  • Cystamine (dihydrochloride) 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 IC50 value of 23.6 μM. Cystamine can be used for the research of severals diseases including Huntington's disease (HD) [1][2][3].

Caspase 3:23.6 μM (IC50)

In Vitro Cystamine (dihydrochloride) has inhibition activity for caspase-3 with an IC50 value of 23.6 μM[1]. Cystamine (0-500 μM; 0-16 h) inhibits recombinant active caspase-3 in a concentration-dependent manner[1]. Cystamine (250 μM; 10 h) robustly increases the levels of glutathione[1]. Western Blot Analysis[1] Cell Line: Human neuroblastoma SH-SY5Y cells Concentration: 250, 500 μM Incubation Time: 0-16 h Result: Inhibited the MG132-mediated activation of caspase-3. Inhibited the H2O2-mediated activation of caspase-3. Inhibited caspase-3 activity in a tTG-independent manner.
In Vivo Cystamine (dihydrochloride) (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[2]. Animal Model: R6/2 transgenic HD mice[2] Dosage: 112, 225 mg/kg Administration: Intraperitoneal or oral, daily Result: Significantly extended survival, improved body weight and motor performance, delayed the neuropathological sequela and significantly altered the levels of Tgase activity and N(Sigma)-(gamma-L-glutamyl)-L-lysine (GGEL) levels.
