产品详情
Methotrexate α-tert-butyl ester,经 OtBu 修饰,显著降低 HT1080 荷瘤小鼠的肿瘤生长。Methotrexate 是一种抗代谢和抗叶叶酸剂,也是一种免疫抑制剂和抗肿瘤药物。
生物活性
Methotrexate α-tert-butyl ester, capped by OtBu, significantly reduces tumor growth in HT1080 tumor bearing mice. Methotrexate is an antimetabolite and antifolate agent and is also an immunosuppressant and antineoplastic agent.
性状
Solid
体外研究(In Vitro)
OtBu-MTX-PVG is less HT1080 than MTX-PVG against HT1080 cells. It shows that protection of the α-carboxyl group of MTX results in reduced in vitro activity. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Lys-MTXcleavable- (OtBu) significantly reduces tumor growth in HT1080 tumor bearing mice.
The protection of the α-carboxyl group of methotrexate may be used to improve the circulatory half-life and reduce the liver accumulation of similar MTX-conjugated dendrimers, while still retaining antitumor activity in vivo. 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
