    生物活性

    Paxalisib (GDC-0084) is a brain penetrant inhibitor of PI3K and mTOR, with Kis of 2 nM, 46 nM, 3 nM, 10 nM and 70 nM for PI3Kα PI3Kβ, PI3Kδ, PI3Kγ and mTOR, respectively[1].

    体外研究
    (In Vitro)

    Paxalisib (GDC-0084; Compound 16) maintains inhibition of each of the Class I PI3K isoforms but with more potent inhibition of mTOR. Paxalisib is also tested in five different GBM cell lines and is found to have antiproliferative EC50s ranging from 0.3 to 1.1 μM[1].

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

    体内研究
    (In Vivo)

    After a 25 mg/kg dose of Paxalisib (GDC-0084; Compound 16) administered orally, pAKT in normal mouse brain tissue is significantly inhibited at 1 and 6 h postdose. The potent inhibition of pAKT at both time points in this study demonstrates that Paxalisib inhibits its target behind a fully intact BBB. In addition to the pharmacodynamic effect in normal brain tissue, Paxalisib is studied in a subcutaneous U87 tumor xenograft model of glioblastoma in mice. In this study, Paxalisib achieves significant and dose-dependent tumor growth inhibition. Tumor growth inhibition is first observed at a 2.2 mg/kg dose level. Higher doses led to greater tumor growth inhibition, including tumor regressions at the 17.9 mg/kg dose level. Each of these doses is well tolerated for the duration of the study[1].

    动物实验:

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
    ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

    • 方案 一

      请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: 1 mg/mL (2.61 mM); 悬浊液; 超声助溶

      此方案可获得 1 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

      1 mL 工作液为例,取 100 μL 10.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
    • 方案 二

      请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: 1 mg/mL (2.61 mM); 悬浊液; 超声助溶

      此方案可获得 1 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

      1 mL 工作液为例,取 100 μL 10.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

      20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

    Animal Administration
    [1]

    Mice[1]
    PTEN-null U-87 MG/M human glioblastoma cancer cells are cultured in RPMI 1640 media plus 1% L-glutamine with 10% fetal bovine serum. Cells in log-phase growth are harvested and resuspended in HBSS:Matrigel (1:1, v:v) for injection into female NCr nude mice aged 20 weeks. Animals receive five million cells subcutaneously in the right lateral thorax in 0.1 mL. Mice bearing established tumors in the range of 200-500 mm3 are separated into groups of equally sized tumors (n=6-7/group) to receive escalating doses of Paxalisib. Paxalisib is formulated once weekly in 0.5% methylcellulose and 0.2% Tween-80 at concentrations needed for target doses in a volume of 0.2 mL. All formulations are stored in a refrigerator and brought to room temperature and mixed well by vortex before oral administration by gavage once daily for 23 days. Tumor volumes are calculated. Changes in body weights are reported as a percentage change from the starting weight.

    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.
