Abstract
Thalidomide, a widely used ligand for cereblon (CRBN), has been gaining attention for its targeted protein degradation. In this study, we aimed to improve the optical and biocompatible features of hydrazine fluorescent probes by a novel probe called TH-1, based on the thalidomide moiety. Our results demonstrate that TH-1 exhibits remarkable properties including significant colorimetric changes, a fast response time, excellent selectivity, and high sensitivity as a hydrazine fluorescent probe. The mechanism by which TH-1 senses hydrazine has been convincingly verified. Notably, we have successfully applied TH-1 for bioimaging of hydrazine in living A549 cells, highlighting its practical significance. Moreover, the utilization of thalidomide, a clinically approved drug, as a fluorescent skeleton has expanded the repertoire of fluorescent skeleton libraries, paving the way for further on fluorescent probes.
