CAS No.: 298-93-1
Synonyms: MTT; Thiazolyl Blue Tetrazolium bromide; Methylthiazolyldiphenyl-tetrazolium bromide
Thiazolyl Blue (MTT) is a cell-permeable and positively charged tetrazolium dye that is used to detect reductive metabolism in cells. Thiazolyl Blue is taken up by cells through the plasma membrane and then reduced to formazan by intracellular NAD (P) H-oxidoreductases. Thiazolyl Blue is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis .

Synonyms: 2,3,5-Triphenyltetrazolium chloride; TPTZ; TTC
Tetrazolium Red (2,3,5-Triphenyltetrazolium chloride; TTC) is a not brain-penetrant, colorless, water-soluble dye that is reduced by mitochondrial enzymes to a deep red, water-insoluble compound (formazan) mainly in the mitochondria of living cells. Tetrazolium Red is used to observe the activity of dehydrogenase, and it turns colorless to red when exposed to hydrogen. Tetrazolium Red distinguishes between surviving and infarcted brain tissue after stroke. Tetrazolium Red has been used to stain heart tissue to measure the extent of acute lesions and also used to stain brain tissue to detect the size of the infarcted area. The absorption wavelength of Tetrazolium Red is 570 nm .

Methacholine (Acetyl-β-methylcholine) choride is a potent muscarinic-3 (M3) agonist. Methacholine choride acts directly on acetylcholine receptors on smooth muscle causing bronchoconstriction and airway narrowing. Methacholine choride shows a high sensitivity to identify bronchial hyperresponsiveness (BHR). Methacholine choride can be used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in the assessment of individuals with asthma-like symptoms and normal resting expiratory flow rates .

Synonyms: (-)-Cotinine; (S)-Cotinine; NIH-10498
Cotinine ((-)-Cotinine) is an orally active alkaloid found in tobacco and is the primary metabolite of nicotine. Cotinine is metabolized by CYP2A13 into trans-3'-hydroxycotinine. Cotinine is used as a biomarker to measure exposure to tobacco smoke components. Cotinine has vasodepressor activity. The mixture of cotinine and nicotine (Nicotine) has antiproliferative activity against pterygium. (S)-(-)-Cotinine activates nicotinic acetylcholine receptors (nAChR) in a calcium-dependent manner, leading to the release of dopamine (Dopamine, HY-B0451). Cotinine ((-)-Cotinine) is used in research related to cardiovascular and inflammatory diseases .
