一般說明
Chemical structure: tetracycline
Freely soluble in water, sparingly soluble in Ethanol (96%). Solution in water becomes turbid on standing owing to the precipitation of chromatograms.
應用
Oxytetracycline is a tetracycline analog isolated from the actinomycete Streptomyces rimosus. Oxytetracycline is an antibiotic indicated for treatment of infections caused by Gram positive and Gram negative microorganisms such as Mycoplasma pneumoniae, Pasteurella pestis, Escherichia coli, Haemophilus influenzae, and Diplococcus pneumoniae. It is used in studies on the oxytetracycline-resistance gene (otrA). Oxytetracycline hydrochloride is used to study phagosome-lysosome (P-L) fusion in P388D1 cells and antibiotic susceptibilities of Mycoplasma bovis isolates.
生化／生理作用
Mode of Action: Inhibits protein synthesis (elongation) by preventing binding of aminoacyl-tRNA to the 30S subunit.
Antimicrobial spectrum: Gram-negative and Gram-positive bacteria.
Mode of Resistance: Active efflux, ribosome protection, tetracycline inactivation.
Antimicrobial spectrum: Gram-negative and Gram-positive bacteria.
Mode of Resistance: Active efflux, ribosome protection, tetracycline inactivation.
Oxytetracycline inhibits translation which results in cell death. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. The binding is reversible in nature. Oxytetracycline is lipophilic so it can easily pass through a cell membrane and passively diffuses through channels in the bacterial membrane.
