Cystamine is the disulfide form of the free thiol, cysteamine. Cystamine is an orally active transglutaminase (Tgase) inhibitor. Cystamine also has inhibition activity for caspase-3 with an IC 50 value of 23.6 μM. Cystamine can be used for the research of severals diseases including Huntingtons disease (HD) .

体外研究(In Vitro)
Cystamine has inhibition activity for caspase-3 with an IC50 value of 23.6 μM.Cystamine (0-500 μM; 0-16 h) inhibits recombinant active caspase-3 in a concentration-dependent manner. Cystamine (250 μM; 10 h) robustly increases the levels of glutathione. has not independently confirmed the accuracy of these methods. They are for reference only.Western Blot Analysis
体内研究(In Vivo)
Cystamine (oral, i.p.; 112, 225 mg/kg) reduces Tgase activity and GGEL levels, lessens the behavioral and neuropathological severity, and extends survival in R6/2 transgenic HD mice. has not independently confirmed the accuracy of these methods. They are for reference only.
