A naphthalimide-based glyoxal hydrazone for selective fluorescence turn-on sensing of Cys and Hcy.
A fluorescent turn-on probe for Cys/Hcy based on inhibiting the C═N isomerization quenching process by an intramolecular hydrogen bond was reported. The probe exhibited higher selectivity toward Cys/Hcy over other amino acids as well as thiol-containing compounds.
