描述

别名 红霉素 ;红霉素碱;(-)-Erythromycin ;Abomacetin
产品介绍 Erythromycin is a potent macrolide inhibitor of CYP3A4 with antiinflammatory and prokinetic properties. Macrolides belong to a group of antibiotics that bind to the 50S ribosomal subunit and inhibit protein synthesis. Erythromycin is derived from Streptomyces erythreus and has been shown to inhibit NF-κB transcriptional activation, which leads to the inhibition of cytokine gene expression of IL-8 and lL-6. This mechanism was shown to occur via calcineruin-independent signaling T lymphocytes.
用途 A macrolide antibiotic protein synthesis inhibitor.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.
生化机理 在转肽步骤抑制延长期，靠结合到核糖体上抑制细菌蛋白合成，对细菌诱发红霉素抗性。抗菌谱: 革兰氏阴性和阳性细菌。属大环内酯抗生素（Macrolide antibiotic）
