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. WebJan 1, 2009 · A trapping approach for semi-quantitative assessment of bioactivation potential has been established for new chemical entities by using [ 35 S]cysteine and [ 14 C]sodium cyanide as trapping reagents. Reactive metabolites were trapped as radioactive adducts with the trapping reagents to be analyzed by radio-LC (/MS).
