英文摘要this study aimed to develop a practical ratiometric fluorescent probe for highly selective and sensitive detection of human udp-glucuronosyltransferase 1a1 (ugt1a1), one of the most important phase ii enzymes. 4-hydroxy-1,8-naphthalimide (hn) was selected as the fluorophore for this study because it possesses intramolecular charge transfer (ict) feature and displays outstanding optical properties. a series of n-substituted derivatives with various hydrophobic, acidic and basic groups were designed and synthesized to evaluate the selectivity of hn derivatives toward ugt1a1. our results demonstrated that the introduction of an acidic group to hn could significantly improve the selectivity of ugt1a1. among the synthesized fluorescent probes, nchn (n-3-carboxy propy1-4-hydroxy-1,8-naphthalimide) displayed the best combination of selectivity, sensitivity and ratiometric fluorescence response following ugt1a1-catalyzed glucuronidation. ugt1a1-catalyzed nchn-4-o-glucuronidation generated a single fluorescent product with a high quantum yield (phi=0.688) and brought remarkable changes in both color and fluorescence in comparison with the parental substrate. the newly developed probe has been successfully applied for sensitive measurements of ugt1a1 activities in human liver preparations, as well as for rapid screening of ugt1a1 modulators, using variable enzyme sources. furthermore, its potential applications for live imaging of endogenous ugt1a1in cells have also been demonstrated.
