生物活性

Nitecapone (OR-462) is an orally active and short-acting catechol-O-methyltransferase (COMT) inhibitor with gastroprotective and antioxidant properties. Nitecapone (OR-462) scavenges reactive oxygen and nitric radicals and prevents lipid peroxidation.

性状

Solid

体外研究(In Vitro)

Nitecapone (1-100 μM) reducesd GSH (reduced glutathione) depletion induced by ROOby 11-38% and oxidation to oxidized glutathione (GSSG) by 32-45%.

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

体内研究(In Vivo)

Nitecapone (30 mg/kg, ip daily for 13 days) reduces development and symptoms of neuropathic pain after spinal nerve ligation in rats.

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

Animal Model: Eighty-six male Wistar rats, weighing 140-350 g.
Dosage: 30 mg/kg (3.3 mL/kg).
Administration: IP, once daily for 13 days.
Result: Selectively and specifically inhibits COMT in the peripheral tissues, and to some extent in the CNS for ca. 3 h.
Increased the thresholds for the mechanical stimuli and thus reduced mechanical allodynia.
Reduced the number of positive reactions of the ipsilateral paws when compared with the baselines in the nitecapone-pretreated rats.
运输条件

Room temperature or refrigerated transportation.

产品不同,其溶解度不同。建议根据产品选择合适的溶剂配制储备溶液;配成溶液后,建议分装保存,避免反复冻融造成的产品失效
储备液的保存方式和期限:-80°C, 6 months; -20°C, 1 month。-80°C 储存时,建议在 6 个月内使用,-20°C 储存时,建议在 1 个月内使用。

体内研究:

建议根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都建议先按照 体外研究 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

    建议依照次序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% saline

    Solubility: ≥ 2.08 mg/mL (7.84 mM); Clear solution

    此方案可获得 ≥ 2.08 mg/mL (7.84 mM,饱和度未知) 的澄清溶液。

    以 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;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
