生物活性

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 Huntingtons disease (HD) .

体外研究(In Vitro)

Cystamine (dihydrochloride) 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.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis

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.
体内研究(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.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: R6/2 transgenic HD mice
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.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
