    摘要: Chromogenic enzyme substrate compounds comprising a dibenz[b,e] [1,4]oxazepinone or dibenzo[b,e][1,4]thiazepinone nucleus having an enzyme-cleavable group such as a radical of a sugar, carboxylic acid, amino acid, peptide, phosphoric acid, or sulfuric acid. The substrate compounds are, in general, highly soluble in aqueous media and only slightly colored, and produce, upon enzyme cleavage, a chromogen exhibiting a large change in absorbance and a pKa below 7. Such substrates find use as indicators for the determination of enzyme analytes and enzymes used as markers in a variety of assays, including immunoassays.
