Description and Uses
Chlortetracycline was found in the culture broth of Streptomyces aureofaciens by Duggar et al. of Lederle Laboratories in 1948 and named aureomycin. It shows a wider range of antibiotic activity than the earlier antibiotics, penicillins, and streptomycins and as great as that of chloramphenicol. Its activity covers grampositive and gram-negative bacteria as well as Rickettsia and Chlamydiae. Chlortetracycline has been replaced by other tetracyclines in clinical use and is used now used as a feed additive to promote the growth of livestock.
Chlortetracycline hydrochloride is a salt prepared from chlortetracycline taking advantage of the basic dimethylamino group which protonates and readily forms the salt in hydrochloric acid solutions. The hydrochloride is the preferred formulation for pharmaceutical applications. Like all tetracyclines, chlortetracycline shows broad spectrum antibacterial and antiprotozoan activity and acts by binding to the 30S and 50S ribosomal sub-units, blocking protein synthesis.
