产品详情
Methotrexate-d3 是 Methotrexate 的氘代物。Methotrexate (Amethopterin) 是一种抗代谢 (antimetabolite) 和抗叶酸剂 (antifolate),可抑制二氢叶酸还原酶,从而防止叶酸转化为四氢叶酸并抑制 DNA 合成。Methotrexate也是一种免疫抑制剂和抗肿瘤剂,用于类风湿关节炎和研究多种癌症 (如急性淋巴细胞白血病)。
生物活性
Methotrexate-d 3 (Amethopterin-d3) is the deuterium labeled Methotrexate. Methotrexate (Amethopterin), an antimetabolite and antifolate agent, inhibits the enzyme dihydrofolate reductase, thereby preventing the conversion of folic acid into tetrahydrofolate, and inhibiting DNA synthesis. Methotrexate, also an immunosuppressant and antineoplastic agent, is used for the research of rheumatoid arthritis and a number of different cancers (such as acute lymphoblastic leukemia)[1][2][3].

Solid
体外研究(In Vitro)
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs. has not independently confirmed the accuracy of these methods. They are for reference only.
运输条件

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。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
