5-Bromo-6-chloro-3-indolyl b-D-glucuronide cyclohexylammonium salt is a magenta enzyme substrate commonly used in biochemical assays. This compound is a derivative of indole, containing bromine and chlorine atoms at positions 5 and 6, respectively. The glucuronide moiety is attached to the indolyl ring, and the cyclohexylammonium cation serves as a counterion to balance the charge. This substrate is often utilized in the detection and quantification of β-glucuronidase activity, an enzyme involved in the metabolism of glucuronides. Upon cleavage by β-glucuronidase, the substrate produces a magenta-colored product, allowing for easy visualization and measurement of enzyme activity.

Medrysone is a synthetic glucocorticoid for topical use with anti-inflammatory and anti-allergic effects, altering gene expression to reduce inflammation.

Tetrabutylphosphonium p-toluenesulfonate is a fluorogenic substrate that is used in the diagnosis of cytochrome P450 enzymes. It is a ligand that binds to metal ions, such as copper and zinc. This compound is also used for the preparation of bioluminescent substrates for use in diagnostics and research.

6-Benzoyl-2-naphthylphosphate disodium salt is a chromogenic substrate used to detect and quantify alkaline phosphatase activity. After enzymatic hydrolysis, 6-benzoyl-2-naphthol is released, which can be detect or even further react with other reagents (e.g. Fast Red) to increase the intensity of the colorimetric signal. It is used in common applications such as ELISA, immunohistochemistry and Western Blotting.

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.
