용도

Chlortetracycline was the first reported member of the tetracycline class, isolated from Streptomyces aureofaciens in 1948. Chlortetracyclines heralded the early wave of antibiotic discoveries from microbes and after 50 years are still widely used as pharmaceuticals. Chlortetracycline is a pigment and, like most pigments, is extremely sensitive to environmental and storage conditions. Commercial chlortetracycline may contain significant levels of degradation products.

Indications

Chlorotetracycline, an antibiotic with a broad spectrum of action, causes a bacteriostatic effect with respect to Gram-positive (staphylococci, including those that produce penicillinase; streptococci, pneumococci; clostridia, listeria, and anthrax bacillus) and Gram-negative microorganisms (gonococci, whooping cough bacillus, colon bacillus, enterobacteria, klebisella, salmonella, shigella), as well as Rickettsia, chlamydia, mycoplasma, and spirochaeta. Blue-pus bacillus, proteus, serracia, most strains of Bacteroides fragilis, most fungi, and small viruses are resistant to this drug. It is used for pneumonia, bronchitis, empyema of the lungs, angina, cholecystitis, whooping cough, endocarditis, endometritis, intestinal infections, prostatitis, syphilis, gonorrhea, brucellosis, osteomyelitis, purulent infections of soft tissues, and others caused by microorganisms sensitive to this drug. Synonyms of this drug are aureomycin, biomycin, xanthomycin, and others.

정의

ChEBI: A member of the class of tetracyclines with formula C22H23ClN2O8 isolated from Streptomyces aureofaciens.

Antimicrobial activity

It is slightly less active than tetracycline against many bacteria, with the exception of Gram-positive organisms.

Pharmaceutical Applications

7-Chlortetracycline. A fermentation product of certain strains of Streptomyces aureofaciens. Formulated as the hydrochloride or the free base for oral or topical application.

Pharmacokinetics

Oral absorption：30–60%
C_max 500 mg oral：2.5–7 mg/L：
Plasma half-life： 5–6 h
Volume of distribution： c.2 L/kg
Plasma protein binding： 47–65%
Absorption is relatively poor compared with other tetracyclines. It undergoes rapid metabolism and is largely eliminated by biliary excretion, with only a small proportion eliminated via the kidney. Despite this, chlortetracycline is not recommended for patients in renal failure, since accumulation occurs as a consequence of the half-life increase to approximately 7–11 h.

Clinical Use

Its uses are those common to the group. It has also been used topically in the management of recurrent aphthous ulcers of the mouth, but experience is limited and the mechanism of action is unknown.

부작용

Side effects are typical of the group. Contact hypersensitivity has been reported with topical application to abraded skin and varicose ulcers.

Safety Profile

Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of Cland NOx. See also TETRACYCLINE.

Purification Methods

Aureomycin is dehydrated by azeotropic distillation of its solution with toluene. On cooling, the anhydrous material crystallises out and is recrystallised from *C6H6, then dried under vacuum at 100o over paraffin wax. (If it is crystallised from MeOH, it contains MeOH which is not removed on drying.) [Stephens et al. J Am Chem Soc 76 3568 1954, Laskin & Chan Biochem Biophys Res Commun 14 137 1964].
