Es sind sowohl bereits Naturstoffe als auch eine Reihe von Derivaten des 6,7-Dioxycumarins und insbesonders basische Äther des 4-Methyl-6,7-dioxycumarins bekannt, die eine Vitamin-P-Wirkung besitzen. Diese Stoffe bewirken somit eine Erhöhung der Kapillarresistenz, und sie können daher zur Behandlung von Krankheiten benutzt werden, die eine Verminderung der Kapillarresistenz verursachen.There are already natural products as well as a number of derivatives of 6,7-dioxycoumarins and In particular, basic ethers of 4-methyl-6,7-dioxycoumarins are known, which have a vitamin P effect own. These substances thus cause an increase in capillary resistance, and they can therefore be used Treatment of diseases that cause a decrease in capillary resistance.
Es wurde nun gefunden, daß basische Äther des 4-Methyl-5,7-dioxycumarins der allgemeinen FormelIt has now been found that basic ethers of 4-methyl-5,7-dioxycoumarins of the general formula
in der R eine gerad- oder verzweigtkettige, 1 bis 4 Kohlenstoffatome enthaltende Alkylengruppe bedeutet, bzw. deren Salze im Vergleich zu den bekannten Substanzen mit kapillardichtenden Eigenschaften eine erhöhte Vitamin-P-Wirkung aufweisen.in which R is a straight or branched chain alkylene group containing 1 to 4 carbon atoms, or their salts compared to the known substances with capillary sealing properties have an increased vitamin P effect.
Die überlegene Vitamin-P-Wirkung der Verfahrensprodukte wurde in Vergleichsversuchen gegenüber
bekannten Verbindungen ermittelt. Nach der Methode von A. L. Bachrach und Mitarbeitern (The
Biochemical Journal, Bd. 36, 1942, S. 407) wurde bei Meerschweinchen am Ende einer dreiwöchigen
skorbutartigen Diät der Ausgangswert der Kapillarresistenz mit Hilfe der Saugmethode bestimmt.
Hierbei wurde am Rücken des Tieres durch eine Vakuumpumpe ein Sog erzeugt und mit einem
Manometer der Druck gemessen. Als Ausgangswert wurde der Unterdruck (in mm Hg) festgelegt, der
Verfahren zur Herstellung von basischen Äthern
des 4-Methyl-5,7-dioxycumarinsThe superior vitamin P effect of the process products was determined in comparative tests with known compounds. According to the method of AL Bachrach and colleagues (The Biochemical Journal, Vol. 36, 1942, p. 407), the initial value of capillary resistance was determined in guinea pigs at the end of a three-week scurvy-like diet using the suction method. A vacuum pump was used to generate suction on the animal's back and the pressure was measured with a manometer. The initial value was the negative pressure (in mm Hg), the process for the production of basic ethers
of 4-methyl-5,7-dioxycoumarins

die Kapillarresistenz übertraf und das Auftreten einer hämorrhagischen Petechie auf dem Rücken des Meerschweinchens hervorrief. Den Tieren wurden die zu prüfenden Verbindungen als Chlorhydrate in wäßriger Lösung durch Intubation an drei aufeinanderfolgenden Tagen mit einer täglichen Dosis von 0,0003 Mol/kg pro Tier verabreicht. 12 Stunden nach der letzten Verabreichung wurde dann der Wert des Unterdruckes, der das Auftreten der Petechie auf dem Rücken des Tieres hervorgerufen hatte, wieder bestimmt. Die sich ergebende Druckdifferenz stellt das Maß für die kapillardichtende Wirkung dar. Die erhaltenen Ergebnisse sind in der folgenden Tabelle als prozentuale Veränderung angegeben.exceeded capillary resistance and the appearance of hemorrhagic petechia on the back of the guinea pig. The compounds to be tested were given to the animals as hydrochloric acid in aqueous solution by intubation for three consecutive days with a daily dose of 0.0003 mol / kg per animal administered. Then, 12 hours after the last administration, the value became the negative pressure that had caused the appearance of the petechia on the animal's back certainly. The resulting pressure difference is the measure of the capillary sealing effect The results obtained are shown in the table below as the percentage change.
