Description and Uses
Cysteamine is a stable aminothiol with radioprotective activities. It reduces ionizing radiation-induced death and chromosomal damage in mice in a dose-dependent manner. Cysteamine binds rapidly and temporarily to plasma proteins upon administration and this activity is directly correlated to its radioprotective effects. In vitro, 0.1 mM cysteamine depletes 90% of free cystine from cystinotic fibroblasts. Formulations containing cysteamine have been used to treat nephropathic cystinosis and reduce glomerular deterioration in humans.
Cysteamine hydrochloride has been used in the in-situ generation of chiral cysteamine-capped cadmium sulfide quantum dots (CA-CdS QDs) for the sensing of Cd2+ and S2-.
