产品描述 | Torin 2(IC50=0.25 nM), a specific and effective mTOR inhibitor, is the 800-fold greater specific activity for mTOR than PI3K and improves pharmacokinetic properties. The EC50 of Torin 2 for ATM/ATR/DNA-PK inhibition is 28 nM/35 nM/118 nM, respectively. |
靶点活性 | mTOR:0.25 nM, ATR:35 nM(EC50), DNA-PK:118 nM(EC50), ATM:28 nM(EC50) |
体外活性 | 在Th-MYCN 小鼠体内,Torin 2(20 mg/kg)消除MYCN肿瘤,减少MYCN蛋白质水平,并诱导细胞凋亡.在小鼠肝微粒体稳定性试验中,Torin 2表现出>95%的药效学响应,半衰期为11.7分钟.在雄性Swiss albino小鼠中,静脉内或口服Torin 2后,体内表现出最好的生物利用度为51%,半衰期为0.72小时,和低清除率是19.6 mL/min/kg. |
体内活性 | 在MZ-CRC-1和TT细胞中, Torin 2(< 50 nM)引起细胞的的活性明显减少,Torin 2(100 nM)使细胞的迁移明显减少。Torin 2抑制mTORC1,因此通过促进其核转运激活TFEB,EC50为1.666 mM。Torin 2与PI3Kγ具有相同的结合模式,V882作为铰链结合点,在内部疏水袋Y867,D841 和D964再提供三个作用于氨基比林侧链的氢键,类似于mTOR的Y2225,D2195 和D2357。 |
激酶实验 | mTOR and PI3K Cellular Assays: Cellular IC50 values for mTOR are determined using p53?/? MEFs. Cells are treated with vehicle or increasing concentrations of Torin 2 for 1 h and then lyse. Phosphorylation of S6K1 Thr-389 is monitored by immunoblotting using a phospho-specific antibody. Meanwhile, cellular IC50 values for PI3Ka are determined based on phosphorylation of Akt Thr-308 in p53?/?/mLST8?/? MEFs or human PC3 cells expressing the S473D mutant of Akt1. |
细胞实验 | For viability, MZ-CRC-1 and TT cells are seeded in quadruplicate in 96-well plates (1.0×104 cells per well) in culture media with 2.5% and 4% FBS, respectively. After 24 hours, cells are treated with Torin 2. At the indicated time point, cells are incubated for 3 hours with 10 μL of CellTiter96 AQueous One solution in 100 μL of culture media and absorbance is measured at 490 nm.(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。
