Reactive Metabolite Detection Studies: Cysteine Trapping

WebWe performed a systematic exploration of the role for the warhead group, introducing different cysteine-trapping fragments at position 6 of a traditional 4-anilinoquinazoline scaffold. We found that different reactive groups, including epoxyamides (compounds 3−6) and phenoxyacetamides (compounds 7−9), were able to irreversibly inhibit EGFR. WebThiol-reactive dyes are principally used to label proteins for the detection of conformational changes, assembly of multisubunit complexes and ligand-binding processes.ref In the case of proteins and peptides, the primary targets of thiol-reactive probes are cysteine residues.
