Fluorophore-Dapagliflozin Dyad for Detecting Diabetic Liver/Kidney Damages via Fluorescent Imaging and Treating Diabetes via Inhibiting SGLT2.

Type II diabetes is a prevalent disease; if left untreated, it could cause serious complications including liver and kidney damages. Hence, early diagnosis for these damages and effective treatment of diabetes are of high importance. Herein, a fluorophore-dapagliflozin dyad (DX-B-DA) has been developed as a theranostic system that can be triggered by intrahepatic/intrarenal reactive oxygen species (ROS) to concomitantly release a near-infrared (NIR) fluorescent dye (DX) and a SGLT2 inhibitor dapagliflozin (DA).

A Fluorescent Probe with Aggregation-Induced Emission for Detecting Alkaline Phosphatase and Cell Imaging.

Alkaline phosphatase (ALP) is associated with many diseases, and its accurate detection is of great significance. Fluorescent compounds with aggregation-induced emission (AIE) feature show beneficial advantages for serving as fluorescent probes. Herein, an AIE-active "turn on" probe for ALP detection was synthesized through incorporating a strong electron-withdrawing group (cyano) in the middle and the recognition moiety phosphate group at the end, thereby rendering a D-A-D structure with a relatively high conjugation degree and good water solubility.
