In this study, fluorescent deferasirox derivatives with unique photophysical properties were reported, and a fluorescent responsive pro-chelator was successfully developed for the detection of alkaline phosphatase. The diagnostic potential of these deferasirox derivatives in bacterial biofilm studies was demonstrated.
Deferasirox, ExJade, is an FDA-approved iron chelator used for the treatment of iron overload. In this work, we report several fluorescent deferasirox derivatives that display unique photophysical properties, i.e., aggregation-induced emission (AIE), excited state intramolecular proton transfer, charge transfer, and through-bond and through-space conjugation characteristics in aqueous media. Functionalization of the phenol units on the deferasirox scaffold afforded the fluorescent responsive pro-chelator ExPhos, which enabled the detection of the disease-based biomarker alkaline phosphatase (ALP). The diagnostic potential of these deferasirox derivatives was supported by bacterial biofilm studies.
