Application

Cysteamine is suitable for use:
  • in the preparation of cysteamine modified gold nanoparticles (AuNP)
  • in the fabrication of SU-8 microrods, where in, the amine group of cysteamine reacts with the unreacted epoxide rings present on the surface of the particles, thereby opening it and forming a covalent bond
  • to enhance in vitro development of porcine oocytes matured and fertilized in vitro
  • in a study to demonstrate the depletion effect of cysteamine on cystinotic leucocyte granular fractions of cystine by disulphide interchange
  • as a radioprotector
  • to administer subcutaneously in rats to study its blocking effect on somatostatin secretion without modifying the pancreatic insulin or glucagon content
  • as a scavenger in electrophoretic gels (acetic acid/urea gels)

Biochem/physiol Actions

Cysteamine (β-mercaptoethylamine) depletes cystine from patient′s cells and there by regulates renal glomerular function and increases growth in them. Therefore, cysteamine is considered to be a potential therapeutic for nephropathic cystinosis.

Cystinotic lysosome-rich leucocyte granular fractions, loaded with [35S]cystine, were exposed to different cystine-depleting agents. During a 30 min incubation at 37 degrees C, untreated cystinotic granular fractions lost negligible [35S]cystine when corrected for lysosome rupture. Granular fractions exposed to 0.1

Most porcine oocytes matured and fertilized in vitro fail to develop normally due to abnormal fertilization. The aim of this study was to determine the effect of cysteamine on pronuclear formation and developmental competence in pig embryos produced in vitro.

Cysteamine (300 mg/kg) administered subcutaneously depletes pancreatic somatostatin to 36% of control levels, but does not alter pancreatic insulin or glucagon content. Although perfusion of pancreata from normal animals with glucose (300 mg/dl) markedly stimulated somatostatin release, pancreata from cysteamine-treated
