Curator's Comment: description was created based on several sources, including https://www.goldbio.com/product/3383/sulfamonomethoxine http://ft.chqmarket.com/en/1059-compound-sulfamonomethoxine-sodium-injection-baclean.html

Sulfamonomethoxine is a long-acting sulfonamide antibiotic. It is active against Streptococcus spp. (Including Streptococcus pneumoniae, Enterococcus spp.), Staphylococcus spp., Escherichia coli, Shigella spp., some strains of Proteus spp., Neisseria gonorrhoeae, Neisseria meningitides. Sulfamonomethoxine also active against Chlamydia spp., Toxoplasma gondii, Plasmodium. Rapidly absorbed from the gastrointestinal tract, it penetrates the BBB. The relatively low toxicity. Sulfamonomethoxine is a competitive inhibitor of dihydropteroate synthetase used to block the synthesis of folic acid. By preventing the production of folate in bacteria, the sulfonamide antibiotics ultimately suppress bacterial DNA replication.

Route of Administration: Oral

In Vitro Use Guide

It was shown that 9 strains of P. mallei were sensitive to sulfanilamides and their combinations with trimethoprim: sulfamonomethoxine + trimethoprim (2.5:1), etc. The activity of the sulfamonomethoxine combination with trimethoprim (sulfate) was lower.
