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 R
5
and R
6
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.
本发明揭示了一种用于检测
过氧化氢来源的化合物,其中公式1的信号化合物与过氧化物反应。Sig是芳香或杂芳基环团,B是
硼原子,R5和R6分别选自氢和低碳基团,并可以连接成直链或支链烷基链形成五元或六元环。产生公式Sig-OH的可检测产物化合物,并通过测量颜色,荧光,
化学发光或
生物发光来检测。信号化合物本身不具有可检测性或只具有非常弱的可检测性。这些化合物可用于检测过氧化物或产生过氧化物的酶的测定以及使用酶标记的特异性结合对的测定。
