产品介绍


Cephalothin AI Summary
Cephalothin exhibits broad-spectrum antimicrobial activity against numerous bacterial strains, including Staphylococcus aureus, Streptococcus pneumoniae, Klebsiella pneumoniae, and Escherichia coli, among others, with varying minimum inhibitory concentrations (MIC). It is especially potent against strains such as penicillin-resistant Staphylococcus aureus and Streptococcus pyogenes, with MIC values as low as 0.015 ug/mL. The compound also shows varying degrees of efficacy against beta-lactamase-producing bacteria, with specific kinetic values (Kcat and Km) and favorable Kcat/Km ratios indicating efficient inhibition of these enzymes. Additionally, it exhibits significant bioactivity as a beta-lactamase inhibitor, with Ki values against specific enzymes like AmpC beta-lactamase being as low as 320.0 nM. Cephalothin also demonstrates modest antiviral activity against SARS-CoV-2, inhibiting virus-induced cytotoxicity at a concentration of 10 µM. However, it has limited efficacy against certain drug-resistant strains and shows moderate hepatotoxicity in clinical trials. Its solubility in water and rapid clearance rates suggest favorable pharmacokinetic properties, although its distribution throughout the body is limited. Overall, Cephalothin holds potential for further development as an antibiotic and beta-lactamase inhibitor, though considerations for toxicity and selectivity against resistant strains remain crucial..

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法:
比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL, 一共给药动物10只,您使用的配方为 10% DMSO + 40% PEG300 + 5% Tween 80 + 45% Saline / PBS / ddH2O, 那么您的工作液浓度为2 mg/mL
母液配置方法:2 mg 药物溶于 100 μL DMSO ( 母液浓度为 20 mg/mL ), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:100 μL DMSO 母液, 添加 400 μL PEG300 混匀澄清, 再加 50 μL Tween 80, 混匀澄清, 再加 450 μL Saline / PBS / ddH2O 混匀澄清
以上为“体内实验配液计算器”的使用方法举例,并不是具体某个化合物的推荐配制方式,请根据您的实验动物和给药方式选择适当的溶解方案。
