产品描述 | PAC-1 (Procaspase activating compound 1) has been used in trials studying the treatment of Lymphoma, Melanoma, Solid Tumors, Breast Cancer, and Thoracic Cancers, among others. |
靶点活性 | Procaspase-3:0.22 μM(EC50) |
体外活性 | PAC-1由于激活procaspase-3和随后诱导凋亡发挥体内抗肿瘤效果,与体外活性一致.用5 mg的稳定释放低剂量PAC-1处理小鼠,明显抑制ACHN肾移植瘤生长.用50或100 mg/kg PAC-1口服处理,明显剂量依赖性阻碍NCI-H226肺癌移植瘤生长,且明显阻止癌细胞浸润肺组织. |
体内活性 | PAC-1能够以延迟的方式诱导Bax/Bak双敲除细胞和Bcl-2和Bcl-xL过表达细胞中的细胞死亡,具有与野生型对应物相同的功效。PAC-1按caspase-3 非依赖性方式诱导细胞色素c释放,随后触发下游caspase-3激活和细胞死亡。PAC-1不能诱导Apaf-1敲除细胞中的细胞死亡和半胱天冬酶-3激活,这表明凋亡体形成对于通过PAC-1介导的细胞死亡的胱天蛋白酶-3激活是必需的。PAC-1诱导原发性癌细胞凋亡,IC50值为3 nM至1.41 μM,比邻近的非癌细胞更有效,IC50为5.02 μM至9.98 μM,这也与procaspase-3的浓度直接相关。PAC-1激活procaspase-3,产生caspase-3,EC50为 0.22 μM,且激活procaspase-7,EC50为 4.5 μM。癌细胞系中增高的caspase 3水平使 PAC-1 选择性诱导凋亡,按与procaspase-3 浓度成比例的方式,NCI-H226细胞的IC50为0.35 μM,UACC-62细胞的IC50为约3.5 μM。PAC-1通过螯合锌离子来激活胱天蛋白酶-3,从而减轻锌介导的抑制作用,并允许胱天蛋白酶原-3自身激活为胱天蛋白酶-3。 |
激酶实验 | In vitro procaspase-3 activation: Procaspase-3 is expressed and purified in Escherichia coli. Various concentrations of PAC-1 are added to 90 μL of a 50 ng/mL of procaspase-3 in caspase assay buffer in a 96-well plate, The plate is incubated for 12 hours at 37 °C. A 10 μL volume of a 2 mM solution of caspase-3 peptidic substrate acetyl Asp-Glu-Val-Asp-p-nitroanilide (Ac-DEVD-pNa) in caspase assay buffer is then added to each well. The plate is read every 2 minutes at 405 nm for 2 hours in a Spectra Max Plus 384 well plate reader. The slope of the linear portion for each well is determined, and the relative increase in activation from untreated control wells is calculated. |
细胞实验 | Cells are exposed to various concentrations of PAC-1 for 72 hours. Cell death is quantified by the addition of MTS/PMS CellTiter 96 Cell Proliferation Assay reagent. The plates are incubated at 37 °C for approximately 1 hour (until the colored product formed), and the absorbance is measured at 490 n(Only for Reference) |

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。
