Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial. Chemically, it is a molecule containing the sulfonamide functional group attached to an aniline. As a sulfonamide antibiotic, it functions by competitively inhibiting (i.e., by acting as a substrate analogue) enzymatic reactions involving para-aminobenzoic acid (PABA).[1] PABA is needed in enzymatic reactions that produce folic acid which acts as a coenzyme in the synthesis of purine, pyrimidine and other amino acids.
The term "sulfanilamides" is also used to describe a family of molecules containing these functional groups. Examples include:
Gerhard Domagk, who directed the testing of the prodrug Prontosil in 1935,[2] and Jacques and Thérèse Tréfouël, who along with Federico Nitti and Daniel Bovet in the laboratory of Ernest Fourneau at the Pasteur Institute, determined sulfanilamide as the active form,[3] are generally credited with the discovery of sulfanilamide as a chemotherapeutic agent. Domagk was awarded the Nobel Prize for his work.[4]
