N-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 کاملProtein 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 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...
متن کاملStrain-Promoted 1,3-Dipolar Cycloaddition of Cycloalkynes and Organic Azides
A nearly forgotten reaction discovered more than 60 years ago-the cycloaddition of a cyclic alkyne and an organic azide, leading to an aromatic triazole-enjoys a remarkable popularity. Originally discovered out of pure chemical curiosity, and dusted off early this century as an efficient and clean bioconjugation tool, the usefulness of cyclooctyne-azide cycloaddition is now adopted in a wide ra...
متن کاملSite-specific peptide and protein immobilization on surface plasmon resonance chips via strain-promoted cycloaddition.
Surface plasmon resonance (SPR) is a powerful label-free diagnostic tool to study biomolecular interactions. However, one of the drawbacks of SPR is the lack of controlled immobilization of ligands on the sensor surface. We have developed a modular platform for the fast, reagent-free and site-specific immobilization of azide-containing ligands by strain-promoted cycloaddition onto a cyclooctyne...
