Products Description of 4,4'-Diaminodiphenylsulfone CAS#80-08-0
Dapsone is a sulfone-class antibacterial agent with strong activity againstMycobacterium lepraeand has been extensively used in the treatment of leprosy. As the first-line drug for leprosy therapy, it inhibits bacterial dihydrofolate synthase (DHPs), disrupts folic acid synthesis, and thereby interferes with bacterial protein production. In addition to its antibacterial action, dapsone exhibits notable anti-inflammatory effects, effectively scavenging toxic oxygen free radicals and other reactive substances generated following neutrophil stimulation. It also suppresses neutrophil aggregation and activation, reduces the release of inflammatory mediators, and consequently limits tissue damage. Studies indicate that an oral dose of 100 mg of dapsone achieves blood concentrations 500–600 times higher than the minimum inhibitory concentration required to suppressMycobacterium leprae. Recent research further shows that dapsone is applicable in the treatment of various infectious diseases, inflammatory dermatoses, autoimmune bullous disorders, urticaria, and other conditions, demonstrating a broad range of clinical indications.
