摘要:
IN WHICH R1 is hydroxyl, unsubstituted or substituted amino, wherein the substituent is an aliphatic, araliphatic, cycloaliphatic, heterocyclic or aromatic radical, which in turn is substituted by one or more of hydroxy, amino and alkoxy; R3, R2 and R5 are each one of hydrogen, amino, hydroxy or alkoxy and R4 is hydrogen or the substituent R1. The diagnostic agents can be used for analytical determinations involving, for example, glucose, galactose, amino acids, uric acid, peroxide, hemoglobin, peroxidase, etc. in samples, for example, constituting biological fluids such as blood, urine, spinal fluid, etc., milk, cosmetic and drug formulations, etc.
Diagnostic agents suitable for use in carrying out rapid analytical determinations of the presence and/or concentration of hydroperoxide substances which react with the liberation of hydrogen peroxide, peroxidase and peroxidate active substances comprising an indicator, i.e., chromogen, which is oxidized by hydrogen peroxide, peroxidase or peroxidate active substances to form a dyestuff, the color intensity of which is dependent on the peroxide, peroxidase or peroxidate active substance present in the test sample, wherein the chromogen is a compound having the formula:

摘要:
THERE ARE DISCLOSED DIAGNOSTIC AGENTS SUITABLE FOR USE IN CARRYING OUT RAPID ANALYTICAL DETERMINATIONS OF THE PRESENCE AND/OR CONCENTRATION OF HYDROPEROXIDE, SUBSTANCES WHICH REACT WITH THE LIBERATION OF JYDROGEN PEROXIDE, PEROXIDASE AND PEROXIDATE-ACTIVE SUBSTANCES. THE DIAGNOSTIC AGENTS OF THE INVENTION ARE ADAPTED FOR USE IN TEST PROCEDURES INVOLVING OPTICAL INSTUMENTS SUCHAS COLORMETERS AND PHOTOMETERS AND ALSO IN TEST PROCEDURES INVOLVING TEST PAPERS. THE DIAGNOSTIC AGENTS AS TAUGHT HEREIN COMPRISE AN INDICATOR I.E., CHROMOGEN, WHICH IS OXIDIZED BY HYDROGEN PEROXIDE AND PEROXIDASE OR PEROSIDATE ACTIVE SUBSTANCES TO FORM A DYESTUFF WHOSE INTENSITY IS DEPENDENT ON THE CONCENTRATION OF THE PEROXIDE, PEROXIDASE OR PEROXIDATE ACTIVE SUBSTANCE PRESENT IN THE TEST SAMPLE. THE INDICATOR I.E., CHROMOGEN IS A COMPOUND OF THE FORMULA:
(R4,R5,R6-PHENYL)-C(-R3)=N-(N(-R2))N-C(=X)-R1
WHERIN R1 IS AMINO OR AN ALIPHATIC, ARALIPHATIC, AROMATIC OR HETEROCYCLIC RADICAL WHICH MAY CARRY ONE OR MORE SUBSTITUENTS, OR A GROUP HAVING THE FORMULA:
WHEREIN R2 IS HYDROGEN, AN ALIPHATIC, AROMATIC OR HETEROCYCLIC RADICAL WHICH MAY CARRY ONE OR MORE SUBSTITUENTS, R3 IS HYDROGEN, ALKYL OR PHENYL AND MAY BE MONO- OR POLY SUBSTITUTED, R4 IS AMINO, HYDROXYL OR ALKOXY, R5 AND R6 ARE EACH HYDROGEN, AMINO, HYDROXY,ALKOXY OR ALKYL, X IS OXYGEN, SULFUR OR IMINO WHICH MAY BE SUBSTITUTED BY A GROUP AS DEFINED BY R1, N IS 0 OR 1, M IS 0,1 OR 2; AND WHEREIN X AND R1 AND R2 OR R1 AND R3 CAN BE JOINED TOGETHER TO FORM A RING. THE DIAGNOSTIC AGENTS CAN BE USED FOR ANALYTICAL DETERMINATIONS INVOLVING, FOR EXAMPLE, GLUCOSE, GALACTOSE, AMINO ACIDS, URIC ACID, PEROXIDE, HEMOGLOBIN, PEROXIDASE, ETC. IN SAMPLES, FOR EXAMPLE, CONSTITUTING BIOLOGICAL FLUIDS SUCH AS BLOOD, URINE, SPINAL FLUID, ETC., MILK, COSMETIC AND DRUG FORMULATIONS, ETC.
摘要:
Mucoviscidosis (cystic fibrosis) is detected in its early stages, particularly in the large-scale screening in newborn infants, by means of measuring the pathologically elevated protein content in the meconium, using a diagnostic agent comprising a protein test strip sealed to a longer plastic strip, applying meconium to the (flush) bottom portion of the combined strip, immersing the smeared portion of the strip in water, permitting water to wet the strip by ascending chromatography, and reading a color change in the strip as an indication of elevated protein content in the meconium.
