Methods and compound useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of formula
is reacted with peroxide. A detectable product compound of the formula Sig - OH or Sig-O is produced and detected by measuring color, absorbance, fluorescence, chemiluminescence or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The methods can be used as a detectable signal in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs. The signaling compound has the formula:
wherein B is a boron atom, 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 or an arylene ring, and R13 is independently selected from cyano, imine, carbonyl, thiazole, carbonyl-substitute thiazole and benzothiazole groups or a group
wherein Z is C-C double or triple bond or aromatic ring and n is 1 or 2.
本发明公开了用于检测过氧化氢来源的方法和化合物,其中含有一种式信号化合物
与过氧化氢反应。生成可检测的式 Sig - OH 或 Sig-O 产物化合物,并通过测量颜色、吸光度、荧光、化学发光或生物发光进行检测。信号化合物本身不具有可检测特性,或仅具有非常微弱的可检测特性。这些方法可在过氧化物或产生过氧化物的酶的检测中,以及在采用酶标记的特异性结合对的检测中用作可检测信号。信号化合物的化学式如下
其中 B 是硼原子,R5 和 R6 独立地选自氢和低级烷基,可连接成直链或支链亚烷基链,形成五元环或六元环或芳基环,R13 独立地选自氰基、亚胺、羰基、噻唑、羰基取代噻唑和苯并噻唑基团或一个基团。
其中 Z 为 C-C 双键或三键或芳香环,n 为 1 或 2。
