Description
Kreislaufbeeinflussende Mittel Die vorliegende Erfindung betrifft die Verwendung von teilweise bekannten 1,4-Dihydropyridinen als Kreislaufmittel insbesondere als Coronarmittel. Circulatory Agents The present invention relates to the use of some known 1,4-dihydropyridines as circulatory agents especially as a coronary agent.
1,4-Dihydropyridine und Verfahren zu ihrer Herstellung sind bereits bekannt geworden. Ihre Verwendung als Arzneimittel insbesondere als Coronarmittel wurde jedoch bisher nicht beschrieben.1,4-Dihydropyridines and processes for their preparation are already in place known. Their use as pharmaceuticals, in particular as coronary drugs however, it has not yet been described.
Es wurde gefunden, daß die teilweise bekannten 1,4-Dihydropyridine der Formel in welcher R für eine Alkylgruppe mit 1-3 C-Atomen, R? für eine Alkylgruppe mit 1 - 4 C-Atomen und R11 für einen Nitro- oder Aminorest steht oder für zwei Substituenten steht wobei einer der Substituenten wieder 1-Nitro- oder Aminorest ist und der zweite Substituent ein Rest aus der Gruppe Nitro, Amino, Halogen oder Dialkylamino mit 1 - 2 C-Atomen im Alkylrest ist, starke Coronarwirkung zeigen.It has been found that the partially known 1,4-dihydropyridines of the formula in which R for an alkyl group with 1-3 carbon atoms, R? stands for an alkyl group with 1-4 carbon atoms and R11 stands for a nitro or amino radical or stands for two substituents, one of the substituents again being 1-nitro or amino radical and the second substituent being a radical from the group consisting of nitro, amino, halogen or dialkylamino with 1 - 2 C atoms in the alkyl radical, show strong coronary effects.
Unter den Erkrankungen des Kreislaufes nehmen vor allem solche, die die Coronarien des Herzens betreffen immer mehr an Häufigkeit zu. Es hat daher nicht an Versuchen gefehlt wirksame Verbindungen zur Bekämpfung dieser Erkranlnuyyen aufzufinden.Among the diseases of the circulatory system, the most common ones are the coronaries of the heart concern more and more frequency. It has therefore not There is a lack of attempts to find effective compounds to combat these diseases.
Die bisher handelsublichen Präparate jedoch, z.B. Dipyramidol und Carbochromen, die nach den Tierexperimenten bei intravenöser Gabe therapeutische Hoffnungen berechtigt erscheinen ließen, haben bei der Coronarinsuffizienz besonders bei der schmerzhaften Angina pectoris, nicht immer'sichere klinische Erfolge gezeigt.However, the previously commercially available preparations, e.g. Dipyramidol and Carbochromes which, according to animal experiments, are therapeutic when given intravenously Have hopes appear justified, especially in the case of coronary insufficiency in painful angina pectoris, clinical success has not always been shown.
So war man in den meisten Fällen noch immer auf Nitrite, deren Wirkung unter anderem auf eine Herzentlastung beruht,angewiesen.So in most cases you were still on nitrites and their effects among other things, relies on cardiac relief.
Das ebenfalls als Coronartherapeutikum verwendete Nitroglycerin besitzt nur eine Wirkungsdauer von ca 5 Minuten und ist deshalb zur profilaktischen Behandlung von Coronarerkrankungen ungeeignet. überraschenderweise zeigen die erfindungsgemäßen 1,4-Dihydropyridine sowohl bei intravenöser Applikation als insbesondere auch bei der oraler Applikation eine deutliche und lang anhaltende Coronarerweiterung. Durch ihre starke Wirkung, ihren schnellen Wirkungseintritt, ihre lange Wirkungsdauer haben sich die erfindungsgemäßen Verbindungen allen bisher bekannten Handelsprodukten überlegen gezeigt.The nitroglycerin, which is also used as a coronary therapeutic agent, has only lasts about 5 minutes and is therefore for profilactic treatment unsuitable for coronary diseases. Surprisingly show the invention 1,4-Dihydropyridines both with intravenous administration and especially with Oral application results in a significant and long-lasting coronary enlargement. By their strong effects, their rapid onset of action, their long duration of action the compounds according to the invention have all previously known commercial products shown superior.
Darüber hinaus zeigen die erfindungsgemäßen Verbindungen einen sehr starken muskulotropen Calciumantagonismus. Dieser Wirkungsmechanismus der erfindungsgemäßen Verbindungen weicht von dem Wirkungsmechanismus der Vergleichssubstanzen ab. Somit stellen die erfindungsgemäßen coronarwirksamen Verbindungen eine Bereicherung der Pharmazie dar, weil sie einmal eine Überlegenheit gegenüber bekannten Substanzen zeigen und zum anderen ein weiteres Mittel mitandersartigemWirkungsmechanismus zur Behandlung von Coronarerkrankungen darstellen.In addition, the compounds according to the invention show a great deal strong musculotropic calcium antagonism. This mechanism of action of the invention Compounds deviates from the mechanism of action of the comparison substances. Consequently represent the coronary active compounds according to the invention one An enrichment of pharmacy because it once had an advantage over known ones Substances show and on the other hand another means with a different mechanism of action for the treatment of coronary diseases.
Die erfindungsgemäßen Verbindungen werden erhalten, indem man Benzaldehyde der Formel in welcher R" die obengenannte Bedeutung besitzt mit Acylfettsäureestern der Formel R-CO-CH2-COOR' III ifl welcher R und R' die obenangegebene Bedeutung besitzen und mit Ammoniak in einem organischen Lösungsmittel insbesondere A1koilol umsetzt.The compounds according to the invention are obtained by adding benzaldehydes of the formula in which R "has the abovementioned meaning with acyl fatty acid esters of the formula R-CO-CH2-COOR 'III ifl which R and R' have the meaning given above and, in particular, reacts alcohol with ammonia in an organic solvent.
Die aininosubstituierten Verbindungen werden auch durch Reduktion dar entsprechenden, auf dem obengenannten Wege gewonnenen Nitroverbindungen erhalten. einige der erfindungsgemäßen Wirkstoffe sind bekannt (vgl. auch Journ. Amer. Chem. Soc. 71 (1949), Seite 4003-4007 und Chem. Abstr. 60 (1964), Spalte 1689h-1690c).The amino substituted compounds are also reduced by reduction obtained from the corresponding nitro compounds obtained in the abovementioned route. some of the active ingredients according to the invention are known (cf. also Journ. Amer. Chem. Soc. 71 (1949), pp. 4003-4007 and Chem. Abstr. 60 (1964), columns 1689h-1690c).

Gleichzeitig mit der stark vermehrten Coronardurchblutung erfolgt eine Blutdrucksenkung, die zu einer Entlastung des Herzens führt. Eine solche periphere Widerstandßherabsetzung hat eine meßbare Sauerstoffverbrauchssenkung zur Folge. Hierin ähnelt der Stoff den bekanntlich klinisch sehr wirksamen SitritenF die ebenfalls eine feststellbare Sauerstoffverbrauchssenkung bewirken.Takes place at the same time as the greatly increased coronary blood flow a decrease in blood pressure that relieves the strain on the heart. Such a peripheral Resistance reduction has a measurable decrease in oxygen consumption result. In this respect, the substance is similar to the well-known, clinically very effective SitritenF which also cause a noticeable reduction in oxygen consumption.

Darüber hinaus ist zu bemerken, daß der Wirkungsmechanismus der erfindungsgemäßen Verbindungen von dem Wirkungsmechanismus der Vergleichssubstanz abweicht. So zeigen die erfindungsgemäßen Verbindungen im Vergleich zu Dipyridamole, welches keinen Calciumantagonismus aufweist, und zu allen bisher bekannten coronarwirksamen Verbindungen einen sehr starken muskulotropen Calciumantagqnismus. Damit stellen die erfidungsgemäßen Verbindungen nicht nur wegen ihrer überlegenen Wirkung, ihres schnellen Wirkungseintritts, ihrer langen Wirkungsdauer und ihrer sublingualen Resorption sondern auch auf Grund ihres neuartigen Wirkungsmechanismus insbesondere dem vorteilhaften Calciumantagonismus, eine Bereicherung der Pharmazie dar.In addition, it should be noted that the mechanism of action of the invention Compounds deviates from the mechanism of action of the reference substance. So show the compounds of the invention compared to Dipyridamole, which does not Has calcium antagonism, and to all previously known coronary active compounds a very strong musculotropic calcium antagonism. Thus represent the according to the invention Compounds not only because of their superior effect, their rapid onset of action, their long duration of action and their sublingual resorption but also because of their novel mechanism of action, in particular the beneficial calcium antagonism, an enrichment of pharmacy.
