Properties: light yellow or yellow powder soluble in water, slightly soluble in ethanol insoluble in methanol, chloroform, ethyl acetate and other organic solvents, stable aqueous solution antibiotic activity stability: Storage at room temperature for two years without causing degradation, light will not cause significant reduction in biological potency; 120 ℃ temperature four hours does not cause biological potency reduced; there hygroscopic, but a dry and do not cause changes in the biological potency of apramycin 1967 a new family of broad-spectrum antibiotic mixture discovery, scientists from the fermentation broth of bacteria isolated were six kinds of components, and component 2 named apramycin (Apramycin). apramycin (Apramycin) is a cyclic amino alcohols antibiotic produced by Streptomyces black (Strepomycos tenebrarius) produced, its natural state as the free base
Use: Biochemical studies interfere with bacterial protein synthesis in prokaryotes specifically interfere with the synthesis of ribosomal proteins and inhibit harmful bacteria in animals, against Gram-positive bacteria, some Gram-negative bacteria are effective part of Mycoplasma also effective... . The most sensitive is E. coli, Salmonella, Staphylococcus aureus, mycoplasma, etc. Escherichia coli and Salmonella bactericidal capacity even stronger than the antibacterial ability.
