A Photolabile Linker for the Mild and Selective Cleavage of Enriched Biomolecules from Solid Support
摘要:
Selective release of enriched biomolecules from solid support is a desirable goal in proteomic and metabolomic studies. Here we demonstrate that photocleavage of a light-sensitive phenacyl ester bond is a suitable alternative cleavage strategy for the selective release of enriched biomolecules form avidin beads circumventing the disadvantages of conventional heat denaturation procedures.
Mmm, a reaction sandwich…︁ Using an immunoassay‐based technique able to monitor any kind of cross‐coupling reaction, a systematic and rapid evaluation of a large panel of random reactions was carried out. This approach led to the discovery of two new copper‐promoted reactions: a desulfurization reaction of thioureas leading to isoureas and a cyclization reaction leading to thiazole derivatives from

The invention relates to solid supports useful in medical applications that provide controlled release of drugs, such as peptides, nucleic acids and small molecules. The drugs are covalently coupled to the solid support through a linkage that releases the drug or a prodrug through controlled beta elimination.
henylazo)benzoic acid (HAZA) scaffold, the orthogonally protected difunctional azo–arene cleavablelinker 26 was designed and synthesized. Selective linker deprotection and derivatization was performed by introducing an alkyne reactive group and a biotin affinity tag. This optimized azo–arene cleavablelinker led to a total cleavage in less than 10 s with only 1 mM dithionite. Similar results were
