Sulfamerazine is a sulfonamide antibiotic.
1 It inhibits bacterial carbonic anhydrase by ~20% at a concentration of 500 μM.
2 In vivo, sulfamerazine (500 mg/L) reduces severity of peribronchitis and inhibits cilia-associated respiratory
Bacillus colonization in mice.
3 It also prevents death of
Toxoplasma-infected mice.
1 Sulfonamide class antibiotics, of which sulfamerazine is a member, are bacteriostatic and inhibit bacterial synthesis of dihydrofolic acid by competing with 4-aminobenzoic acid (Item No.
18659) for binding to dihydropteroate synthase.
4 Formulations containing sulfamerazine have been used for the treatment of pneumonia and typhoid fever.
