- An enzyme that hydrolyzes the amino-terminal residue of a peptide that has a free amino group to release L-leucine, and is widely distributed in various tissues in the body and is also present in serum. It is known that the amount of the enzyme varies significantly depending on the state of the living body, and LAP activity increases in acute hepatitis, liver cancer, metastatic liver cancer, liver cirrhosis, biliary tract disease, etc. Therefore, LAP activity is one of the indicators of such diseases, and measuring this enzyme activity has become one of the indispensable testing methods for diagnosing these diseases.

の１つになつている。 γ-GTP is an enzyme involved in the metabolism of γ-glutamyl peptide in vivo, and is an enzyme that not only hydrolyzes γ-glutamyl peptide but also transfers the γ-glutamyl group to other peptides or amino acids. It is widely distributed in various tissues and is also present in serum. γ-GTP is known to vary significantly depending on pathological conditions, and serum γ-GTP
GTP shows markedly high levels in hepatostatic hepatitis, obstructive jaundice, primary liver cancer, metastatic liver cancer, etc.
In particular, inactive forms of chronic hepatitis show low levels, but active forms show high levels, and are generally specific to chronic liver diseases, making this diagnosis completely different from the various deviant enzymes that have been used clinically in the past. It has scientific significance, and measurement of serum γ-GTP activity has become one of the indispensable testing methods for diagnosing and understanding the pathology of such diseases.

た。 Conventionally, many methods for measuring LAP activity have been reported, but most of them are methods for determining LAP activity values by colorimetrically quantifying amine compounds liberated by LAP from synthetic substrates; One method is to colorimetrically quantify the yellow color of p-nitroaniline produced by the enzymatic action of LAP using L-leucyl-p-nitroanilide as the synthetic substrate. It has the disadvantage that the coloring wavelengths overlap, and it also has the disadvantage that measurement cannot be avoided by the influence of serum components, especially bilirubin dyes. Furthermore, L-leucyl-β-
A method using naphthylamide is mentioned, but in this method, the generated β-naphthylamine is coupled with 5-nitro-2-aminomethoxybenzenediazotate to form a dye, or the generated β-naphthylamine is combined with sodium nitrite. or p-dimethylaminobenzaldehyde or p-
This method involves condensing dimethylaminocinnamaldehyde to form a dye, which is then colorimetrically quantified, but the reaction process is complicated and requires strict operations, making it inconvenient as a testing method. However, the toxicity of β-naphthylamine, which is a standard substance, is extremely toxic, and it has recently become clear that it causes bladder tumors and cancer, so it has the drawback of requiring particularly strict precautions when using it as a carcinogen.

Using glutamyl-p-nitroanilide, γ-
One method is to colorimetrically quantify the yellow color of p-nitroaniline produced by the enzymatic action of GTP at 410 nm, but in order to avoid the influence of serum components, especially bilirubin pigments, it is necessary to strictly prepare a sample blank for each sample. The drawback was that it was difficult to obtain accurate measurements. Another method is to condense the produced p-nitroaniline with an aldehyde compound such as p-dimethylaminocinnamaldehyde or p-dimethylaminobenzaldehyde and measure the long wavelength red color, but the temperature has a large effect on the color sensitivity. There were problems with the reproducibility of measured values. A method has also been proposed in which the resulting p-nitroaniline is diazotized and condensed with 3,5-xylenol to measure the resulting red color, but this method has the drawback of requiring many reaction steps and lacking in simplicity. Furthermore, γ-L-
Examples include methods using glutamyl-β-naphthylamide, including colorimetric determination of β-naphthylamine liberated by γ-GTP as a diazonium salt, and oxidation with 3-methyl-2-benzothiazolinone hydrazone. There is a method of colorimetric determination by developing a color with a coloring agent, or a method of colorimetric determination by condensing the aldehyde compound as a coloring agent, but as mentioned above, the carcinogenicity of β-naphthylamine is generally pointed out, and the procedure is difficult. It lacks practicality in that it is complicated and takes a long time to measure.

方法である。 As mentioned above, the measurement method using the synthetic substrate of the present invention is not only capable of quickly and accurately measuring LAP and γ-GTP peptidase activity values because each reaction step is simple, but also allows for the rapid and accurate measurement of LAP and γ-GTP peptidase activity values. Since the color-forming compound usually has a maximum absorption in the vicinity of 500 to 750 nm, it is not easily affected by contaminants in the product sample and is a highly accurate method for measuring peptidase activity.
