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 beta-glucuronidase activity, an enzyme involved in the metabolism of glucuronides. Upon cleavage by beta-glucuronidase, the substrate produces a magenta-colored product, allowing for easy visualization and measurement of enzyme activity.
