• 説明

  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 Chlortetracycline has been replaced by other tetracyclines in clinical use and is used now used as a feed additive to promote the growth of livestock.

• 化学的特性

  Yellow Solid

• 使用

  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.

• 一般的な説明

  Chlortetracycline (Aureomycin hydrochloride) was isolatedby Duggar in 1948 from S. aureofaciens. This compound,which was produced in an extensive search for new antibiotics,was the first of the group of highly successful tetracyclines.It soon became established as a valuable antibioticwith broad-spectrum activities.
  It is used in medicine chiefly as the acid salt of the compoundwhose systematic chemical designation is 7-chloro-4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,6,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-2-naphthacenecarboxamide.The hydrochloride salt is a crystallinepowder with a bright yellow color, which suggested itsbrand name, Aureomycin. It is stable in air but slightly photosensitiveand should be protected from light. It is odorlessand bitter. One gram of the hydrochloride salt will dissolvein about 75 mL of water, producing a pH of about 3. It isonly slightly soluble in alcohol and practically insoluble inother organic solvents.
  Oral and parenteral forms of chlortetracycline are nolonger used because of the poor bioavailability and inferiorpharmacokinetic properties of the drug. It is still marketed inointment forms for topical and ophthalmic use.

• 合成

  The compound is produced via shaking culture of Actinomyces strains, such as No. 525-V 4-25 and No. 525-D 29, with production levels reaching up to 5700 mcg/ml at pH 6.8 after 5 days; rapid consumption of ionic chlorine occurs during the phase of rapid growth and rising production. Isolation involves extracting the antibiotic from culture broth using butanol or aqueous hydrochloric acid, followed by recrystallization from water after adding hydrochloric acid and cooling, yielding crystalline chlortetracycline hydrochloride with yields ranging from 38.21% to 66.42%[1].

• 純化方法

  Purify the salt by dissolving 1g rapidly in 20mL of hot water, cooling rapidly to 40o, treating with 0.1mL of 2M HCl, and chilling in an ice-bath. The process is repeated twice. It is also recrystallised from Me2NCHO/Me2CO. [Stephens et al. J Am Chem Soc 76 3568 1954, UV: McCormick et al. J Am Chem Soc 79 2849 1975, Beilstein 14 IV 2631.]
