产品描述 | Stemazole is a novel small molecule human stem/progenitor cell proliferation activator that promotes the survival of human embryonic stem cells and maintains stemness, and promotes the survival of oligodendrocyte precursor cells in vitro. Stemazole significantly increased cell survival and clone formation in a dose-dependent manner, reduced apoptosis, and promoted recovery of motor dysfunction and myelin repair. Stemazole can be used as a therapeutic agent in demyelinating disorders, promoting OPC survival in vitro and regeneration in vivo. |
体外活性 | Stemazole (10, 30, and 100 μM) enhanced clonal expansion from single cells in a dose-dependent fashion and clearly decreased apoptosis from 54.1% to 25.2%. Furthermore, the drug reduced apoptosis from 43.6% to 8.4% over 15 h of starvation, with 66% of astemizole-treated cells remaining viable after 2 weeks of starvation. Importantly, starved cells protected with stemazole retained the same proliferation and differentiation properties as cells in normal culture. Stemazole significantly promotes the survival of stem cells in single-cell or starvation cultures without compromising stemness and pluripotency.[2] |
体内活性 | Mice were injected intraperitoneally with MPTP (20mg/kg) four times at 2-h intervals for one day to induce Parkinsonism, and then treated with stemazole (ST) (10, 30 and 50mg/kg) for 7 days. Our results demonstrated that ST treatment improved locomotor activity and motor coordination in MPTP mice. There was also a significant increase in TH-positive cells (∼24%, P<0.01) and DAT levels (∼26%, P<0.01) in MPTP mice treated with ST (50mg/kg) compared with the vehicle group. DA and its metabolite levels were significantly increased with ST (50mg/kg) treatment (P<0.01, compared with the vehicle group). SOD and GSH-PX activities were elevated notably in ST treatment groups compared with the vehicle group. These results suggest that ST has neuroprotective effect on the impaired DA system, potentially through enhancement of the cell's anti-oxidative capacity.[1] |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
