaccharide syntheses and can be executed automatically using a single instrument.

Synthesis of a novel unnatural amino acid (2-FMPT) for the solid-phase synthesis of peptide-based probes suitable for target-specific activity-based profiling of protein tyrosine phosphatases from crude proteomes is reported.
