说明

红霉素是一种复杂的大环内酯类抗生素,具有抑菌活性。由于其对革兰氏阳性和少数革兰氏阴性菌株的潜在活性,它通常用于人类和兽医。
红霉素是一种抗生素,由某些红链霉菌菌株生长产生。本品主要由红霉素A和少量红霉素B和C组成,建议浓度为100 mg/L。浓度在50至200mg/L之间也被证明对控制细菌生长有效。红霉素已被用作胃动素受体激动剂,在体外阻断人气道中的呼吸糖缀合物分泌,并用于选择质粒治愈和重组乳酸乳球菌MG1363菌株。
红霉素可用作通过各种色谱技术测定药物制剂中分析物的药物参考标准。

一般描述

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Erythromycin is a complex macrolide antibiotic drug that exhibits a bacteriostatic activity. It is generally employed in human and veterinary medicines owing to its potential activity against gram positive and a few gram negative strains.
 

应用

Erythromycin is an antibiotic produced by growth of certain strains of Streptomyces erythreus. This product is composed largely of erythromycin A with small amounts of erythromycins B and C and is recommended for concentration at 100 mg/L. Concentrations between 50 and 200 mg/L have also proven effective in controlling bacterial growth. Erythromycin has been used as a motilin receptor agonist, to block respiratory glycoconjugate secretion in human airways in vitro, and for selecting plasmid-cured and recombinant lactococcus lactis MG1363 strains.
Erythromycin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
 

生化/生理作用

作用机制: 红霉素通过在转肽步骤中抑制延伸起作用,特别是通过结合细菌70S rRNA复合物的50S亚单位来抑制氨酰从A位点到P位点的易位。
抗菌谱:该产品可以抗革兰氏阴性和革兰氏阳性细菌。
 

注意

This product is stable in solution at 37°C for 3 days. Stock solutions should be stored at 2-8°C.
 

制备说明

This product is soluble in water at 2 mg/mL, with a 0.067% solution in water yielding a pH of 8.0-10.5. It is also soluble in ethanol at 50 mg/mL, yielding a clear, colorless to faint yellow solution. It is freely soluble in alcohol, acetone, chloroform, acetonitrile and ethyl acetate but forms salts with acids. All solutions should be protected from light.
