Substrats d'enzymes

2-Nitrophenyl 2,3-di-O-acetyl-4-O-triethylsilyl-b-D-xylopyranoside is a chromogenic substrate for enzmatic assays to measure xylosidase activity. It is a derivative of xylose that can be hydrolyzed by xylosidase to release the yellow-colored 2-nitrophenyl group, which can be detected spectrophotometrically. By modifying the xylose molecule with acetyl and triethylsilyl groups, the enzyme substrate becomes more stable and resistant to degradation. This substrate is commonly used in the study of plant biomass degradation and in the detection of xylosidase activity in microorganisms.

2-Aminophthalylhydrazido 2-acetamido-2-deoxy-b-D-glucopyranoside is a chromogenic substrate that is used as a diagnostic in biological research. It reacts with enzymes to form fluorescent products, and can be used to detect the presence of bacteria and fungi. This product has a CAS number of 128879-80-1 and can be used for food testing, environmental testing, or bioluminescence. It is an important component in the development of new antibiotics.

4-Nitrophenyl 3,4-O-isopropylidene-a-D-galactopyranoside is a chemiluminescent substrate for detecting beta-galactosidase activity in bacteria. This product is a high purity, high quality compound that can be used as a culture media and environmental testing agent. It has been shown to be effective in diagnostics, chromogenic substrate, and enzyme substrate reactions. 4NPPG has been shown to be a fluorogenic substrate for beta-galactosidase assay and can be used as food testing agent with conjugate.

4-Methylumbelliferyl alpha-L-idopyranoside is a fluorogenic substrate for alpha-L-iduronidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl alpha-L-idopyranosideas a substrate for measuring the alpha-L-iduronidase activity is used for Mucopolysaccharidosis I diagnosis and Hurler syndrome screening.

4-Nitrophenyl b-D-thiomannopyranoside acts as a substrate for β-mannosidase and thioglycoligase. Upon enzymatic cleavage, these substrates release 4-nitrophenol, a yellow chromophore that can be detected spectrophotometrically at 405 nm, facilitating quantitative measurements of enzymatic activity. Consequently, these substrates are widely used in biochemical research, clinical diagnostics, and drug discovery for evaluating the function of specific enzymes in various biological processes.

2-Nitrophenyl-2,3,4-tri-O-acetyl-b-D-glucuronide methyl ester is a tri-O-acetylated glucuronide substrate commonly used in chromogenic assays to detect the activity of beta-glucuronidase. Upon hydrolysis by the enzyme, the substrate releases 2-nitrophenol, which can be spectrophotometrically. The substrate is widely used in diagnostic tests to assess bacterial and fungal infections, as well as in drug metabolism studies.

Fluorogenic substrate used to differentiate cytochrome P450 monooxygenases

Naphthol AS-BI b-D-glucopyranoside is a substrate for enzymes such as β-glucosidase and β-glycosidase. It has been used in diagnostic tests to detect the presence of amylase, lipase, α-amylase, or maltase in urine and feces. In biochemistry, naphthol AS-BI b-D-glucopyranoside is often used as a chromogenic or fluorogenic substrate for the detection of β-galactosidases and other glycosidases. This product has also been used in the detection of bacteria in culture media. Naphthol AS-BI b-D-glucopyranoside is a high quality reagent that can be used for chemiluminescence experiments, food testing, and environmental testing.
