Novel heterocyclic compounds which generate chemiluminescence on reaction with a phosphatase enzyme are provided as well as a process for their preparation and intermediates useful therein. The compounds comprise a nitrogen, oxygen or sulfur-containing heterocyclic ring system bearing an exocyclic carbon-carbon double bond. The double bond is further substituted at the distal carbon with a phosphate group and an oxygen or sulfur atom-containing group. Novel compositions further comprising a cationic aromatic compound (CAC) in addition to the heterocyclic phosphate compound are provided. The addition of the CAC in the composition greatly increases the production of chemiluminescence and provides improved detection sensitivity. Compositions further comprising an anionic surfactant and a non-ionic surfactant provide additional improvements in detection sensitivity. The novel chemiluminescent compounds and compositions are useful in methods for producing light and in assays for phosphatase enzymes and enzyme inhibitors and in assays employing enzyme-labeled specific binding pairs.
本发明提供了一种产生化学发光的新型杂环化合物,其与磷酸酶酶反应时会产生化学发光,并提供了其制备方法和有用中间体。该化合物包括一个含氮、氧或硫的杂环环系,其带有一个外环碳-碳双键。该双键在远端碳上进一步取代了一个磷酸酯基团和一个含氧或硫的原子基团。此外,还提供了一种新型组合物,其中除了杂环磷酸酯化合物外,还包括一个阳离子芳香化合物(CAC)。在组合物中加入CAC可以极大地增加化学发光的产生,并提高检测灵敏度。进一步包括阴离子表面活性剂和非离子表面活性剂的组合物提供了额外的检测灵敏度改进。新型化学发光化合物和组合物可用于产生光的方法,以及用于磷酸酶酶和酶抑制剂的测定和使用酶标记的特异性结合对的测定。
