4-Nitro-1,8-naphthalic anhydride (NNA) was used to distinguish cysteine from homocysteine and other potentially interfering thiols through a novel sequential substitution mechanism. The discrimination involves a blue-fluorescent thioether formation via nucleophilic aromatic substitution of the nitro group by thiol, followed by...

We have synthesized a series of coumarins (1-3) that can emit fluorescence in a turn-on manner through a Michael-type reaction with thiol-containing compounds. The only difference among the coumarins is the position of a carboxyl group on its benzene ring...
