生物活性

5-Chloro-2'-deoxyuridine, a thymine analog, is to study the potential of hypochlorous acid damage to DNA and DNA precursors.

体外研究
(In Vitro)

When 5-Chloro-2’-deoxyuridine (ClDU) is placed into tissue culture medium, mammalian cells incorporate the analog into DNA. It is observed that 10 μM concentration of 5-Chloro-2’-deoxyuridine in the media does not alter cell division kinetics. Previously it has been shown that 5-Chloro-2’-deoxyuridine is metabolized and incorporated into DNA using antibodies that bind selectively to DNA containing halogenated bases. In the studies reported here, 5-Chloro-2’-deoxyuridine is more similar to BrdU in acting as a T analog. The toxicity of 5-Chloro-2’-deoxyuridine could in part be attributed to inhibition of thymidylate synthase[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: ≥ 2.08 mg/mL (7.92 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 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: ≥ 2.08 mg/mL (7.92 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 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。

Cell Assay

Human erythroleukemia K-562 cells are used throughout the study. Cells are initially seeded at 1.0×105 cells/mL and treated with either 10 μM 5-Chloro-2’-deoxyuridine or 10 μM thymidine (negative control) for 63 h, or two cell doublings. Cells are counted by trypan blue exclusion, pelleted by centrifugation (500×g) and washed with 10 mL sterile PBS[1].

Animal Administration
[2]

Rats[2]
Adult, male Wistar rats, weighing 200-250 g are used. Firstly, the animals are allowed to self-administer methamphetamine at a dose of 0.05 mg/kg/injection under a fixed-ratio 1 (FR1) schedule for baseline sessions. After that, the rats are divided into four groups. Two groups of rats (long-access; LgA-4 days (d), LgA-13 d; n=7 per group) are allowed to self-administer 0.05 mg/kg/injection of methamphetamine for 6 h per day, whereas the other groups (short-access; ShA-4 d, ShA-13 d; n=7 per group) are allowed to do so for 1 h per day. All procedures are performed during the dark cycle. On day 5, ShA-4 d and LgA-4 d rats receive one injection of 50 mg/kg 5-chloro-2’-deoxyuridine and survive for 30 min. On day 14, ShA-13 d and LgA-13 d receive one injection of 50 mg/kg 5-Iodo-2’-deoxyuridine followed by 50 mg/kg 5-chloro-2’-deoxyuridine 2 h later. These rats also survive for 30 min after the 5-Chloro-2'-deoxyuridine injection. A parallel group of drug-naive rats (n=6) receive one injection of 50 mg/kg IdU followed by 50 mg/kg 5-Chloro-2'-deoxyuridine 2 h later. These rats also survive for 30 min after the 5-Chloro-2'-deoxyuridine injection[2].

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.
