Sulfanilamide

Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. Powdered sulfanilamide was used by the Allies in WWII to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to previous wars. Modern antibiotics have supplanted sulfanilamide on the battlefield; however, sulfanilamide remains in use for treatment of vaginal yeast infections.

The term "sulfanilamides" is also used to describe a family of molecules containing these functional groups. Examples include:

Mechanism of action

As a sulfonamide antibiotic, sulfanilamide functions by competitively inhibiting (i.e., by acting as a substrate analogue) enzymatic reactions involving para-aminobenzoic acid (PABA). PABA is needed in enzymatic reactions that produce folic acid, which acts as a coenzyme in the synthesis of purines and pyrimidines. Mammals do not synthesize their own folic acid so are unaffected by PABA inhibitors, which selectively kill bacteria.
