Description

Verfahren zur Herstellung von Derivaten des 7-Oxychromons Es wurde gefunden, daß Derivate des 7-Oxychromons der allgemeinen Formel in der R einen niedrigen Alkylrest mit 1 bis 4 Kohlenstoffatomen oder den Allylrest bedeutet und der Alkylenrest aus I bis 4 Kohlenstoffatomen besteht, eine sehr gute gefäßerweiternde Wirkung, insbesondere auf die Coronargefäße, besitzen und in dieser Hinsicht gegenüber bekannten Stoffen überlegen sind.Process for the preparation of derivatives of 7-oxychromone It has been found that derivatives of 7-oxychromone of the general formula in which R denotes a lower alkyl radical with 1 to 4 carbon atoms or the allyl radical and the alkylene radical consists of 1 to 4 carbon atoms, have a very good vasodilating effect, especially on the coronary vessels, and are superior to known substances in this regard.

Sie eignen sich daher hervorragend zur Behandlung von Spasmen, insbesondere der Coronargeiäße.They are therefore great for treating spasms, in particular the coronary vessels.

Die Coronarwirksamkeit wurde in Vergleichsversuchen nach der von Eckenhoff, Hafkenschiel und Eandmesser im American Journal of Physiology, 148, (1947) S. 582, beschriebenen Methode am Hund gegenüber Papaverin, dem aus der deutschen Auslegeschrift 1 055 544 bekannten Flavon-7-oxyäthylacetat und dem aus der deutschen Auslegeschrift 1 054 091 bekannten 7-(N-y-Dimethylaminopropoxy)-flavon geprüft. Hierbei wurde den narkotisierten Tieren die zu prüfende Verbindung intracoronar appliziert, die Corona durchblutung wurde mittels einer automatisch arbeitenden Bubble-Flow-Stromuhr gemessen und der Blutdruck mit einem Anderson-Glass-Capsule-Manometer registriert. Während der Versuchsdauer wurden die Tiere künstlich beatmet. Bei dieser Versuchsanordnung führte eine durch die betreffende Substanz hervorgerutene Erweiterung der Coronararterie zu einem schnelleren Blasenumlauf, während sich eine Verengung der Herzkranzgefäße in einer Verlangsamung des Blasenumlaufs anzeigte. Die Änderungen wurden jeweils auf einem Kymographen registriert. The coronary effectiveness was in comparative tests according to that of Eckenhoff, Hafkenschiel and Eandmesser in the American Journal of Physiology, 148, (1947) P. 582, described method on the dog compared to Papaverin, the one from the German Auslegeschrift 1 055 544 known Flavon-7-oxyäthylacetat and that from the German Auslegeschrift 1,054,091 known 7- (N-y-dimethylaminopropoxy) -flavone tested. Here, the compound to be tested was intracoronary to the anesthetized animals applied, the corona blood circulation was by means of an automatically working Bubble flow electric meter measured and blood pressure with an Anderson-Glass-Capsule manometer registered. During the duration of the experiment, the animals were artificially ventilated. At this Experimental set-up resulted in an extension made through the substance in question The coronary artery causes more rapid bladder circulation while narrowing the coronary arteries showed a slowdown in the circulation of the bladder. The changes were each recorded on a kymograph.

Als Standardvergleichspräparat wurde bei jedem neuen Versuch Papaverin mitgeprüft. Da die für die Versuchspräparate gefundenen Meßwerte wegen der verschiedenen Ansprechbarkeit der Versuchstiere nicht unmittelbar miteinander vergleichbar sind, sondern nur über die ermittelten zugehörigen Papaverinwerte, ist es erforderlich, vor der Prüfung des Versuchspräparats jeweils den Standardwert für Papaverin festzustellen. Um die Wirksamkeit des Flavon-7-oxyäthylacetats und des 7-(N-y-Dimethylaminopropoxy)-flavons zu ermitteln, wurden diese Präparate jeweils ebenfalls gegenüber Papaverin als Vergleichspräparat geprüft. In der nachfolgenden Tabelle sind die bei den Vergleichsversuchen erhaltenen Ergebnisse zusammengefaßt.

Since the measured values found for the test preparations cannot be directly compared with one another because of the different responsiveness of the test animals, but only via the associated papaverine values determined, it is necessary to determine the standard value for papaverine in each case before testing the test preparation. In order to determine the effectiveness of the flavone 7-oxyäthylacetats and the 7- (Ny-dimethylaminopropoxy) -flavone, these preparations were each also tested against papaverine as a comparison preparation. The results obtained in the comparative experiments are summarized in the table below.

Aus den gefundenen Werten geht hervor, daß das 2 - Methyl - 3- phenyl - chromon - 7 - oxyäthylacetat in gleicher Dosierung wie die bekannten Mittel eine fast gleich starke Coronardurchblutung wie die bekannten Präparate bewirkt, die jedoch länger anhält als die der bekannten Verbindungen und wobei das neue 2-Methyl-3-phenylchromon-7-oxyäthylacetat eine bedeutend geringere Toxizität als die bekannten Verbindungen besitzt. The values found show that the 2-methyl-3-phenyl - chromon - 7 - oxyäthylacetat in the same dosage as the known means one causes almost the same strong coronary blood flow as the known preparations that but lasts longer than that of the known compounds and the new 2-methyl-3-phenylchromone-7-oxyethyl acetate has a significantly lower toxicity than the known compounds.

Die Derivate des 7-Oxychromons der oben angegebenen allgemeinen Formel werden erfindungsgemäß dadurch hergestellt, daß man 2-Methyl-3-phenyl-7-oxychromon in an sich bekannter Weise mit Halogenverbindungen der allgemeinen Formel Hal - alkylen - COOR in der Hal ein Halogenatom darstellt und R die oben angegebene Bedeutung besitzt, in Gegenwart eines säurebindenden Mittels umsetzt.

Beispiel 2-Methyl-3-phenyl-chromon-7-oxyäthylacetat Eine Mischung aus 21 g 2-Methyl-3-phenyl-7-oxychromon, 10,5 g Chloressigsäureäthylester, 9 g wasserfreiem Kaliumkarbonat und 400 ccm Aceton wird 7 Stunden unter Rühren am Rückfluß erhitzt. Example 2-methyl-3-phenyl-chromone-7-oxyethyl acetate A mixture from 21 g of 2-methyl-3-phenyl-7-oxychromone, 10.5 g of ethyl chloroacetate, 9 g of anhydrous Potassium carbonate and 400 cc of acetone are refluxed with stirring for 7 hours.

Dann läßt man das erhaltene Reaktionsgemisch erkalten, saugt vom ausgeschiedenen Kaliumchlorid ab und wäscht mit Aceton nach. Das Acetonffltrat wird vom Lösungsmittel befreit, der verbleibende Rückstand mehrfach mit Wasser verrieben, jeweils abgesaugt und schließlich im Vakuum getrocknet. The reaction mixture obtained is then allowed to cool, and is sucked off precipitated potassium chloride and washed with acetone. The acetone filtrate is freed from the solvent, the remaining residue triturated several times with water, each suctioned off and finally dried in a vacuum.

Der hierbei erhaltene Rückstand wird anschließend aus Alkohol umkristallisiert. Man erhält das 2-Methyl-3-phenylchromon-7oxyäthylacetat vom F. 111 bis 112"C. Die Ausbeute beträgt 23,5 g.The residue obtained in this way is then recrystallized from alcohol.
