Dapsone was synthesized in 1908 by Fromm and Wittmann. The drug was approved by FDA for the treatment of such conditions as acne vulgaris, leprosy and dermatitis herpetiformis, also the drug is used off-label for many skin diseases. Although the exact mechanism of dapsone action is unknown, it is speculated that it acts as both anti-inflammatory and antimicrobial agent. It was demonstrated that dapsone suppresses ROS generation, inhibits neutrophil myeloperoxidase and eosinophil peroxidase and also inhibits bacterial dihydropteroate synthase.

Sulfacetamide is a synthetic sulfonamide antibiotic, which exerts its effect through inhibition of bacterial dihydrofolate synthetase, an enzyme responsible for the conversion of p-aminobenzoic acid into folic acid in bacterias. The topical formulation of the drug is prescribed for the treatment of acne vulgaris and the ophtalmic formulation is used in patients with eye infections.
