The synthesis and properties of four new fluorescent reagents capable of forming moderately stable links to the 3' oxidized end of RNA are reported. All are hydrazide derivatives: pyrene butyric acid hydrazide, proflavine monosemicarbazide, proflavine monosuccinic acid hydrazide, and anthracene-9-carboxaldehyde carbohydrazone. In addition, procedures are given for coupling the bifunctional reag...

Small-molecule thiols, such as cysteine (CYS) and glutathione (GSH), are essential for maintaining the cellular redox environment and play important roles in regulating various cellular physiological functions. A fluorescence probe (compound 1-Cu2+) for thiols based on coumarin carbohydrazide dinuclear copper complex was developed. Compound 1 was synthesized from the reaction of 7-(diethylamino...
