其他信息
Donepezil Hydrochloride is the hydrochloride salt of a piperidine derivative with neurocognitive-enhancing activity. Donepezil reversibly inhibits acetylcholinesterase, thereby blocking the hydrolysis of the neurotransmitter acetylcholine and, consequently, increasing its activity. This agent may improve neurocognitive function in Alzheimer's disease, reduce sedation associated with opioid treatment of cancer pain, and improve neurocognitive function in patients who have received radiation therapy for primary brain tumors or brain metastases.
An indan and piperidine derivative that acts as a selective and reversible inhibitor of ACETYLCHOLINESTERASE. Donepezil is highly selective for the central nervous system and is used in the management of mild to moderate DEMENTIA in ALZHEIMER DISEASE.

请根据您的实验动物和给药方式选择适当的溶解配方/方案:
1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL;

3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果,工作液请现配现用!
6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们;

5 mM 0.4808 mL 2.4038 mL 4.8077 mL
10 mM 0.2404 mL 1.2019 mL 2.4038 mL

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;

2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;

3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);

4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。

计算器

摩尔浓度计算器可计算特定溶液所需的质量、体积/浓度,具体如下:

  • 计算制备已知体积和浓度的溶液所需的化合物的质量
  • 计算将已知质量的化合物溶解到所需浓度所需的溶液体积
  • 计算特定体积中已知质量的化合物产生的溶液的浓度
使用摩尔浓度计算器计算摩尔浓度的示例如下所示:
假如化合物的分子量为350.26 g/mol,在5mL DMSO中制备10mM储备液所需的化合物的质量是多少?
  • 在分子量(MW)框中输入350.26
  • 在“浓度”框中输入10,然后选择正确的单位(mM)
  • 在“体积”框中输入5,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案17.513 mg出现在“质量”框中。以类似的方式,您可以计算体积和浓度。

稀释计算器可计算如何稀释已知浓度的储备液。例如,可以输入C1、C2和V2来计算V1,具体如下:

制备25毫升25μM溶液需要多少体积的10 mM储备溶液?
使用方程式C1V1=C2V2,其中C1=10mM,C2=25μM,V2=25 ml,V1未知:
  • 在C1框中输入10,然后选择正确的单位(mM)
  • 在C2框中输入25,然后选择正确的单位(μM)
  • 在V2框中输入25,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案62.5μL(0.1 ml)出现在V1框中
g/mol

分子量计算器可计算化合物的分子量 (摩尔质量)和元素组成,具体如下:

注:化学分子式大小写敏感:C12H18N3O4  c12h18n3o4
计算化合物摩尔质量(分子量)的说明:
  • 要计算化合物的分子量 (摩尔质量),请输入化学/分子式,然后单击“计算”按钮。
分子质量、分子量、摩尔质量和摩尔量的定义:
  • 分子质量(或分子量)是一种物质的一个分子的质量,用统一的原子质量单位(u)表示。(1u等于碳-12中一个原子质量的1/12)
  • 摩尔质量(摩尔重量)是一摩尔物质的质量,以g/mol表示。

配液计算器可计算将特定质量的产品配成特定浓度所需的溶剂体积 (配液体积)

  • 输入试剂的质量、所需的配液浓度以及正确的单位
  • 单击“计算”按钮
  • 答案显示在体积框中
动物体内实验配方计算器(澄清溶液)
第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶/难溶于水的化合物),不同的产品和批次配方组成不同,如对配方有疑问,可先联系我们提供正确的体内实验配方。此外,请注意这只是一个配方计算器,而不是特定产品的确切配方。

  • Relationship between brain and plasma donepezil concentrations and the pharmacological effects. Donepezil HCl (0.3–10 mg/kg free drug dissolved in saline) was administered orally for four consecutive days to the corresponding treatment groups (8 animals per group). Dose-dependent changes in plasma (A) and brain (B) concentrations of donepezil were observed 1 h after the fourth dose of donepezil HCl in mice. After oral treatment, brain donepezil levels positively correlated with plasma donepezil levels (C). Data represent the means ± SEM.[3].The Effects of Donepezil, an Acetylcholinesterase Inhibitor, on Impaired Learning and Memory in Rodents. Biomol Ther (Seoul). 2018 May 1;26(3):274-281.
  • Relationship between the brain concentration of donepezil and the pharmacological effects. Donepezil HCl (0.3–10 mg/kg free drug dissolved in saline) was administered orally for four consecutive days to the corresponding treatment groups (8 animals per group). As the concentration of donepezil in the brain increased, the recovery of spontaneous alternations (SA) also improved.
