| 应用 |
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. |
| 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. |
| 备注 |
此产品所配溶液37°C只能保存3天，因此其储存溶液必须2-8°C保存. 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. |
