Flumethasone 是皮质类固醇,可局部用药。它可与 Clioquinol 联合使用,研究外耳炎和耳真菌病。它作用于动物模型时,抗炎活性比 Cortisone 高 420 倍。
产品描述
Flumethasone is a glucocorticoid receptor agonist, with anti-inflammatory, antipruritic and vasoconstrictive properties.
体外活性
在患酮症的小牛中,Flumethasone(5 mg )能够增加血浆葡萄糖浓度,降低血清β-羟基丁酸和尿乙酰乙酸浓度,同时能够改善子宫疾病.在患严重急性支气管肺炎小牛中,Flumethasone与头孢噻呋钠联用,能够使生理指标回到正常水平,提高生存率.
激酶实验
Topoisomerase I Cleavable Complex Assay: Topoisomerase I is isolated from calf thymus and is devoid of topoisomerase II. All reactions are carried out in 10 mL volumes of reaction buffer (50 mM Tris-HCl, pH 7.5, 100 mM KCl, 0.5 mM EDTA, and 30 pg/mL BSA) in microtiter plates. Camptothecin is dissolved in DMSO at 10 mg/mL and serially diluted in 96-well microtiter plates to which the 32P end-labeled pBR322 DNA and topoisomerase enzyme are added. The reaction mixture is incubated at room temperature for 30 min and then the reaction stopped by adding 2 mL of a mixture of sodium dodecyl sulfate and proteinase K (1.6% and 0.14 mg/mL final concentrations, respectively). The plates are heated at 50 °C for 30 min, 10 mL of standard stop mixture containing 0.45 N NaOH is added in order to generate single-stranded DNA, and the samples are electrophoresed in 1.5% agarose gels in TBE buffer. Gels are blotted on nitrocellulose paper, dried, and exposed to X-ray film. The units of cleavage are calculated from the autoradiographs and plotted against the log drug concentration. The IC50 values are then obtaine
