• Beschreibung

  Sulfamethazine is an antibacterial sulfonamide. Like other sulfonamides, sulfamethazine is bacteriostatic, competitively inhibiting dihydropteroate synthase to block folate synthesis and inhibit growth and multiplication. Sulfamethazine is metabolized by cytochrome P450 isoforms and arylamine N-acetyltransferase 2 in a sex-dependent manner.

• Originator

• Verwenden

  Sulfamethazine is an antibacterial.This compound is a contaminant of emerging concern (CECs).

• Definition

  ChEBI: A sulfonamide consisting of pyrimidine with methyl substituents at the 4- and 6-positions and a 4-aminobenzenesulfonamido group at the 2-position.

• Manufacturing Process

  A flask heated in an oil bath is filled with 600 ml water and 60 g (1 mol) glacial acetic acid (or an equivalent quantity of diluted acetic acid). While stirring 235 g (1.1 mols) anhydrous p-aminobenzenesulfonamidoguanidine (or an equivalent quantity of a nonanhydrous product) and 122 g (1 mol) sodium acetylacetonate 100% purity (or an equivalent quantity of product of a lower purity) are introduced into the flask while stirring.
  The temperature of the reaction mixture is brought to 102°C to 103°C, the mixture is further stirred at this temperature during 24 hours. The pH value of the mixture, which should range between 5 and 6 is checked during the reaction.
  On expiry of the reaction period heating is cut off, the mass being cooled or allowed to cool down to 60°C.
  Filtering under suction is effected, the solids on the filter being washed with 100 ml water at 80°C.
  After drying of the product on the filter 256 g of 2-paminobenzenesulfonamido- 4,6-dimethylpyrimidine, melting point 196°C to 197°C, purity 99.5% are obtained. The output is 92% of the theory calculated with respect to the sodium acetylacetonate employed.

• Therapeutic Function

  Antimicrobial

• Weltgesundheitsorganisation (WHO)

  Sulfadimidine, a sulfonamide anti-infective agent, was introduced in 1942 for the treatment of bacterial infections. The importance of sulfonamides has subsequently decreased as a result of increasing resistance and their replacement by antibiotics which are generally more active and less toxic. The sulfonamides are known to cause serious adverse effects such as renal toxicity, sometimes fatal exfoliative dermatitis and erythema multiforma and dangerous adverse reactions affecting blood formation such as agranulocytosis and haemolytic or aplastic anaemia. Sulfadimidine is still used in some countries as a injectable or oral antimicrobial for susceptible infections.

• Antimicrobial activity

  This drug is used for pneumococcal, staphylococcal, and streptococcal infections as well as for sepsis, gonorrhea, and other infectious diseases. Synonyms of this drug are sulfadiamezin and sulfadimidin.

• Allgemeine Beschreibung

  Sulfamethazine’splasma half-life is 7 hours. This compound is similar inchemical properties to sulfamerazine and sulfadiazine butdoes have greater water solubility than either. Its pKa is 7.2.Because it is more soluble in acid urine than sulfamerazineis, the possibility of kidney damage from use of the drug isdecreased. The human body appears to handle the drugunpredictably; hence, there is some disfavor to its use in thiscountry except in combination sulfa therapy (in trisulfapyrimidines,USP) and in veterinary medicine.

• Allgemeine Beschreibung

  Odorless sticky, white or creamy-white crystalline powder. Slightly bitter taste. An antibacterial.

• Air & Water Reaktionen

  Water solubility increases rapidly with increasing pH [Merck]. Insoluble in water.

• Reaktivität anzeigen

  Sulfamethazine is sensitive to light and may also be sensitive to heat. The presence of oxygen and moisture may accelerate the effects of heat and light .

• Brandgefahr

  Flash point data for Sulfamethazine are not available; however, Sulfamethazine is probably combustible.

• Pharmazeutische Anwendungen

  2-Sulfanilamido-4,6-methylpyrimidine (syn: sulphamethazine, sulfamezathine). A water-soluble compound, unstable on exposure to light. It is usually administered by mouth and is a component of some triple sulfonamide combinations.
  The spectrum is typical of the group, but sulfadimidine exhibits relatively low potency. It is well absorbed after oral administration. It is extensively metabolized, predominantly by acetylation. The mean plasma half-life (1.5–5 h) varies with acetylator status.
  In addition to side effects common to the group, a serious interaction between ciclosporin (cyclosporin A) and sulfadimidine, leading to reduced ciclosporin levels, has been reported.

• Biochem/physiol Actions

  Sulfamethazine is an antimicrobial sulfur drug that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfamethazine is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid. It induces CYP3A4 expression and is acetylated by N-acetyltransferase. It exhibits sex dependent pharmacokinetics, metabolized by the male specific isoform CYP2C11. Sulfamethazine is bacteriostatic.

• Sicherheitsprofil

  Moderately toxic by intravenous and intraperitoneal routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of SOx and NOx.

• Synthese

  Sulfamethazine, N1 -(4,6-dimethyl-2-pyrimidinyl)sulfanilamide (33.1.13), is also synthesized in the aforementioned manner by reacting 4-acetylaminobenzenesulfonyl chloride with 2-amino-4,6-dimethylpyrimidine, which is in turn synthesized by condensing acetylacetone with guanidine followed by hydrolysis of the acetylamino group using a base.

• läuterung methode

  Crystallise it from dioxane or aqueous dioxane. [Caldwell et al. J Am Chem Soc 63 2188 1941, Roblin et al. J Am Chem Soc 64 567 1942, Beilstein 25 III/IV 2215.]
