Abstract
The invention concerns the use of 8-(3-oxocyclopentyl)-1,3-dipropyl-7H-purine-2,6-dione.
Description
Verwendung von 8-(3-Oxocvclopentyl)- 1.3-dipropyl-7H-purin-2.6-dion zur symptomatischen Behandlung der zvstischen Fibröse Use of 8- (3-oxocclopentyl) - 1,3-dipropyl-7H-purine-2,6-dione for the symptomatic treatment of the fibrous nerve
Die vorliegende Erfindung betrifft die Verwendung von 8-(3-θxocyclopentyl)-1,3-dipropyl-7H-purin-2,6-dion insbesonere in R(+)-8-(3-Oxocyclopentyl)-1,3-dipropyl- 7H-purin-2,6-dion seines (-)-Enantiomeren und Strukturähnliche Verbindung zur symptomatischen Behandlung der zystischen Fibröse.The present invention relates to the use of 8- (3-θxocyclopentyl) -1,3-dipropyl-7H-purine-2,6-dione in particular in R (+) - 8- (3-oxocyclopentyl) -1,3-dipropyl - 7H-purine-2,6-dione of its (-) - enantiomer and structure-like compound for the symptomatic treatment of cystic fibrosis.
Die zystische Fibröse - auch als Mukoviszidose bekannt - ist eine erbliche StoffWechselstörung, hervorgerufen durch einen genetischen Defekt eines bestimmten Chromosoms. Nur homocygote Merkmalträger erkranken. Der genetische Defekt führt zu einer Dysfunktion exokriner Drüsen. Durch eine vermehrte Produktion und erhöhte Viskosität des Sekrets der mukösen Drüsen in den Bronchien kann es zu schweren Komplikationen im Bereich der Atemwege kommen. Erste Untersuchungen haben gezeigt, daß in A.-Antagonisten den Efflux von Chloridionen von CF PAC Zellen erhöhen. Die Zellen entstammen einer pankreas adenocarcinoma Zellinie, die von an cystischer Fibröse (CF) erkrankten Patienten isoliert wurde. Die Wirkung des Xanthins konnte durch Agonisten, wie z.B. 2-Chloradenosin blockiert werden. Interessanterweise wurde eine Erhöhung des Effluxes nur bei solchen Zellen beobachtet, die von an cystischer Fibröse erkrankten Patienten stammten.Cystic fibrosis - also known as cystic fibrosis - is an inherited metabolic disorder caused by a genetic defect in a particular chromosome. Only homozygous traits become ill. The genetic defect leads to dysfunction of exocrine glands. Increased production and increased viscosity of the secretions of the mucous glands in the bronchi can lead to serious complications in the area of the respiratory tract. Initial studies have shown that in A. antagonists the efflux of chloride ions from CF PAC cells increases. The cells originate from a pancreatic adenocarcinoma cell line which was isolated from patients suffering from cystic fibrosis (CF). The action of the xanthine could be reduced by agonists, e.g. 2-chloroadenosine can be blocked. Interestingly, an increase in efflux was only observed in cells from patients with cystic fibrosis.
Ausgehend von diesen Befunden kann erwartet werden, daß bei Patienten die an Mukoviszidose erkrankt sind, der gestörte Elektrolythaushalt der Zellen reguliert und die Symptome der Erkrankung gemildert werden. Von besonderem Interesse ist das 8-(3-0xocyclopentyl)-l,3-
dipropyl-7H-purin-2,6 dion-wie auch das optisch aktiveBased on these findings, it can be expected that in patients with cystic fibrosis, the disturbed electrolyte balance of the cells can be regulated and the symptoms of the disease can be alleviated. Of particular interest is 8- (3-0xocyclopentyl) -l, 3- dipropyl-7H-purine-2,6 dione as well as the optically active
R(+)-8-(3-θxocyclopentyl)-1,3-dipropyl-7H-purin-2,6-dion,da aufgrund seiner selektiven hohen A -antagonisti¬ schen Wirkung und seiner unerwartet guten Wasser¬ löslichkeit in vivo allen anderen bisher bekannten Al-Adenosin-Rezeptor- Antagonisten überlegen ist7 Die Verbindung selbst, wie auch ihre pharmakologische Wirkung als Therapeutikum zur symptomatischen Behandlung degenerativer Alterserkrankungen, ist aus der Europäischen Patentanmeldung 374 808 beschrieben. Die Herstellung der Verbindung - auch als R(+)-l,3-Dipropyl-8- (3-oxocyclopentyl)-xanthin bezeichnet - erfolgt nach an sich bekannten Verfahren, wie z.B. in den Beispielen 2a, 2b und 16 der genannten Patentanmeldung, auf die hiermit inhaltlich Bezug genommen wird.R (+) - 8- (3-θxocyclopentyl) -1,3-dipropyl-7H-purine-2,6-dione, because of its selective high A -antagonistic effect and its unexpectedly good water solubility in vivo, all is superior to other previously known Al-adenosine receptor antagonists7 The compound itself, as well as its pharmacological action as a therapeutic agent for the symptomatic treatment of degenerative aging diseases, is described in European patent application 374 808. The preparation of the compound - also referred to as R (+) - 1,3-dipropyl-8- (3-oxocyclopentyl) xanthine - takes place according to processes known per se, such as e.g. in Examples 2a, 2b and 16 of the cited patent application, to which reference is hereby made.
Geeignete Strukturähnliche Xanthin-Derivate sind auch in den Europäischen Patentanmeldungen 374 808 und 487 673 beschrieben, auf die hiermit ausdrücklich Bezug genommen wird, insbesondere auf die dort als bevorzugt beschriebenen Bereiche und Ausführungsbeispiele.Suitable structurally similar xanthine derivatives are also described in European patent applications 374 808 and 487 673, to which reference is hereby expressly made, in particular to the areas and exemplary embodiments described as preferred there.
Von Interesse sind daher auch Xanthine der allgemeinen FormelXanthines of the general formula are therefore also of interest
