Abstract
We herein report a novel class of dual enzyme-responsive fluorogenic probes based on two orthogonal deprotection reactions via the “covalent assembly” principle. Sensing of two different enzymes (hydrolase and nitroreductase) through domino reactions, producing the push–pull backbone of a fluorescent 3-substituted 7-hydroxy-2-iminocoumarin dye, is reported.
