Sulfamerazine
Sulfamerazine is only found in individuals that have used or taken this drug.It is a sulfanilamide that is used as an antibacterial agent. [PubChem]Sulfamerazine is a sulfonamide drug that inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase). Sulfamerazine is bacteriostatic in nature. Inhibition of dihydrofolic acid synthesis decreases the synthesis of bacterial nucleotides and DNA.

dapsone hydroxylamine
dapsone hydroxylamine is a metabolite of dapsone. Dapsone (diamino-diphenyl sulfone) is a medication most commonly used in combination with rifampicin and clofazimine as multidrug therapy (MDT) for the treatment of Mycobacterium leprae infections. It is also second-line treatment for prophylaxis (prevention) against Pneumocystis pneumonia (PCP) caused by Pneumocystis jirovecii (formerly P. carinii) in HIV patients in whom CD4 counts are below 200/mm.
