Sulfadoxine is a broad-spectrum sulfonamide antibiotic effective against gram-negative and gram-positive bacteria. It is commonly used against malaria, especially Plasmodium falciparum malaria with chloroquine resistance. It has been used to study Toxoplasma gondii infections and to prevent infections in post-surgical animal models.

Sulfamerazine is a sulfonamide antibiotic useful against a wide variety of gram-negative and gram-positive bacteria.It is involved in the characterization of chitosan membranes used for transporting drugs.

Sulfonamide antibiotics are derived from a chemical called sulfanilamide. They function through inhibiting the conversion of p-aminobenzoic acid to dihydropteroate, an essential step in the synthesis of folic acid. By preventing the production of folate in bacteria, the sulfonamide antibiotics ultimately suppress bacterial DNA replication.

Sulfamethazine is broad-spectrum sulfonamide antibiotic targeting bacteria causing bronchitis and urinary tract infections. It is used in disposition and depletion studies of kinetics and to develop procedures used for quantification. Sulfamethazine is also an inducer of CYP3A4.

Sulfamonomethoxine is a long-acting sulfonamide antibiotic. It is used in blood kinetic studies as well as to study the formation of capsules in Bordetella bronchiseptica. Sulfamonomethoxine is used to combat hyperpyrexia of unknown etiology.

Tamoxifen citrate is an anti-cancer agent and protein kinase C inhibitor. It has been shown to induce apoptosis in human malignant glioma cells and to block VEGF production in breast cancer cells. Additionally, tamoxifen’s effects on radiation sensitivity have been studied. It has been used to analyze steroid receptors on human breast cancer cells and to study triacylglycerol accumulation in the liver. Tamoxifen is an estrogen receptor activator.

TAPS is a zwitterionic buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is part of the Tris family of buffers and is useful for a pH range of 7.7 – 9.1. TAPS is commonly used in capillary electrophoresis to analyze DNA and in planar chromatography to separate dyes. It is the preferred culture media buffer used for dinoflagellate experiments, allowing for minimal pH change and maximal growth. TAPS may form a complex with some common metals so stability constants and concentrations should be taken into account when choosing this buffer. TAPS is capable of inhibiting connexin channels in animal cells.

Tazobactam is a β-lactamase inhibitor useful in combination with β-lactam antibiotics to increase their potency. It irreversibly inactivates β-lactamase enzymes, preventing them from degrading β-lactam antibiotics. Tazobactam has been used in combination with piperacillin and a variety of other antibiotics. Tazobactam is less soluble in aqueous solution than tazobactam sodium.

Tazobactam is a β-lactamase inhibitor derived from penicillin. It is used along with β-lactam antibiotics, to prevent their degradation by β-lactamase enzymes. Tazobactam is often used with piperacillin to increase its potency. Additionally, tazobactam is used in studies regarding β-lactamase and penicillinase inhibition.

TCEP-HCl is an odorless reducing agent suitable for protein applications and in the preparation for electrophoresis. TCEP is water soluble, is stable in a variety of solutions and is particularly useful in the labeling of cysteine residues with maleimides, preventing the cysteines from forming disulfide bonds. As a reducing agent, TCEP has many other desirable features.
