Chromogenic substrates of the formula A--O--B are described, in which A represents the radical in the ion A--O.sup.- of a compound A--OH, whose absorbance is measured photometrically after hydrolysis of A--O--B, while B is the radical in a compound B--OH which makes the compound specific for the reaction with a given enzyme, and where A--OH is a hydroxynitropyridine, a hydroxynitrobenzopyranone, a dibenzox(or thi)azine or a dibenzopyranone or a derivative thereof, and B is a sugar or sugar derivative, an amino acid or an oligopeptide or an inorganic acid. These compounds can be used for the detection and determination of hydrolases.
本文描述了化学配方为A--O--B的色原基质,其中A代表化合物A--OH中离子A--O.sup.-的基团,经A--O--B水解后,其吸收度在光度计下被测量,而B是化合物B--OH中的基团,使化合物特异地与给定的酶反应,其中A--OH是羟基硝基吡啶、羟基硝基苯并吡喃酮、二苯并氧(或硫)嗪或二苯并吡喃酮或其衍生物,而B是糖或糖衍生物、氨基酸或寡肽或无机酸。这些化合物可用于检测和测定水解酶。
