Description

General description

Cysteamine is an aminothiol that can reduce important oxidized disulfide molecules such as cystine to yield cysteine.

Application

Cysteamine is used in a wide range of applications such as regulation of gene expression, depletion of somatostatin and coating of nanoparticles. It may be used to study the potential value of cystine in metabolism disorders such as cystinosis. Cysteamine may be used as a redox sensitive component in biosensor development.

Other Notes

Aminothiol radioprotector; Inducer of duodenal ulcers in rodents; Depletes somatostatin concentration in rat tissues.
