IC50 & Target[1][2]

β-lactam

 

体外研究(In Vitro)

Moxalactam (Latamoxef) inhibits 90% of strains of Escherichia coli, Klebsiella species, Proteus species, Morganella morganii, Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae and Salmonella species, including strains which are resistant to Cephalothin (HY-B1275A) and Gentamicin (HY-A0276A) at concentrations of less than 1 μg/mL.
Moxalactam exhibits moderate activity against P. aeruginosa and is usually active against other species of Pseudomonas, Acinetobacter species are usually resistant to Moxalactam.
Moxalactam has marked stability 体外研究 against a variety of β-lactamases, including that produced by B. fragilis, inhibits production of β-lactamases and does not induce class I β-lactamase.

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。
