    Berzosertib purchased from MCE. Usage Cited in: Eur J Med Chem. 2017 Feb 15;127:691-702.  [Abstract]

    Relative cell viability (%) in MDCK CAIX- and CAIX+ cells exposed to ATR inhibitors (VE-821 and VE-822) or the CAIXi conjugated derivatives in combination with radiation during normoxia (21% O2) and anoxia (≤0.02% O2). Normoxic cells are irradiated with 2 Gy and anoxic cells with 4 Gy to induce similar effects on cell viability.

    生物活性

    Berzosertib (VE-822) is an ATR inhibitor with a Ki value of less than 0.2 nM. It also inhibits ATM with a Ki of 34 nM.

    IC50 & Target[1]

    ATR

    0.2 nM (Ki)

    ATM

    34 nM (Ki)

    PI3Kγ

    220 nM (Ki)

    体外研究
    (In Vitro)

    Berzosertib (VE-822) also inhibits DNK-PA, mTOR, PI3Kγ with IC50 of >4, >1, and 0.22 μM, respectively. In PSN-1 and MiaPaCa-2 cells, Berzosertib (VE-822) inhibits ATR and ATM with IC50 of 19 nM and 2.6 μM, respectively. VE-822 (80 nM) reduces phospho-Ser345-Chk1 after NSC 613327 (100 nM), radiation (XRT) (6 Gy) or both in PDAC. Additionally, Berzosertib (VE-822) does not inhibit ATM, Chk2 or DNA-PK phosphorylation in response to radiation, which further supports the selectivity of Berzosertib (VE-822) for ATR. VE-822 decreases survival of irradiated PDAC (all lines used are p53-mutant; K-Ras mutant). Knock down of Chk1 by siRNA sensitizes PSN-1 and MiaPaCa-2 cells to radiation but the radiosensitising effect is less profound compare with Berzosertib (VE-822). Adding Berzosertib (VE-822) to NSC 613327 reduces survival ~2-3-fold and dramatically more after chemoradiotherapy[1].

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

    体内研究
    (In Vivo)

    PSN-1 xenografts are treated with Berzosertib (VE-822) (60 mk/kg; d0, 1), NSC 613327 (100 mg/kg; d0) and/or XRT (6 Gy; d1). Tumors are then harvested 2 h post-XRT. Berzosertib (VE-822) inhibits p-Ser-345-Chk1 in xenografts after DNA-damaging agents, establishing VE-822 as a potent inhibitor of ATR in vivo. Besides, Berzosertib (VE-822) enhances the therapeutic efficacy of radiation (XRT) in MiaPaCa-2 and PSN-1 xenograft models[1].

    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% Vitamin E d-alpha tocopheryl polyethylene glycol 1000 succinate

      Solubility: 9.38 mg/mL (20.24 mM); 悬浊液; 超声助溶

    • 方案 二

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

      Solubility: ≥ 2.5 mg/mL (5.39 mM); 澄清溶液

      此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 25.0 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。

    Cell Assay
    [1]

    NSC 613327 (10 nM) is added 24 h pre-XRT and is replaced with fresh medium before addition of Berzosertib (VE-822). PSN-1 cells are treated with Berzosertib (VE-822) (80 nM) for 1 h before, through to 18 h after, XRT (6 Gy). Apoptosis is analyzed 48 h after XRT by flow cytometry using an Annexin V-FITC kit with PI[1].

    Animal Administration
    [1]

    Mice[1]
    MiaPaCa-2 cells and PSN-1 cells (106 in 50 μL serum-free medium mixed with 50 μL of Matrigel) are inoculated subcutaneously in female Balb/c nude mice. When the xenograft tumors reach 80 mm3, the mice are randomized. Berzosertib (VE-822) (60 mg/kg) is administered by oral gavage on one of three alternate schedules; either daily on days 0-5 (total of six days dosing), daily on days 0 through to 3 (total of 4 days dosing) or on days 1, 3 and 5. XRT (6 Gy) is given either on days 0 or 1 or days 1-5 (total of 5 days dosing; 2 Gy). NSC 613327 is dosed at 100 mg/kg by intraperitoneal injection on day 0. XRT to the tumor is given 2 h after initiation of Berzosertib (VE-822) treatment.

    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.
