Biological Activity:

PYR-41 is a specific and cell permeable inhibitor of ubiquitin-activating enzyme E1 with an IC50 of < 10 uM, with no or little activity against E2. It blocks ubiquitylation and prevents ubiquitin-mediated proteasomal degradation. It inhibits NF-κB activation, blocks degradation of p53, increases p21 levels and induces apoptosis in vitro. PYR-41 can also cause an increase in sumoylation of proteins.

How to Use:

  • In vitro:PYR-41 was used at 10-50 µM final concentration in various in vitro assays.
  • In vivo: n/a

Xcess新型高效神经保护分子P7C32014年10月13日03:55  | 新闻印刷版刚刚在上个月的Cell中发表,最近关于神经保护小分子P7C3的 MOA研究具有广泛的体外和体内活性,为研究共享其他常见组织的神经系统疾病,损伤,发育和退行性疾病提供了新的令人兴奋的机会机制。  P7C3 是直接从体内神经发生筛选中鉴定出的无毒,稳定且可口服生物利用的合成小分子。它可以保护齿状回中的新生神经元,并刺激新神经元的生长。它还可以增强老年大鼠的学习和记忆能力。在爆炸介导的创伤性脑损伤(TBI)的啮齿动物模型中,P7C3还可以在损伤后,在神经元细胞死亡发生之前保持轴突的完整性。MOA研究表明P7C3可以结合烟酰胺磷酸核糖基转移酶(NAMPT),这是一种将烟酰胺转化为烟酰胺腺嘌呤二核苷酸(NAD)的限速酶。将活性P7C3化学物质施用至用阿霉素处理的细胞(诱导NAD耗竭),可导致细胞内NAD水平反弹,并免受阿霉素介导的毒性的影响。  如何订购:  Xcess Biosciences是一家领先的试剂和服务公司,提供10 mM DMSO溶液和以克计的固体形式的化合物。请访问我们的网站以获取订单信息和其他创新产品。特别是Xcess Biosciences继续向我们的表观遗传调节剂工具箱  (现在我们提供72种独特的化合物)和  泛素调节剂工具箱  (现在我们提供15种独特的化合物)中添加了更多新颖的小分子化学探针  。
