Abstract:

Off-label use of 3-hydroxythalidomide draws more and more attentions due to its known biocompatibility, the metabolic pathway and the unique binding mode to CRBN protein. However, there is rare report about the application in analysis field. Herein, the off-label use of 3-hydroxythalidomide in the field of chemosensor was investigated. We designed and synthesized a H2O2 probe 2-(2,6-dioxopiperidin-3-yl)-4-{[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-benzyl]oxy}isoindoline-1,3-dione with fluorescent properties, using the old drug 3-hydroxythali-domide as parent compound. Based on the analysis, the probe has high selectivity and sensitivity for H2O2 over other analysts based on the exited state intramolecular proton transfer mechanism. Furthermore, the probe has good selectivity towards other analysts with a limit of detection(LOD) of 9.8 nmol/L, and it was successfully used in the detection of H2O2 in cosmetics samples, water samples and sewage samples. Meanwhile, we revealed the sensoring mechanism through the spectrum technology and the theoretic calculations.
