Abstract:Competitive proteome profiling is a powerful approach for the identification of targets of small molecules. This approach usually employs an inhibitor‐derived probe or a cysteine‐reactive probe such as an IA‐alkyne in a comparison between inhibitor‐treated and untreated samples, thus enabling distinction between genuine targets and nonspecific labeling. We have developed an active probe derived from an EGFR inhibitor, afatinib, and a cysteine reactive probe, an alkyne‐containing α,β‐unsaturated amide, to compa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
