产品描述 |
一种α-Glucosidase抑制剂 |
|
靶点 |
IC50: 2.1μM (α-Glucosidase) Ki: 0.578μM (α-Glucosidase) |
|
体外研究 |
In in vitro α-Glucosidase assays, Ceftezole is shown to be a reversible, non-competitive inhibitor of yeast α-glucosidase with a Ki value of 5.78×10-7 M when the enzyme mixture is pretreated with ceftezole |
|
体内研究 |
Using an in vivo streptozotocin-induced mouse model, blood glucose levels are confirmed to be decreased by 30% 20 min after Ceftezole treatment (10mg/kg/day). Expression levels of glycogen synthase kinase-3, peroxisome proliferatoractivated receptor-γ, and uncoupling protein-3 mRNA are also slightly decreased compare to controls following Ceftezole treatment |
推荐实验方法(仅供参考)
|
Kinase Assay |
Ceftezole at the designated concentrations is added to the enzyme buffer solution and incubated at 30˚C for 1 h, and the substrate is then added to start the enzyme reaction. When pretreatment is not specified, mixtures of substrate and Ceftezole at various concentrations are prepared beforehand and added to the enzyme solution. Enzyme reactions are performed at 30˚C for 30 min, and 3 vol of 1 M sodium carbonate are then added to stop the reaction. The total reaction volume is 100μL. Enzymatic activity is quantified by measuring the absorbency at 405nm |

Animal Administration |
Diabetes is induced by intravenous STZ injections [30mg/kg in fresh 10mM sodium citrate buffer (pH 4.5)] into veins of mice in one diabetic control group and one treatment group. Diabetic female mice are identified as those having blood glucose levels >250mg/dL using a kit. Ceftezole or vehicle (distilled water) is given intraperitoneally (30mg/kg/day) every day for 14 days. Twenty-four hours after the final Ceftezole treatment, mice are anesthetized with pure diethylether inhalation, and blood analysis is carried out |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为:C1V1 = C2V2 ( 输入 输出 )
母液,添加 300 μLPEG300
混匀澄清,再加 50μLTween80, 混匀澄清,再加 600μLSaline/PBS/ddH2O
混匀澄清方案所需的各种助溶剂如: DMSO , PEG300 / PEG400 , Tween 80 , SBE-β-CD , 玉米油 等, 均可点击跳转或在网站搜索购买。
计算结果:
工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL Saline/PBS/ddH2O,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
