VO-Ohpic trihydrate
CAS No. : 476310-60-8
MCE 国际站:VO-Ohpic trihydrate
产品活性:VO-Ohpic trihydrate 是一种高效的 PTEN 抑制剂,IC50 为 46±10 nM。
研究领域:PI3K/Akt/mTOR | Autophagy
In Vitro: VO-OHpic with two OHpic ligands and an oxo ligand is a sterically demanding molecule, and one will therefore expect that binds substrate will affect the subsequent binding of the inhibitor due to steric hindrance. VO-OHpic significantly inhibits PTEN activity in low nanomolar concentrations (IC50, 46±10 nM), which is in agreement with the previously determined potency (IC50, 35±2 nM) in a PIP3-based assay. The inhibition constants Kic and Kiu are determined to be 27±6 and 45±11 nM, respectively. VO-OHpic is an encouragingly specific and potent PTEN inhibitor. VO-OHpic is the most potent inhibitor (IC50=35 nM) of the PTEN lipid phosphatase activity.
In Vivo: PTEN is inhibited in mice by intra-peritoneal injection of VO-OHpic (10 μg/kg) 30 min before ischemia and then exposed them to 30 min of ischemia and 120 min of reperfusion. At the end of the experiment, myocardial infarct size is measured by triphenyltetrazolium chloride (TTC). Myocardial infarct size is significantly decreased in VO-treated mice (25±6 vs. 56±5 %, n=7, P<0.01). There is no difference in the area at risk between these two groups (46±3 vs. 57±3 %, n=7, P>0.05).

质分子,最终由于它们被排阻和扩散的程度不同,在凝胶柱中所经过的路程和时间也不同,从而彼此可以分离开来。 如果假定蛋白质分子近于球形,同时没有显著的水合作用,则不同大小分子量的蛋白质,在洗脱时峰的位置和该物质相对分子质量有直接的定量的关系。在一根凝胶柱中,凝胶颗粒间空隙所含水相体积为外水体积VO,不能进入凝胶孔径的那些大分子,当洗脱体积为时VO,出现洗脱峰。 凝胶颗粒内部孔穴的总体积为内水体积Vi,能全部渗入凝胶的那些小分子,当洗脱体积为VO+Vi时,出现洗脱峰。 利用
