用途: 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, exhibiting an IC 50 of 320 μM for dihydropteroate synthetasea and Km of 2.5 uM for PABA [1]. Sulfanilamide shows IC50 of 286.8 μg/mL for recombinant S. cerevisiae strains with wild-type FOL1 genes, but the single mutation 55Trp to 55Ala or 57Pro to 57Ser within the putative active site of the fungal DHPS confers resistance to Sulfanilamide with IC50 of >800 μg/mL [2]. Administration of Sulfanilamide with the dosage of 100 mg/kg/day is effective in the prevention of P. carinii infection in the immunosuppressed rat model. When the dosage of sulfaguanidine and Sulfanilamide reduced to 10 mg/kg/day, breakthrough P. carinii infection occurs in the rats [3]. 物理化学性质: CAS号:63-74-1 常用中文名:磺胺 常用英文名:Sulfanilamide 分子式:C6H8N2O2S 分子量:172.205 密度:1.4±0.1 g/cm3 沸点:400.5±47.0 °C at 760 mmHg 熔点:164-166 °C(lit.) 闪点:196.0±29.3 °C 储存条件:包装完整、轻装轻放,库房通风、远离明火、高温、与氧化剂分开存放 |
