Methods for Rapid and Ultra-rapid Electrophilic Cysteine Arylation
Abstract
This presentation will describe a series of cationic reagents that enable rapid arylation of cysteine under mild conditions compatible with proteins and peptides. These uncatalyzed reactions can proceed with exceptionally high rate constants in pH 7.0 aqueous buffer at 25 °C. Such reactions allow for stoichiometric bioconjugation of micromolar cysteine within minutes or even seconds. Even though the arylation is extremely fast, the chemistry exhibits excellent selectivity, thus furnishing functionalized peptides and proteins with both high conversion and purity.
