ECHEMI Editorial Reference

Sulfanilamide is a competitive inhibitor for bacterial enzyme dihydropteroate synthetase with IC50 of 320 μM.Target: dihydropteroate synthetase; AntibacterialSulfanilamide containing the sulfonamide functional group displays inhibitory activity for dihydropteroate synthetase partially purified from Escherichia coli which normally uses para-aminobenzoic acid (PABA) for synthesizing the necessary folic acid acting as a coenzyme in the synthesis of purine, pyrimidine and other amino acids,
Sulfanilamide is a white powder. pH of 0.5% aqueous solution: 5.8-6.1. (NTP, 1992)|Solid
Sulfanilamide is a white powder. pH of 0.5% aqueous solution: 5.8-6.1. (NTP, 1992)|Sulfanilamide is a sulfonamide in which the sulfamoyl functional group is attached to aniline at the 4-position. It has a role as an EC 4.2.1.1 (carbonic anhydrase) inhibitor, an antibacterial agent and a drug allergen. It is a substituted aniline, a sulfonamide antibiotic and a sulfonamide.|Sulfanilamide is a molecule containing the sulfonamide functional group attached to an aniline.|Sulfanilamide is an organic sulfur compound structurally similar to p-aminobenzoic acid (PABA) with antibacterial property. Sulfanilamide competes with PABA for the bacterial enzyme dihydropteroate synthase, thereby preventing the incorporation of PABA into dihydrofolic acid, the immediate precursor of folic acid. This leads to an inhibition of bacterial folic acid synthesis and de novo synthesis of purines and pyrimidines, ultimately resulting in cell growth arrest and cell death.|A short-acting sulfonamide used as an anti-infective agent. It has lower anti-bacterial activity than SULFAMETHOXAZOLE.
