产品详情
Avibactam sodium (NXL-104) hydrate 是一种共价的、可逆的非 β-内酰胺 β-内酰胺酶抑制剂 (β-lactamase) 抑制剂,抑制 β-lactamase TEM-1 和 CTX-M-15,IC50 分别为 8 nM 和 5 nM。
生物活性
Avibactam sodium (NXL-104) hydrate is a covalent and reversible non-β-lactam β-lactamase inhibitor which inhibits β-lactamase TEM-1 and CTX-M-15 with IC 50 s of 8 nM and 5 nM, respectively.
性状
Solid
IC50 & Target[1][2]
IC50: 5 nM (CTX-M-15), 8 nM (TEM-1)
体外研究(In Vitro)
Avibactam is a molecule with little antibacterial activity, that inhibits class A and C β-lactamases, but not metallo types and Acinetobacter OXA carbapenemases.
Ceftazidime (HY-B0593)-Avibactam (0-256 mg/L) inhibits 16 bla KPC-2 positive and 1 of bla OXA-232 positive Klebsiella pneumonia growth with MIC50 and MIC90 for both 8?mg/L. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Ceftazidime-Avibactam (0.375?mg/g; s.c.; q8h for 10 days) has a significant effect on the bacteria and led to a certain therapeutic efficacy in K. pneumoniae strain Y8 infected mouse model.
Avibactam (64 mg/kg; s.c.; once) shows mean estimated half-life in plasma in the terminal phase of 0.24 h in Pseudomonas aeruginosa infected neutropenic mice with lung infection. has not independently confirmed the accuracy of these methods. They are for reference only.

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
