Es wurde gefunden, daß diese Verbindungen starke Wirkungen auf das zentrale und vegetative Nervensystem besitzen. Die Wirkungen auf das zentrale Nervensystem sind dämpfender Natur, und sie wurden gegenüber bekannten Verbindungen im Barbituratpotenzierungstest nach der von H 0 lt e n und L a r s e n in »Acta pharmacologica et toxicologica«, 12 (1956), S. 346 bis 363, beschriebenen Methode ermittelt. Hierbei wurde die zu prüfende Substanz in einer Dosis von 5010 der DL50 an weiße Mäuse subcutan verabreicht, nach einer halben Stunde den Tieren 100 mg 5-(cyclohexen-1-yl)-5-methyl-N-methylbarbitursaures Natrium appliziert und im Vergleich zu mit der Prüfsubstanz nicht vorbehandelten Tieren die Dauer des Schlafes gemessen. It has been found that these compounds have potent effects on the central and autonomic nervous systems. The effects on the central nervous system are of a depressant nature and were tested against known compounds in the barbiturate potentiation test according to that of H 0 lt e n and L a r s e n in "Acta pharmacologica et toxicologica", 12 (1956), pp. 346 to 363, described method determined. This became the test substance administered subcutaneously to white mice in a dose of 5010 of the DL50, after half an hour the animals received 100 mg of 5- (cyclohexen-1-yl) -5-methyl-N-methylbarbituric acid Sodium applied and compared to that which had not been pretreated with the test substance Animals measured the duration of sleep.
Die erhaltenen Ergebnisse sind in der folgenden Tabelle 1 zusammengestellt.

Aus den gefundenen Werten, wobei die positiven Zahlen eine Schlafverlängerung und die negative Zahl eine Schlafverkürzung bedeuten, geht hervor, daß die geprüften Verfahrensprodukte eine wesentlich bessere dämpfende Wirkung besitzen als die bekannten Verbindungen. From the values found, the positive numbers being a sleep extension and the negative number means a reduction in sleep, it can be seen that the tested Process products have a much better dampening effect than the known ones Links.
Außerdem zeigen beispielsweise die Substanzen II und III im Gegensatz zu den aus der USA.-Patentschrift 3 072650 bekannten Verbindungen einen beachtlichen adrenolytischen Effekt. Die adrenolytischen Werte wurden im Magnus-Bad an der isolierten Meerschweinchen-Samenblase gemessen (Methode von J. B r ü g g e r in »Helvetica physiologica acta«, 3, S. 117 bis 134 [1945], beschrieben) und als EDso-Werte graphisch ermittelt. Hierbei bedeutet der EDso-Wert diejenige Menge Substanz, welche die an der isolierten Meerschweinchen-S amenblase durch 1,6 y Adrenalin pro Kubikzentimeter Bad ausgelöste Kontraktion um 50°/o herabsetzt. In addition, for example, the substances II and III show in contrast to the compounds known from US Pat. No. 3,072,650 adrenolytic effect. The adrenolytic values were measured in the Magnus bath on the isolated Guinea pig seminal vesicle measured (method by J. B rü g ge r in »Helvetica physiologica acta «, 3, pp. 117 to 134 [1945]) and as ED 50 values determined graphically. The ED 50 value means the amount of substance which the isolated guinea pig semen vesicle by 1.6 y adrenaline per Cubic centimeter bath reduces the induced contraction by 50 per cent.
