Chromogenic substrate for alkaline phosphatase

[2-Methoxy-4-(2-nitrovinyl)phenyl] beta-D-galactopyranoside is a chromogenic substrate (505 nm) for β-glucosidase.

4-Nitrophenyl lacto-N-tetraoside is a chromogenic substrate for enzymes that cleave lactose-specific linkages, such as beta-galactosidases. Upon enzyme cleavage, the pNP group is released, resulting in a yellow-colored solution that can be spectrophotometrically quantified at 405 nm. This substrate is commonly used in detecting lactose hydrolysis activity, such as in dairy industry for production optimization studies, or in microbiology for bacterial lactose fermentation assays. Its tetrasaccharide structure resembles that of lactose and makes it a specific substrate for lactose-utilizing enzymes. The properties of 4-nitrophenyl lacto-N-tetraoside make it a useful tool in enzyme kinetics studies and screening of new lactose-utilizing microorganisms.

4-Nitrophenyl 6-O-benzoyl-3,4-O-isopropylidene-a-D-galactopyranoside (4NBP) is a fluorogenic substrate for β-galactosidase. It has been used as an enzyme substrate in the detection of β-galactosidase activity. 4NBP is also used to detect the presence of galactose in culture media and as a chromogenic substrate in diagnostics.

Jalapeno green-Gal (Jalapeno green-beta-D-galactopyranoside) is a chromogenic indicator for beta-galactosidase activity. The colorless product is cleaved by lactose-utilizing bacteria in liquid media or on agar plates and yields a Jalapeno green colored precipitate. Jalapeno green-Gal can also be used as detecting agent for beta-galactosidase activity in reporter gene assays or for identification of positive transformants on agar plates when using the α-complementation approach.

4-Nitrophenyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-a-D-glucopyranoside is a synthetic compound with the ability to inhibit the enzyme glutamicum. It is a radionuclide that can be used as a focusing agent for gamma cameras and has been shown to be effective against corynebacterium glutamicum and other organisms. 4NP2AG was synthesized by reacting nitrophenol with acetamide in the presence of an acid catalyst and hydrogenating the product. The synthesis employs precession chemistry, which involves rotating a molecule around its axis at high speed to increase its concentration in one area. This treatment leads to a higher yield of desired product. 4NP2AG contains two acetamido groups on the glucopyranoside moiety, which are esterified with nitrophenol and acetic acid respectively. These moieties are

4-Nitrophenyl 2,6-di-O-benzoyl-a-D-galactopyranoside is a specialized chromogenic substrate for the accurate evaluation of α-galactosidase activity.
