Sulfamethoxazole sodium
Based on 25 publication(s) in Google Scholar
Sulfamethoxazole (Ro 4-2130) sodium is a sulfonamide antibiotic with a widespread antibacterial activity. Sulfamethoxazole sodium inhibits bacterial folate metabolism by competing with 4-Aminobenzoic acid (HY-B1008) (PABA) to act on dihydropteroate synthetase and dihydropteroate reductase. Sulfamethoxazole sodium can be used for the study of urinary tract infections (UTIs), prostatitis, and bronchitis.

Sulfamethoxazole (0.01-1.28 mg/mL; 120 h) sodium inhibits P. lutzii mitochondrial activity[1].
Sulfamethoxazole (0.01 mg/mL; 1-2 h) sodium acts in P. lutzii as a competitor for amino acid, nucleic acids and folate cofactor biosynthesis, disrupting mitochondrial functions[1].
Sulfamethoxazole sodium at different concentrations, by using the whole-cell patch clamp recording method, inhibits the KATP channel currents in mouse pancreatic β cells in a dose-dependent manner, and the IC50 is 0.46 mM[3].
Sulfamethoxazole sodium at different concentrations, through the static incubation assay of islets, stimulates insulin secretion in mouse islets. It can stimulate insulin secretion at a low concentration (0.1 mM) under high-glucose (10 mM) conditions and only at a high concentration (10 mM) under low-glucose (2 mM) conditions[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
