Abstract
Description
Die vorliegende Erfindung betrifft Verbindungen sowie pharmazeutische Zusammensetzungen, die sowohl Dipetidyl Peptidase (insbesondere DPPIV) als auch Neurale Endopeptidase (NEP) inhibieren. Diese Verbindungen sowie pharmazeutische Zusammensetzungen sind insbesondere bei der Behandlung sowie der Prävention von Diabetes mellitus Typ II von Interesse.The present invention relates to Compounds, as well as pharmaceutical compositions, both Dipetidyl peptidase (especially DPPIV) as well as neural endopeptidase Inhibit (NEP). These compounds as well as pharmaceutical compositions are particularly in the treatment and prevention of type II diabetes of interest.
Diabetes mellitus, umgangssprachlich auch "Zuckerkrankheit" genannt, ist eine chronische Stoffwechselerkrankung. Etwa 3-5% der Bevölkerung in den Industriestaaten leidet an dieser Krankheit, in Deutschland allein etwa 6 Mio. Menschen. Damit zählt sie zu den häufigsten Krankheiten. Bei nicht optimaler Therapieführung sind es vor allem die Folgeschäden der Zuckerkrankheit, die für den Patienten eine dramatische Beeinträchtigung der Lebensqualität bedeuten. Zu diesen Folgeschäden des Diabetes mellitus zählen Sehverlust, Nierenversagen, Störungen am Nervensystem sowie eine erhöhte Anfälligkeit für Herzinfarkt, Schlaganfall und Durchblutungsstörungen der Beine. Studien an großen Patienten-Kollektiven haben gezeigt, daß durch eine Normalisierung des Blutzuckers das Auftreten von Folgeschäden der Zuckerkrankheit vermeidbar ist. Man unterscheidet zwei Typen von Diabetes mellitus: Diabetes mellitus Typ I (Insulin-abhängige Diabetes) und Diabetes mellitus Typ II (Nicht-Insulin-abhängige Diabetes, Altersdiabetes). Bei Menschen, die unter Typ II Diabetes leiden (etwa 95% aller Diabetiker) gibt die Bauchspeicheldrüse zu wenig, oder nicht im richtigen Zeitverlauf Insulin ins Blut ab, bzw. das Insulin entfaltet nicht seine Wirkung ("Insulin-resistenz"). Die Normalisierung ihres Blutzuckerspiegels erfolgt durch Insulin, Orale Antidiabetika und/oder Sport und Diät. Diese Therapiemethoden sind jedoch nicht optimal ausgelegt, um den Blutzuckerspiegel in den natürlichen Grenzen zu halten, was für den Patienten eine dramatische Beeinträchtigung der Lebensqualität zur Folge hat.Diabetes mellitus, colloquially also called "diabetes" is one chronic metabolic disease. About 3-5% of the population this disease suffers in the industrialized countries, in Germany alone about 6 million people. So that counts them the most common Diseases. If the therapy is not optimal, it is primarily that consequential damages the diabetes that is for mean a dramatic deterioration in the quality of life for the patient. About these consequential damages of diabetes mellitus Vision loss, kidney failure, disorders on the nervous system as well as an increased susceptibility for heart attack, Stroke and circulatory disorders of the legs. Studies on large Patient collectives have shown that normalization of blood sugar the occurrence of consequential damage to diabetes can be avoided is. There are two types of diabetes mellitus: diabetes Type I mellitus (insulin-dependent Diabetes) and type II diabetes (non-insulin-dependent diabetes, Adult-onset diabetes). In people who have type II diabetes (about 95% of all diabetics) don’t give enough pancreas, or does not release insulin into the blood or the insulin in the right time does not develop its effect ("insulin resistance"). The normalization Your blood sugar level is caused by insulin, oral antidiabetic drugs and / or sports and diet. However, these therapy methods are not optimally designed to the Blood sugar levels in the natural Keep boundaries what for result in a dramatic deterioration in the quality of life for the patient Has.
Die wichtigsten Alternativen, für die Behandlung von Diabetes mellitus Typ II, die derzeit erprobt werden, stellen Verbindungen dar, die den Abbau der Peptidhormone GLP-1 ("Glucagon-Like Peptide") und GIP (Glucose-Dependent Insulinotropic Peptide") inhibieren. Diese Hormone, die auch Incretine genannt werden, haben Rezeptoren auf der Oberfläche von Insulin-produzierenden Zellen der Bauchspeicheldrüse. Diese Zellen besitzen auch Glucoserezeptoren. Erst wenn beide Rezeptortypen ihre jeweiligen Liganden binden, wird in den Zellen eine Signalkaskade ausgelöst, die zur Freisetzung von Insulin führt. Zur Insulinfreisetzung werden also zwei Signale benötigt: Glucose und die Incretine; wenn eines der beiden Signale fehlt, wird kein Insulin ausgeschüttet. Die Halbwertszeit der Incretine beträgt nur wenige Minuten. Für diesen Abbau ist das Enzym Dipeptidylpeptidase IV (DPP IV) verantwortlich. In Tierversuchen an diabetischen Ratten konnte gezeigt werden, daß eine Verlängerung der Halbwertzeit der Incretine die Insulin-ausschüttung wieder normalisiert.The main alternatives for treatment of type II diabetes mellitus that are currently being tested Compounds representing the breakdown of the peptide hormones GLP-1 ("Glucagon-Like Peptide") and GIP (Glucose-Dependent Insulinotropic Inhibit peptides "). These hormones, also called incretins, have receptors on the surface of insulin-producing cells of the pancreas. This Cells also have glucose receptors. Only when both types of receptors bind their respective ligands, a signal cascade becomes in the cells fires which leads to the release of insulin. For insulin release two signals are required: Glucose and the incretins; if one of the two signals is missing, no insulin is released. The half-life of the incretins is only a few minutes. For this Degradation is caused by the enzyme dipeptidyl peptidase IV (DPP IV). Animal tests on diabetic rats have shown that an extension normalized the insulin release during the half-life of the incretins.
Seit einiger Zeit gibt es Hinweise, das Inhibitoren von Neuraler Endopeptidase (NEP) ebenfalls antidiabetische Wirkung aufweisen (Sodmann et al, Regul. Pept., 1995, 149; Peptides, 1997, 625). Aus diesem Grund sind pharmazeutische Zusammensetzungen, die sowohl einen oder mehrere DPP IV Inhibitoren als auch einen oder mehrere NEP Inhibitoren enthalten von Interesse. Des weiteren sind Verbindungen, die sowohl DPP IV als auch NEP inhibieren von grossem Interesse.For some time there have been indications the inhibitors of neural endopeptidase (NEP) are also anti-diabetic Have effect (Sodmann et al, Regul. Pept., 1995, 149; Peptides, 1997, 625). For this reason, pharmaceutical compositions which are both one or more DPP IV inhibitors and one or contain several NEP inhibitors of interest. Furthermore are compounds that inhibit both DPP IV and NEP of great interest.
