Prontosil

Prontosil is an antibacterial drug of the sulfonamide group. It has a relatively broad effect against gram-positive cocci but not against enterobacteria. One of the earliest antimicrobial drugs, it was widely used in the mid-20th century but is little used today because better options now exist. The discovery and development of this first sulfonamide drug opened a new era in medicine, because it greatly widened the success of antimicrobial chemotherapy in an era when many physicians doubted its still largely untapped potential. At the time, disinfectant cleaners and topical antiseptic wound care were widely used but there were very few antimicrobial drugs to use safely inside living bodies. Antibiotic drugs derived from microbes, which we rely on heavily today, did not yet exist. Prontosil was discovered in 1932 by a research team at the Bayer Laboratories of the IG Farben conglomerate in Germany.
