Sulfanitran
Sulfanitran[edit | edit source]
Sulfanitran is a sulfonamide antimicrobial agent that has been used primarily in veterinary medicine. It belongs to the class of sulfa drugs, which are synthetic antimicrobial agents that contain the sulfonamide group. Sulfanitran is known for its effectiveness against certain bacterial infections in animals.
Chemical Properties[edit | edit source]
Sulfanitran is characterized by its chemical structure, which includes a sulfonamide group attached to an aromatic ring. This structure is crucial for its antimicrobial activity, as it mimics the structure of para-aminobenzoic acid (PABA), a substrate for bacterial dihydropteroate synthase. By competing with PABA, sulfanitran inhibits the synthesis of folic acid in bacteria, which is essential for their growth and replication.
Mechanism of Action[edit | edit source]
Sulfanitran, like other sulfonamides, acts as a competitive inhibitor of the enzyme dihydropteroate synthase. This enzyme is involved in the bacterial synthesis of folic acid, a vital component for the production of nucleic acids and ultimately, DNA. By inhibiting this enzyme, sulfanitran effectively halts bacterial growth, making it a bacteriostatic agent.
Uses in Veterinary Medicine[edit | edit source]
Sulfanitran has been used in the treatment of bacterial infections in livestock, particularly in poultry. It is effective against a range of Gram-positive and Gram-negative bacteria. Its use is primarily focused on controlling infections that can lead to economic losses in animal husbandry.
Safety and Regulation[edit | edit source]
The use of sulfanitran, like other veterinary drugs, is subject to regulation to ensure the safety of animal products for human consumption. Residues of sulfanitran in animal products are monitored to prevent potential adverse effects on human health. The withdrawal period for sulfanitran-treated animals must be observed to ensure that drug residues are below the permissible limits before the animals or their products enter the food supply.
