Abstract

Attempts to characterize potential biologically important covalent interactions between electrophilic quinones derived from catechols present in poison &/ivy (urushiol) and biomacromolecules have led to the analysis of model reactions involving sulfur and amino nucleophiles with 3-heptadecylbenzoquinone. Characterization of the reaction products indicates that this quinone undergoes regiospecific attack by (S)-N-acetylcysteine at C-6 ...
