Using a 3-hydroxyflavone derivative as a fluorescent probe for the indirect determination of aminothiols separated by ion-pair HPLC

Homocysteine, cysteine, cysteinyl-glycine, and glutathione are aminothiols (ATs) that are marker-molecules in Down syndrome, Alzheimer's disease, or are implicated in a number of vascular diseases, thus rapid determination of these ATs is desirable.
