体外研究
(In Vitro)

Citarinostat (ACY241;300 nM;24小时;A2780细胞)导致 α-微管蛋白高乙酰化增加,与微管蛋白去乙酰化酶 HDAC6 的抑制一致。Citarinostat低剂量可选择性抑制 HDAC6,而高剂量暴露可抑制 I 类 HDAC 同型酶[1]
Citarinostat 在 A2780、TOV-21G 卵巢癌和 MDA-MD-231 乳腺癌细胞中的IC50 范围为4.6 ~ 6.1 μM[1]
Citarinostat在 3 μM剂量下抑制细胞增殖,不诱导细胞凋亡,10 μM 时显著诱导细胞凋亡,完全抑制细胞增殖[1]

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

Western Blot Analysis[1]

Cell Line: A2780 cells
Concentration: 0 μM, 0.1 μM, 0.3 μM, 0.5μM, 1 μM, 3 μM
Incubation Time: 24 hours
Result: Resulted in increased hyperacetylation of α-tubulin, consistent with inhibition of the tubulin deacetylase HDAC6. In contrast, hyperacetylation of histone H3, a target of Class I HDACs, was only observed at doses above 1 μM.

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

Animal Model: Female athymic nude mice (7-week-old) injected with TOV-21G cells[1]
Dosage: 50 mg/kg
Administration: Intraperitoneal injection; once daily for five days, followed by two days off; for 3 weeks
Result: Combination treatment with NSC 125973 resulted in significantly suppression of tumor growth.

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: ≥ 2.5 mg/mL (5.34 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。
  • 方案 二

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

    Solubility: ≥ 2.5 mg/mL (5.34 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 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    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。

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.
