Opis

Opis ogólny

Chemical structure: macrolide

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.

Zastosowanie

Erythromycin has been used:

• as a supplement for nutrient broth medium for culturing green fluorescent protein (GFP)- expressing E. coli[1]
• as a model drug to determine small intestinal (SMI) microtissue viability using the MTT assay{254
• as an antibiotic to study the treatment strategies of chronic infections[2]

Działania biochem./fizjol.

Mode of Action: Erythromycin acts by inhibiting elongation at the transpeptidation step, specifically aminoacyl translocation from the A-site to P-site by binding to the 50s subunit of the bacterial 70s rRNA complex.

Antimicrobial Spectrum: This product acts against both gram-negative and gram-positive bacteria.

Przestroga

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

Uwaga dotycząca przygotowania

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.
