• Drug Groups: approved
• Description: Sulfanilamide is a molecule containing the sulfonamide functional group attached to an aniline. [Wikipedia]
• Indication: For the treatment of vulvovaginitis caused by Candida albicans.
• Pharmacology: Sulfanilamide is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-aminobenzoic acid in the folic acid metabolism cycle. Bacterial sensitivity is the same for the various sulfonamides, and resistance to one sulfonamide indicates resistance to all. Most sulfonamides are readily absorbed orally. However, parenteral administration is difficult, since the soluble sulfonamide salts are highly alkaline and irritating to the tissues. The sulfonamides are widely distributed throughout all tissues. High levels are achieved in pleural, peritoneal, synovial, and ocular fluids. Although these drugs are no longer used to treat meningitis, CSF levels are high in meningeal infections. Their antibacterial action is inhibited by pus.
• Toxicity: Oral, mouse LD₅₀ = 3700 mg/kg; Intravenous, mouse LD₅₀ = 621 mg/kg; Oral, rabbit LD₅₀ = 1300 mg/kg. Side effects include itching, burning, skin rash, redness, swelling, or other sign of irritation not present before use of this medicine and long-term use of sulfonamides may cause cancer of the thyroid gland.
• Affected Organisms: Candida albicans and other yeasts
• Absorption: Sulfonamides are absorbed through the vaginal mucosa. There are no pharmacokinetic data available describing how much of an intravaginal dose reaches the systemic circulation.

• Description: Infection

Biological Activity

• Description: Sulfanilamide (Sulphanilamide) is a competitive inhibitor for bacterial enzyme dihydropteroate synthetase with IC50 of 320 μM.
• Targets: Dihydropteroate synthetase (DHPS)
• IC50: 320 μM ^[1]
• In Vitro: Sulfanilamide 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] Sulfanilamide moderately inhibits the growth of bacterial cells harboring plasmodium falciparum pKOS-pfPPPK-DHPS (His) with IC50 of 380 uM. ^[3]
• In Vivo: 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. ^[4]

Protocol

• Protocol: Kinase Assay ^[1]
• Assay of dihydropteroate synthetase activity: The dihydropteroate synthetase activity is measured by a modification of the radioactive assay based on the incorporation of ^14C-PABA into dihydropteroate. The reaction mixture in test tubes (1 by 7 cm) is prepared in 0.4 mL of 100 mM Tris-HCl buffer (pH 8.5) (containing 10 mM of MgCl₂, 50 mM of 2-ME, 0.12 mM of hydroxymethyldihydropteridine pyrophosphate, 0.01 mM of 14C-PABA, a set of concentrations of Sulfanilamide and 0.2 mg partially purified dihydropteroate synthetase extract), and incubated for 1 hour at 37 °C. The reactions are stopped immediately by the addition of 25 μM of EDTA (pH 8.3) to each reaction mixture, then evaporated to dryness under reduced pressure and redissolved in 0.075 mL of 0.05 M Tris (pH 8.0). 0.05 mL of the above mixture is applied (each in an area of 1.0 by 4.0 cm) to Whatman 3MM chromatography paper. The chromatograms are developed by descending chromatography with 0.1 M potassium phosphate buffer (pH 7.0), for 4 hours at 25 °C. Under these conditions, pteroate (dihydropteroate is oxidized to pteroate during the evaporation step) remains at the origin, whereas unreacted ^14C-PABA migrates with an Rf value of 0.78. Areas corresponding to the origin of the developed chromatograms are cut out and counted in a liquid scintillation counter. The concentration of Sulfanilamide required for 50% inhibition of dihydropteroate synthetase activity represents IC50.
• Protocol: Animal Study ^[4]
• Animal Models: Male Sprague-Dawley rats
• Formulation: Thoroughly mixed into the daily ration of pulverized food and compounded into pellets.
• Doses: 100 mg/kg
• Administration: Orally taken every day
