Sulfadiazine-d4

Sulfadiazine-d4 is intended for use as an internal standard for the quantification of sulfadiazine by GC- or LC-MS. Sulfadiazine is a sulfonamide antibiotic that inhibits the growth of Gram-positive and Gram-negative bacteria. It inhibits dihydropteroate synthase (DHPS), which converts a pteridine and 4-aminobenzoic acid (PABA) to dihydropteroate, an intermediate in folate biosynthesis. Sulfadiazine inhibits recombinant P. carinii DHPS (IC50 = 0.19 μM). It is active against clinical isolates of M. tuberculosis (MIC90 = 10 mg/L) and of N. meningitidis (MICs = 5-2,000 mg/L). Sulfadiazine is also active against A. pleuropneumoniae, S. choleraesuis, S. typhimurium, P. multocida, S. equi, and S. suis (MIC90s = <0.5 mg/ml for all) when used in combination with trimethoprim. In vivo, sulfadiazine (40 mg/kg per day) increases survival in a mouse model of lethal T. gondii infection when administered in combination with pyrimethamine. Formulations containing sulfadiazine have been used in the treatment of rheumatic fever and various infections, and, in a dual treatment with pyrimethamine, to treat toxoplasmosis.
