AffiAB® Anti-Sulfadimidine Antibody [HuaM009-51B]

Sulfamethazine is a sulfonamide consisting of pyrimidine with methyl substituents at the 4- and 6-positions and a 4-aminobenzenesulfonamido group at the 2-position. It has a role as an antiinfective agent, a carcinogenic agent, a ligand, an antibacterial drug, an antimicrobial agent, an EC 2.5.1.15 (dihydropteroate synthase) inhibitor, an environmental contaminant, a xenobiotic and a drug allergen. It is a member of pyrimidines, a sulfonamide and a sulfonamide antibiotic. It derives from a sulfanilamide. Sulfamethazine is a sulfonamide drug that inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase). Sulfamethazine is bacteriostatic in nature. Inhibition of dihydrofolic acid synthesis decreases the synthesis of bacterial nucleotides and DNA. Sulfamethazine may cause nausea, vomiting, diarrhea and hypersensitivity reactions. Hematologic effects such as anemia, agranulocytosis, thrombocytopenia and hemolytic anemia in patients with glucose-6-phosphate dehydrogenase deficiency may also occur. Sulfamethoxazole may displace bilirubin from albumin binding sites causing jaundice or kernicterus in newborns. Sulfamethazine produces thyroid tumors in mice and rats by a non-genotoxic mechanism, which involves inhibition of thyroid peroxidase resulting in alterations in thyroid hormone concn and incr secretion of thyroid stimulating hormone. Consequently, sulfamethazine would be expected not to be carcinogenic to humans exposed to doses that do not alter thyroid hormone homeostasis. Evidence from epidemiological studies and from toxicological studies in experimental animals provide compelling evidence that rodents are substantially more sensitive than humans to the development of thyroid tumors in response to thyroid hormone imbalance. This antibody does not cross-react with Sulfamethoxypyridazine and sulfamethoxazole.
