説明

Bacitracin is a mixture of similar peptides produced by fermentation of the bacterium Bacillus subtil is. The A-type component predominates. Its mode of action is to inhibit both peptidoglycan biosynthesis at a late stage (probably at the dephosphorylation of the phospholipid carrier step) and disruptions of plasma membrane function.

化学的特性

White to pale buff powder

化学的特性

Bacitracin is a white to light tan powder which is odorless or having a slight odor and very bitter taste.

Originator

Baciguent,Upjohn,US,1948

使用

antibiotic agent effective against gram-positive organisms and spirochetes; in products for topieal treatment, ear medications and ophthalmie drugs

使用

Polypeptide antibacterial.

使用

Bacitracin is a peptide antibiotic effective against gram-postive bacteria. Bacitracin is an inhibitor of peptidoglycan synthesis. Bacitracin disrupts bacterial cell wall synthesis by inhibiting depho sphorylation of lipid pyrophosphate. Bacitracin also strongly inhibits proline endopeptidase from human muscle.

定義

A complex of cyclic peptide antibiotic of known chemical structure isolated from the Tracy-I strain of Bacillus subtilis.

適応症

This polypeptide antibiotic, which is produced from Bacillus subtilis, interferes with bacterial cell wall growth and is bactericidal against many grampositive organisms such as streptococci, staphylococci, and pneumococci but is inactive against most gram-negative organisms. All anaerobic cocci, Neisseria, and the tetanus and diphtheria bacilli are also sensitive to bacitracin.
Resistance is rare, but some staphylococcal strains are inherently resistant. Hypersensitivity reactions are uncommon. Bacitracin is stable in petrolatum (but not water-miscible preparations) and is available as an ointment or as a component of antibiotic mixtures. Sensitization to bacitracin has been reported more recently, particularly in patients with leg ulcers.

Manufacturing Process

The early patent, US Patent 2,498,165 first disclosed bacitracin and described a process for preparing bacitracin, comprising cultivating Bacillus subtilis Tracy I in a nutritive medium, at substantially pH 7 and 37°C, for more than three days, extracting the antibiotic from the resulting medium with a low molecular weight alcohol, concentrating the resulting alcoholic solution in vacuo, acidifying the resulting concentrate, extracting the antibiotic from the resulting solution, and precipitating the antibiotic from the resulting solution, with a precipitating agent for the antibiotic, selected from the group consisting of Reinecke's salt, phosphotungstic acid, phosphomolybdic acid, molybdic acid, picric acid, ammonium rhodanilate, and azobenzene-p-sulfonicacid.
A subsequent patent, US Patent 2,828,246 described a commercial process for bacitracin production. A 1,230 gallon portion of a medium containing 10% soybean oil meal, 2.50% starch and 0.50% calcium carbonate having a pH of 7.0 was inoculated with a culture of bacitracin-producing bacteria of the Bacillus subtilis group and the inoculated medium incubated for a period of 24 hours with aeration such that the superficial air velocity was 12.1. An assay of the nutrient medium following the fermentation revealed a yield of bacitracin amounting to 323 units/ml. This was more than twice the yields previously obtained.
Then, a patent, US Patent 2,834,711 described the purification of bacitracin. In this process for purifying bacitracin, the steps comprise adding a watersoluble zinc salt to a partially purified aqueous solution of bacitracin, adjusting the pH to from 5 to 9, recovering the precipitate which forms, dissolving the precipitate in water at a pH not substantially in excess of 4, and removing the zinc ion by passing the aqueous solution through a cation exchange resin and drying the resulting solution to obtain dry solid bacitracin.
Another patent, US Patent 2,915,432describes a process of recovering and concentrating bacitracin from aqueous filtered fermentation broth containing on the order of 3% protein-aceous solids which comprises intimately contacting the broth with a synthetic organic cation exchange resin having as its functional groups nuclear sulfonic acids and having a crosslinkage of the order of 1 to 2%, with the resin being in the hydrogen form, and eluting the adsorbed bacitracin from the resin with a weak base.
Bacitracin recovery is described in US Patents 3,795,663 and 4,101,539.

Antibacterial

一般的な説明

The organism from which Johnson et al. produced bacitracinin 1945 is a strain of B. subtilis. The organism hadbeen isolated from debrided tissue from a compound fracturein 7-year-old Margaret Tracy, hence the name “bacitracin.”Bacitracin is now produced from the licheniformisgroup (B. subtilis). Like tyrothricin, the first useful antibioticobtained from bacterial cultures, bacitracin is a complex mixture of polypeptides. So far, at least 10 polypeptideshave been isolated by countercurrent distribution techniques:A, A1, B, C, D, E, F1, F2, F3, and G. The commercialproduct known as bacitracin is a mixture of principallyA, with smaller amounts of B, D, E, and F1–3.The official product is a white to pale buff powder that isodorless or nearly so.
The activity of bacitracin is measured in units per milligram.The potency per milligram is not less than40 units/mg except for material prepared for parenteral use,which has a potency of not less than 50 units/mg. It is a bactericidalantibiotic that is active against a wide variety ofGram-positive organisms, very few Gram-negative organisms,and some others. It is believed to exert its bactericidaleffect through inhibition of mucopeptide cell wall synthesis.Its action is enhanced by zinc. Although bacitracin hasfound its widest use in topical preparations for local infections,it is quite effective in several systemic and local infectionswhen administered parenterally. It is not absorbedfrom the GI tract; accordingly, oral administration is withouteffect, except for the treatment of amebic infectionswithin the alimentary canal.

危険性

Poison; moderately toxic; mutagen.

応用例(製薬)

A mixture of peptides produced by Bacillus licheniformis. Bacitracin A is the major constituent of commercial preparations. The more stable zinc salt is used in topical formulations. It has been widely used as a growth promoter in animals, but has been banned for that purpose in the European Union.
It is highly active against many Gram-positive bacteria and is mainly used as a component of topical preparations. Although strains of Staph. aureus are usually susceptible, they are rather less so than most other Gram-positive bacteria. Streptococcus pyogenes is so much more susceptible than other hemolytic streptococci that bacitracin susceptibility is used as a screening test for identification. Clostridium difficile and Actinomyces spp. are susceptible, but enterobacteria and Pseudomonas spp. are resistant. Entamoeba histolytica is inhibited by 0.6–10 mg/L.
Resistance is uncommon, but has been detected in Staph. aureus following topical treatment.
It is nephrotoxic and unsuitable for parenteral use. Systemic toxicity from application to skin or ulcerated areas is rare, but it may cause allergic reactions and occasional anaphylaxis has been described. It is found in many ointments and ophthalmic preparations, usually together with other components, including polymyxins, neomycin and corticosteroids.
Bacitracin is not absorbed by mouth but oral preparations have been used for suppression of gut flora, including C. difficile.

臨床応用

Bacitracin is predominantly active against Gram-positive microorganisms, and parenteral use is limited to IM injection for infants with pneumonia and empyema caused by staphylococci resistant to other agents. It is rather neuro- and nephrotoxic and, therefore, is used in this manner with caution. Bacitracin also is widely employed topically to prevent infection in minor cuts, scrapes, and burns.

安全性プロファイル

A poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion and subcutaneous routes. Mutation data reported.

職業ばく露

Bacitracin is used as an ingredient in antibiotic ointments to treat or prevent topical or eye infections. Commercial Bacitracin is a mixture of at least 9 bacitracins. Also used as a feed and drinking water additive for animals; as a food additive for human consumption.

輸送方法

UN 3249 Medicine, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials.

純化方法

Bacitracin has been purified by carrier displacement using n-heptanol, n-octanol and n-nonanol as carriers and 50% EtOH in 0.1 N HCl. The pure material gives one spot with RF ~0.5 on paper chromatography using AcOH:n-BuOH:H2O (4:1:5). [Porath Acta Chem Scand 6 1237 1952.] It has also been purified by ion-exchange chromatography. It is a white powder soluble in H2O and EtOH but insoluble in Et2O, CHCl3 and Me2CO. It is stable in acidic solution but unstable in base. It is a strong antibacterial. [Abraham & Bewton Biochem J 47 257 1950, Synthesis: Munekata et al. Bull Chem Soc Jpn 46 3187, 3835 1973, Beilstein 27 III/IV 5746.]
