Dalfopristin (mesylate) is a streptogramin antibiotic and a 50S ribosome inhibitor. Streptogramins are produced by a variety of Streptomyces sp as a mixture (ratio of 7:3) of two chemically unrelated compounds, type A and B. Dalfopristin, the type A Streptogramin is often combined with type B streptogramin antibiotic, quinupristin, to produce Quinupristin-Dalfopristin Complex, known commercially as Synercid. The ribosome is composed of two ribonucleoprotein subunits, the 50S, and 30S. The 50S ribosome inhibitors inhibited protein synthesis.

体外活性 | Dalfopristin is a cyclic polyunsaturated macrolactone that interferes with the binding of tRNA substrates to both A- and P-sites [2]. Dalfopristin blocked the access of peptidyl-tRNAs to the ribosome and peptidyltransferase elongation reaction in bacteria [1]. quinupristin and dalfopristin acted synergistically to kill Gram-positive bacteria, as well as some Gram-negative and anaerobic bacteria [2][3]. Dalfopristin hydrolyzed rapidly to virginiamycin M under physiological conditions. |

对于不同动物的给药剂量换算,您也可以参考 更多...
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5% DMSO+30% PEG300+5% Tween 80+60% 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 50 μL DMSO (母液浓度为 40 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:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
