摘要: N-(3-Azidopropyl)vinylsulfonamide was developed as a new bifunctional bioconjugation reagent suitable for the cross-linking of biomolecules through copper(I)-catalyzed azide-alkyne cycloaddition and thiol Michael addition reactions under biorthogonal conditions. The is easily clicked to an acetylene-containing DNA or protein then reacts with cysteine-containing peptides proteins form covalent cross-links. Several examples bioconjugations ethynyl- octadiynyl-modified peptides, p53 protein, alkyne-modified human carbonic anhydrase are given.
