Protein Modification by Strain-Promoted Alkyne–Nitrone Cycloaddition**
The bioorthogonal chemical reporter strategy is emerging as a versatile method for the labeling of biomolecules, such as nucleic acids, lipids, carbohydrates, and proteins. In this approach, an abiotic chemical functionality (reporter) is incorporated into a target biomolecule and can then react with a complementary bioorthogonal functional group linked to one of a diverse set of probes. The az...
متن کاملN-Terminal dual protein functionalization by strain-promoted alkyne-nitrone cycloaddition.
Strain-promoted alkyne-nitrone cycloadditon (SPANC) was optimized as a versatile strategy for dual functionalization of peptides and proteins. The usefulness of the dual labeling protocol is first exemplified by the simultaneous introduction of a chloroquine and a stearyl moiety, two endosomal escape-improving functional groups, into the cell-penetrating peptide hLF (human lactoferrin). Additio...
متن کاملFast copper-free click DNA ligation by the ring-strain promoted alkyne-azide cycloaddition reaction.
Templated DNA strand ligation by the ring-strain promoted alkyne-azide [3+2] cycloaddition reaction is very fast; with dibenzocyclooctyne, the reaction is essentially complete in 1 min. It is inhibited by the presence of a single mismatched base pair suggesting applications in genetic analysis.
متن کاملInterfacial strain-promoted alkyne-azide cycloaddition (I-SPAAC) for the synthesis of nanomaterial hybrids.
An interfacial strain promoted azide-alkyne cycloaddition (I-SPACC) is introduced as a method to prepare robust nanomaterial hybrids. This is demonstrated with a reaction between a novel dibenzocyclooctyne-modified single walled carbon nanotubes (DBCO-SWCNT) and a versatile water-soluble azide modified gold nanoparticle (N3-EG4-AuNP).
متن کاملInducible, Site-Specific Protein Labeling by Tyrosine Oxidation–Strain-Promoted (4 + 2) Cycloaddition
Genetically encoded tyrosine (Y-tag) can be utilized as a latent anchor for inducible and site-selective conjugation. Upon oxidation of tyrosine with mushroom tyrosinase, strain-promoted cycloaddition (SPOCQ) of the resulting 1,2-quinone with various bicyclo[6.1.0]nonyne (BCN) derivatives led to efficient conjugation. The method was applied for fluorophore labeling of laminarinase A and for the...
