Merck, O4636, Oxytetracycline dihydrate

General description
Chemical structure: tetracycline
Application
Oxytetracycline is a tetracycline analog isolated from the actinomycete Streptomyces rimosus. It is used in studies on the oxytetracycline-resistance gene (otrA) and is used for fluorescence measurements of hepatocytes.
Biochem/physiol Actions
Antibiotic produced by Streptomyces rimosus.
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.
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, inhibiting protein synthesis (elongation). 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.
Analysis Note
solubility very slightly solube in water, it dissolves in dilute acid and alkaline solutions
