Signalling compounds for use in methods of detecting hydrogen peroxide

Abstract

Compounds useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula: 1 is reacted with peroxide. Sig is an aromatic or heteroaromatic ring group, B is a boron atom, and R5 and R6 are independently selected from hydrogen and lower alkyl groups and can be joined together as a straight or branched alkylene chain forming a five or six-membered ring. A detectable product compound of the formula Sig-OH Is produced and detected by measuring color, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The compounds can be used for detection in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
