Verfahren zur Bestimmung der C1-Esterase-Inhibitor-Procedure for the determination of the C1 esterase inhibitor
Aktivität von C1-Esterase-Inhibitor-hältigen Proben Die Erfindung betrifft ein Verfahren zur Bestimmung der C1-Esterase-Inhibitor-Aktivität von C1 -Esterase-Inhibitorhältigen Proben durch Vergleich der C1-Esterase-Aktivität einer standardisierten C1-Esterase-Präparation mit der Aktivität der gleichen standardisierten Präparation in Gegenwart der zu untersuchenden C1-Esterase-Inhibitorhältigen Probe, wobei die Differenz der erhaltenen Werte ein Maß für die Inhibitor-Aktivität der Probe darstellt.Activity of samples containing C1 esterase inhibitor The invention relates to a method for determining the C1 esterase inhibitor activity of C1 - Samples containing esterase inhibitor by comparing the C1 esterase activity of a standardized C1 esterase preparation with the activity of the same standardized Preparation in the presence of the C1 esterase inhibitor-containing sample to be examined, wherein the difference between the values obtained is a measure of the inhibitor activity of the Sample represents.
In menschlichen und tierischen Körperflüssigkeiten ist ein mit C1-Esterase~bezeichnetes Enzym vorhanden, welches mit einem ebenfalls vorhandenen Inhibitor bzw. Inaktivator einen inaktiven Komplex bildet. Bei verschiedenen Untersuchungen bzw. Behandlungen ist es von Bedeutung, den C1-Esterase-Inhibitor-Gehalt quantitativ zu bestimmen.In human and animal body fluids there is a C1-Esterase ~ Enzyme present, which with an also present inhibitor or inactivator forms an inactive complex. During various examinations or treatments it is important to quantitatively determine the C1 esterase inhibitor content.
Die chemische Struktur der C1-Esterase ist unbekannt, jedoch weiß man aus "Thrombosis Research" 18, No. 6,847-859 (1980), daß im C1-Esterase-Molekül verschiedene aktive Zentren vorhanden sind, von denen eines durch den C1-Esterase-Inhibitor blockierbar ist.The chemical structure of C1 esterase is unknown, but it is white from "Thrombosis Research" 18, no. 6,847-859 (1980) that in the C1 esterase molecule different active centers are present, one of which is through the C1 esterase inhibitor can be blocked.
Eine bekannte Methode zur Bestimmung der Aktivität des C1-Esterase-Inhibitors beruht auf der esterspaltenden Wirkung von C1-Esterase. Als Substrat wird ein Ester einer aromatischen Aminosäure (z.B.N-Acetyl-L-Tyrosinäthylester ) verwendet, wobei der Ester gespalten und die freigesetzte Säure bestimmt wird (Proc. Soc. Exp.A well-known method for determining the activity of the C1 esterase inhibitor is based on the ester-splitting effect of C1-esterase. An ester is used as the substrate an aromatic amino acid (e.g. N-acetyl-L-tyrosine ethyl ester ) used, whereby the ester is cleaved and the acid released is determined (Proc. Soc. Exp.
Biol.Med. 101, 608-611 (1959), J. Clin. Pathol. 1980; 33, 167-170). Diese esterolytische Bestimmungsmethode ist ungenau und aufwendig und sie wird den tatsächlichen in vivo-Reaktionen des Enzyms nicht gerecht.Biol.Med. 101: 608-611 (1959) J. Clin. Pathol. 1980; 33, 167-170). This esterolytic determination method is imprecise and expensive and it is the does not do justice to actual in vivo reactions of the enzyme.
Weiters ist eine Bestimmungsmethode aufgrund der amidolytischen Wirkung der C1-Esterase bekannt, u.zw. aus "Thrombosis Research", Vol. 18, No. 6, 847-859 (1980).Another method of determination is based on the amidolytic effect the C1 esterase known, u.zw. from "Thrombosis Research", Vol. 18, No. 6, 847-859 (1980).
Bei dieser Methode wird die C1-Esterase-hältige Probe mit einem chromogenen Substrat auf Tripeptid-Basis umgesetzt und die Extinktion des abgespaltenen Chromophors (p-Nitroanilin) auf spektrophotometrischem Weg bestimmt.In this method, the C1-esterase-containing sample is mixed with a chromogenic The tripeptide-based substrate is converted and the extinction of the cleaved chromophore (p-nitroaniline) determined by spectrophotometric means.
Mit dieser Methode läßt sich jedoch der klinisch relevante C1-Esterase-Inhibitor-Gehalt nicht erfassen, weil mit und ohne Inhibitor-Zusatz das gleiche Meßergebnis gefunden wird. Dies ist auf die Sequenz und Raumstruktur des dort eingesetzten chromogenen Substrates zurückzuführen.With this method, however, the clinically relevant C1 esterase inhibitor content can be determined do not record because the same measurement result was found with and without the addition of an inhibitor will. This is due to the sequence and spatial structure of the chromogenic used there Substrate.
Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten der bisherigen Bestimmungsmethoden und stellt sich die Aufgabe, die Aktivität bzw. den Gehalt von C1-Esterase-Inhibitor in menschlichen oder tierischen Körperflüssigkeiten zuverlässig festzustellen.The invention aims to avoid these disadvantages and difficulties the previous determination methods and the task is to determine the activity or the level of C1 esterase inhibitor in human or animal body fluids reliable to determine.
Diese Aufgabe wird erfindungsgemäß durch Einsatz von Substraten gelöst, welche bestimmte chromogene Verbindungen auf Basis von Di-, Tri- oder Tetrapeptiden mit chromophoren oder fluoreszierenden Gruppen enthalten.This object is achieved according to the invention by using substrates which specific chromogenic compounds based on di-, tri- or tetrapeptides with chromophoric or fluorescent groups.
Das erfindungsgemäße Verfahren zur Bestimmung der C1 Esterase-Inhibitor-AktiviSt ist dadurch gekennzeichnet, daß die C1-Esterase-Aktivität der zu vergleichenden Präparat ionen durch spektrophotometrische Untersuchung von Spaltprodukten chromogener Verbindungen der allgemeinen Formel R1 - A - B - NH - R oder deren Säureadditionssalzen festgestellt wird, in welcher Formel R1 für Wasserstoff, Alkyl, einen Sulfonylrest, insbesondere Benzolsulfonyl oder p-Methoxybenzolsulfonyl (Mbs) oder einen Acylrest, insbesondere Alkoxycarbonyl, wie tert. Butyloxycarbonyl, Benzyloxycarbonyl oder Formyl, A für eine Aminosäurekomponente, einen Di- oder einen Tripeptidrest, B für eine der folgenden Aminosäurekomponenten: D-Arg, L-Arg, D-Lys, L-Lys, D-Orn, L-Orn, D-Tyr oder L-Tyr, D-Ala oder L-Ala,und -NH-R für eine chromophore oder fluoreszierende Gruppe stehen.The method according to the invention for determining the C1 esterase inhibitor activity is characterized in that the C1 esterase activity to be compared Preparations by spectrophotometric analysis of chromogenic cleavage products Connections of general Formula R1 - A - B - NH - R or their Acid addition salts, in which formula R1 for hydrogen, alkyl, a sulfonyl radical, in particular benzenesulfonyl or p-methoxybenzenesulfonyl (Mbs) or an acyl radical, especially alkoxycarbonyl, such as tert. Butyloxycarbonyl, benzyloxycarbonyl or formyl, A for an amino acid component, a di- or a tripeptide residue, B for one of the following amino acid components: D-Arg, L-Arg, D-Lys, L-Lys, D-Orn, L-Orn, D-Tyr or L-Tyr, D-Ala or L-Ala, and -NH-R for a chromophoric or fluorescent Standing group.
Vorteilhaft werden neue chromogene Verbindungen verwendet, worin R1 für Alkyl mit 1 bis 4 Kohlenstoffatomen oder für p-Methoxybenzolsulfonyl (Mbs) steht.New chromogenic compounds are advantageously used in which R1 represents alkyl having 1 to 4 carbon atoms or represents p-methoxybenzenesulfonyl (Mbs).
