    生物活性

    Torin 2 is an mTOR inhibitor with EC50 of 0.25 nM for inhibiting cellular mTOR activity, and exhibits 800-fold selectivity over PI3K (EC50: 200 nM). Torin 2 also inhibits DNA-PK with an IC50 of 0.5 nM in the cell free assay. Torin 2 can suppress both mTORC1 and mTORC2.

    體內(nèi)研究

    Torin2 表現(xiàn)出良好的生物利用度和暴露,并且在單劑量 20 mg/kg 后可以維持對肺和肝臟中 mTOR 活性的強(qiáng)烈抑制至少 6 小時。Torin 2 更容易大規(guī)模生產(chǎn),并表現(xiàn)出改進(jìn)的藥代動力學(xué)特性,這應(yīng)該使其能夠用于體內(nèi)實驗[1]。Torin 2 強(qiáng)烈抑制 pS6K (T389) 和 p4EBP1 (T37/46) 并部分抑制 pAkt (T308)。用 25 mg/kg 的 AZD6244 處理小鼠可顯著抑制 pERK。Torin 2 (40 mg/kg) 和 AZD6244 (25 mg/kg) 的聯(lián)合給藥表現(xiàn)出對所有藥效學(xué)標(biāo)志物的強(qiáng)烈抑制[2]。用 Torin 2 和雷帕霉素處理可誘導(dǎo)星形膠質(zhì)細(xì)胞分泌 IL-6,并可能有助于減少 SCI 后的機(jī)械超敏反應(yīng)。Torin1 和 Torin 2 處理增加了 IL-6 mRNA,表明 PI3K-mTOR 通路是星形膠質(zhì)細(xì)胞中 IL-6 表達(dá)的負(fù)調(diào)節(jié)因子。重要的是,Torin 2 處理未顯示任何細(xì)胞毒性,因為通過 TUNEL 測定或通過蛋白質(zhì)印跡法檢測裂解半胱天冬酶 3 未觀察到細(xì)胞死亡跡象[3]。

    Cell Assay
    [2]

    HCT116 cells are treated with 100 nM Torin 2 or AZD8055 for 1 hour before they are thoroughly washed out by 3×PBS and 1×DMEM medium. Then cells are incubated in DMEM medium for indicated time before they are lysed and collected using M-PER. Protein concentrations are measured and equal amount of proteins are loaded. Experiments are repeated three times and one set of results[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [1][3]

    Mice[1]
    Six-week old male C57BL/6 mice are fasted overnight prior to Torin 2 treatment. The mice are treated with vehicle (for 10 h) or Torin 2 (20 mg/kg for 6h) via oral gavage and then re-fed 1 h prior to sacrifice (CO2 asphyxiation). Liver and lung are collected and frozen on dry ice. The frozen tissue is thawed on ice and lysed by sonication in tissue lysis buffer (50 mM HEPES, pH 7.4, 40 mM NaCl, 2 mM EDTA, 1.5 mM sodium orthovanadate, 50 mM sodium fluoride, 10 mM sodium pyrophosphate, 10 mM sodium β-glycerophosphate, 0.1% SDS, 1.0% sodium deoxycholate, and 1.0% Triton, supplemented with protease inhibitor cocktail tablets). The concentration of clear lysate is measured using the Bradford assay and samples are subsequently normalized by protein content and analyzed by SDS-PAGE and immunoblotting.
    Rats[3]
    Female rats (220 g) are group-housed 4 animals per cage, and kept on a 12-hour light/dark cycle with food and water ad libitum. Spinal cord injury is done with the Keck Center for Neurosciences impactor using a 10 g weight dropped from a height of 25 mm onto the dorsal surface of the exposed spinal cord. After recording BBB scores, withdrawal thresholds evoked by touch stimulus, and body weights for the first week post-injury, animals are divided into 5 treatment groups: na?ve (N=4), sham (N=6), vehicle (N=6), Torin 2 (N=6), and Torin 2+Rapamycin (N=8). Torin 2 alone (4 mg/kg) or in combination with Rapamycin (1.5 mg/kg) is administered orally by gavage once a day starting at day 15 after injury and ending at day 29. In sham operated rats only the laminectomy is performed.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
