Sulfamethazine

Sulfamethazine is a sulfanilamide anti-infective agent. It has a spectrum of antimicrobial action similar to other sulfonamides. It 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). Sulfamethazine is bacteriostatic in nature. Inhibition of dihydrofolic acid synthesis decreases the synthesis of bacterial nucleotides and DNA.

Sulfamethoxazole

Sulfamethoxazole is a sulfonamide bacteriostatic antibiotic. Its primary activity is against susceptible forms of Streptococcus, Staphylococcus aureus, Escherichia coli, Haemophilus influenzae, and oral anaerobes. It is commonly used to treat urinary tract infections. In addition it can be used as an alternative to amoxicillin-based antibiotics to treat sinusitis. It can also be used to treat toxoplasmosis and it is the drug of choice for Pneumocystis pneumonia, which affects primarily patients with HIV.

Properties Suppliers
Sulfamide

Sulfamide is produced by the reaction of sulfuryl chloride with ammonia. It is an anti-infective agent that is used topically to treat skin infections and orally for urinary tract infections. It is used to treat infections of the eye and ear.Sulfamide is used as an intermediate for especially anti-ulcer agents.

Properties Suppliers
Sulfanilamide

Sulfanilamide is a sulfonamide antibacterial. Chemically, it is a molecule containing the sulfonamide functional group attached to an aniline. As an antibiotic, it functions by competitively inhibiting enzymatic reactions involving para-aminobenzoic acid (PABA). PABA is needed in enzymatic reactions that produce folic acid which acts as a coenzyme in the synthesis of purine, pyrimidine and other amino acids.

Properties Suppliers
Sulfaphenazole

Sulfaphenazole is a sulfonamide antibiotic that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase in bacteria.

Properties Suppliers
Sulfapyridine

Sulfapyridine is a sulfonamide antibiotic. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-aminobenzoic acid in the folic acid metabolism cycle. Sulfapyridine is a competitive inhibitor of the bacterial enzyme dihydropteroate synthetase.

Properties Suppliers
Sulphadimidine Sodium

Sulphadimidine sodium is a chemotherapeutic with bacteriostatic action against many Gram-positive and Gram-negative bacteria and against certain protozoa like Eimeria and Isospora species. Sulphadimidine is used for oral treatment of gastrointestinal infections, respiratory infections, Fowl Cholera and Coccidiosis in poultry, turkey and rabbits.

Properties Suppliers
Sulphaguanidine

Sulphaguanidine is a sulfanilamide anti-infective agent. It has a spectrum of antimicrobial action.It is used to treat bacillary dysentery,also as raw material of sulfadiazine drugs,as auxiliary material for other drugs.

Properties Suppliers
Tetracycline

Tetracycline is a broad spectrum polyketide antibiotic produced by the Streptomyces genus of Actinobacteria. It exerts a bacteriostatic effect on bacteria by binding reversible to the bacterial 30S ribosomal subunit and blocking incoming aminoacyl tRNA from binding to the ribosome acceptor site. It also binds to some extent to the bacterial 50S ribosomal subunit and may alter the cytoplasmic membrane causing intracellular components to leak from bacterial cells.It is used to treat bacterial infections such as Rocky Mountain spotted fever, typhus fever, tick fevers, Q fever, rickettsialpox and Brill-Zinsser disease,infections caused by Chlamydiae spp., B. burgdorferi (Lyme disease), and upper respiratory infections caused by typical (S. pneumoniae, H. influenzae, and M. catarrhalis) and atypical organisms (C. pneumoniae, M. pneumoniae, L. pneumophila),acne.

Properties Suppliers
Thiamphenicol

Thiamphenicol is an antibiotic. It is the methyl-sulfonyl analogue of chloramphenicol and has a similar spectrum of activity, but is 2.5 to 5 times as potent. It is used in many countries as a veterinary antibiotic, but is available in China and Italy for use in humans. Its main advantage over chloramphenicol is that it has never been associated with aplastic anaemia. It is also widely used in Brazil, particularly for the treatment of sexually transmitted infections and pelvic inflammatory disease.
