Sulfadimidine (also sulfamethazine ) is an antibiotic from the group of sulfonamides , which is used as a sodium salt in veterinary medicine for the treatment of bacterial and parasitic infectious diseases (for example coccidiosis or diphtheroid diseases). In contrast to other sulfonamides, the medium-acting drug is used therapeutically as a single substance.
history
Sulfadimidine was discovered by Ward Blenkinsop in 1942 , by ICI in 1943, by Sharp & Dohme in 1946, and by Ist in 1964. Chemioterap. Ital. patented. The patent protection has now expired. The substance was brought onto the market as a diazil by the company Cilag (see also Bracco (company) ).
Extraction and presentation
Sulfadimidine can be obtained by reaction of 4-acetylaminobenzenesulfonyl chloride with 2-amino-4,6-dimethylpyrimidine and subsequent hydrolysis of the acetylamino group is synthesized. For this, the 2-amino-4,6-dimethylpyrimidine is in turn produced by condensation of acetylacetone with guanidine . It can also be prepared directly by reacting sulfanilylguanidine with acetylacetone.
Clinic and Pharmacology
Sulfadimidine competitively inhibits an enzyme in the metabolic pathway of folic acid synthesis, which catalyzes the formation of dihydropteroic acid. The toxicity of the antibiotic is low. Some chickens are an exception , as toxic effects can occur even in the therapeutic dose range. After use, sulfadimidine lowers the laying performance.
Trivia
Sulfadimidine is not a poison for certain soil-dwelling bacteria, but rather a welcome source of food. The compound that is used in animal husbandry reaches fields and the soil via the manure. The bacteria, which belong to the genus Microbacterium , use the nitrogen and carbon from the chemical compound specifically for their metabolism.
