A lysosome-targeting fluorescent probe to visualize endogenous and exogenous methylglyoxal in live cells and zebrafish

The development of a lysosome-targeting fluorescent probe to visualize endogenous and exogenous methylglyoxal (MGO) in live cells has important implications for associated diseases. Herein, a lysosome-targeting fluorescent probe MGO-Naph-A was designed and synthesized to detect MGO with high selectivity. The probe contained naphthalimide as the fluorescent group
