5-Bromo-4-chloro-3-indolyl acetate (5BCIA) is an enzyme substrate that has been shown to inhibit the activity of a number of enzymes, such as proteases and phosphatases. It has also been shown to inhibit the growth of a number of human pathogens, including Staphylococcus aureus, Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. 5BCIA inhibits bacterial growth by binding to the active site of the enzyme phosphatase and preventing it from hydrolyzing a phosphate group from ATP. This process is necessary for energy metabolism in all living cells. 5BCIA has been shown to be effective against methicillin resistant Staphylococcus aureus (MRSA).

Aldol® 515 caprylate hydrochloride is used as a bioluminescent substrate for enzyme activity measurements and as a fluorogenic substrate for detecting C8/C9-esterases, lipase activity yielding a red color.

5-Bromo-4-chloro-3-indoxyl-beta-D-xylopyranoside is a fluorogenic substrate that can be used to measure the activity of bacterial esterases. The enzyme cleaves the xylose moiety from 5-bromo-4-chloro-3-indoxyl, yielding indoxyl as an intermediate product. This reaction can be catalyzed by esterases found in bacteria, which hydrolyze esters containing a single hydroxyl group at one end and a carboxylic acid or alcohol at the other end. Indoxyl is fluorescent and can be detected using a fluorimeter. 5BX is also chromogenic, so it can be used as an enzyme substrate for detecting beta galactosidase activity in bacteria such as Mycobacterium smegmatis or Escherichia coli. 5BX is also used to detect chemilumines
