Derivaterne af formlen IV har vigtige antiarhytmiske egenskaber.The derivatives of formula IV have important antiarrhythmic properties.

Forsøgene udført med kaniner og hunde efter fremgangsmåden ifølge H. Schmitt og H. Schmitt [Arch. Int. Pharmacodyn., 1960, 127 (1,2)3 har vist, at en oral dosis på 5 mg/kg af derivaterne nr. 31-39 og 61-63 fuldstændigt beskyttede forsøgsdyrene mod arhytmia induceret af administration af bariumklorid.The experiments performed with rabbits and dogs following the method of H. Schmitt and H. Schmitt [Arch. Int. Pharmacodyn., 1960, 127 (1,2) 3 has shown that an oral dose of 5 mg / kg of derivatives Nos. 31-39 and 61-63 completely protected the test animals against arrhythmia induced by administration of barium chloride.

Der er ingen regelmæssige eller spredte ekstrasystole udbrud hos de beskyttede dyr.There are no regular or scattered extrasystole outbreaks in the protected animals.

Samme hæmning findes også med hensyn til andre arhytmiafrem-kaldende midler såsom kalciumklorid, K-strofantin, aconitin, isoprenalin, adrenalin og ouabain.The same inhibition is also found for other arrhythmia-inducing agents such as calcium chloride, K-strophantine, aconitine, isoprenaline, adrenaline and ouabain.

De antiarhytmiske egenskaber af forbindelserne af formlen IV blev også undersøgt på en anden måde. Rytmeuregelmæssigheder blev frembragt på hunde ved underbinding af en coronararterie.The antiarrhythmic properties of the compounds of formula IV were also investigated in a different way. Rhythmic irregularities were produced on dogs by the binding of a coronary artery.

Følgende tabel viser de"kvantitative resultater af forsøg med 6 hunde. En dosis på 10mg/kg af derivat nr. 31 administreres til hunden ca. 20 timer efter underbindingen på tidspunktet 0. Hjerterytmen iagttages hver time i 6 timer, og resultaterne anføres i procent af sinuskomplekserne (θ% = fuldstændig arhytmi, 100% - normalt hjerte.) nr. underbinding Tid 0 lh 2h 3h 4h 5h 6h 1 +21h 15 14 0 91 94 100 43 57 2 +22h 20 0 32 70 74 68 60 52 3 +22h 20 9 0 16 75 100 59 9 4 +20h 11 45 83 80 75 50 22 5 +19h 7 0 55 87 94 36 11 6 +20h 30 10 21 63 100 38 30 28The following table shows the "quantitative results of experiments with 6 dogs. A dose of 10mg / kg of derivative # 31 is administered to the dog approximately 20 hours after the binding at time 0. Heart rate is observed every hour for 6 hours and results are given in percent. of the sinus complexes (θ% = complete arrhythmia, 100% - normal heart.) no binding Time 0 lh 2h 3h 4h 5h 6h 1 + 21h 15 14 0 91 94 100 43 57 2 + 22h 20 0 32 70 74 68 60 52 3 + 22h 20 9 0 16 75 100 59 9 4 + 20h 11 45 83 80 75 50 22 5 + 19h 7 0 55 87 94 36 11 6 + 20h 30 10 21 63 100 38 30 28

Det blev vist, at administration af et derivat af formlen IV var i stand til at genoprette sinusrytmen og at forbedre den forstyrrede elektriske aktivitet af hjertet ved at genskabe en rytmisk ventri-kulær aktivitet.It was shown that administration of a derivative of formula IV was able to restore the sinus rhythm and improve the disturbed electrical activity of the heart by restoring a rhythmic ventricular activity.
