Dapsone

Dapsone (4,4′-Diaminodiphenyl sulfone) is an orally active and blood-brain penetrant sulfonamide antibiotic with bacteriostatic, antimycobacterial and antiprotozoal activities[1]. Dapsone exerts effective antileprosy activity and inhibits folate synthesis in cell extracts of M. leprae. Dapsone is used for dermatologic disorder research, including leprosy, dermatitis herpetiformis, acne vulgaris et al[2][3].
