sulfachlorpyridazine

Sulfachlorpyridazine is a synthetic small molecule belonging to the sulfonamide class of antibiotics. It acts as a broad-spectrum antibacterial agent, effective against both gram-positive and gram-negative bacteria, including *Escherichia coli*. Its primary use is in veterinary medicine for the treatment of infections such as diarrhea (colibacillosis) in calves and swine caused or complicated by *E. coli*[1][4][5]. The mechanism of action involves competitive inhibition of the bacterial enzyme dihydropteroate synthase, thereby blocking dihydrofolic acid synthesis required for folic acid production and ultimately inhibiting bacterial growth[6][8]. Sulfachlorpyridazine is approved for veterinary use and may also be used to study metabolic pathways in microbiology research.
