Sulfamerazine

4-amino-N-(4-methylpyrimidin-2-yl)benzene-1-sulfonamide

C11H12N4O2S (264.0680932)

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.
