Versatile Method for the Detection of Covalently Bound Substrates on Solid Supports by DART Mass Spectrometry
摘要:
Analysis of substrates directly on solid phase resins without the need for separate cleavage conditions remains an outstanding challenge In the field of solid phase synthesis. We now present the first example of simultaneous cleavage and mass spectrometric analysis of peptides from solid supports using direct analysis in real time (DART) mass spectrometry. We have shown that this method is compatible with a diverse array of solid phase resins and is suitable for analysis of both peptides and organic substrates.
highly over-expressed on PCa cells, is an excellent target for selective imaging of PCa. In recent years, various scaffolds have been explored as potential carriers to target diagnostic and therapeutic agents to PSMA+ tumour cells. Numerous fluorescent or radioisotope probes linked via a peptide linker have been developed that selectively binds to PCa cells. However, there are very few reports that examine

Mini lectins: A new class of oligosaccharidereceptors (see example) was designed by exploiting several modes of molecular recognition, including the unique ability of benzoboroxoles to complex hexopyranosides. The synthesis is modular, thus well suited to targeting specific oligosaccharides using combinatorial libraries.
