Reaksjonstemperaturen kan variere mellom omtrent 0 og 80°G, men man arbeider hensiktsmessig ved romtemperatur. For påskyndelse av omsetningen kan det foretas omroring. Reaksjonsvarigheten avhenger selvfølgelig også av reaksj onstemperaturen. The turnover according to procedure a) takes place e.g. in the case of a solution of a compound of formula II and a compound of formula III in an organic solvent inert under the reaction conditions, e.g. a lower alkanol such as ethanol, and in the presence of a basic condensing agent, e.g. an alkali metal alcoholate such as potassium tert-butylate. The reaction temperature can vary between approximately 0 and 80°G, but it is appropriate to work at room temperature. Agitation can be done to speed up turnover. Of course, the reaction duration also depends on the reaction temperature.

Ved infusjonsforsok i narkotisert katt forer de ved doser på 0,02 til 0,6 mg/kg til en hemming av den ved isoproterenol betingede tachycardie og blodtrykkssenkning. Thus, the compounds show an inhibition of the positivinotropic adrenaline action on spontaneously beating, isolated guinea pig atria, this antagonistic action occurring at a bath concentration of 0.005 to 2.5 mg/l. In infusion trials in anesthetized cats, doses of 0.02 to 0.6 mg/kg lead to inhibition of isoproterenol-induced tachycardia and lowering of blood pressure.

de adrenergiske B-reseptorer. De kan folgelig blant annet anvendes for profylakse og terapi av koronarsykdommer, spesielt for the adrenergic B receptors. They can therefore, among other things, be used for the prophylaxis and therapy of coronary diseases, especially for

behandling av Angina-pectoris, for behandling av det hyperkinetiske hjertesyndrom og de fra en muskulær-hypertrofisk subvalvulær aortastenose resulterende tilstander. treatment of Angina pectoris, for the treatment of the hyperkinetic heart syndrome and those resulting from a muscular-hypertrophic subvalvular aortic stenosis.

Vanlig oppnås dog tilfredsstillende resultater med doser på omtrent 0,01 mg til 1,5 mg/kg kroppsvekt, og denne dose kan om nodvendig tilfores i 2 til *f deldoser eller også som retardform. For storre pattedyr ligger dagsdosen ved omtrent 2 til 100 mg. For orale tilførsler inneholder deldosene omtrent 0,5 til 50. mg av de nye forbindelser ved siden av faste eller flytende bærersubstanser eller -fortynningsmidler. For the above-mentioned application, the dose used naturally varies according to the compound used, the method of administration and the desired treatment. Usually, however, satisfactory results are achieved with doses of approximately 0.01 mg to 1.5 mg/kg body weight, and this dose can, if necessary, be administered in 2 to *f partial doses or also as a slow-release form. For larger mammals, the daily dose is approximately 2 to 100 mg. For oral administration, the partial doses contain about 0.5 to 50 mg of the new compounds in addition to solid or liquid carriers or diluents.

Forbindelsene fremviser videre interessante stoffskiftevirkninger. • Således bevirker de i isolerte fettceller av det epididymale fett-vev i rotter (metoden etter M.

Dosen kan tilfores i 2 til h deldoser eller også som retardform. For oral tilforsel inneholder deldosene omtrent 0,25 til 50 mg av de nye forbindelser ved siden For the above-mentioned application, the dose used naturally varies according to the compound used, the method of administration and the desired treatment. Usually, however, satisfactory results are obtained with doses of approximately 0.02 to 5 mg/kg body weight. For larger mammals, the daily dose is in the range from about 1 to 100 mg of the compound used. The dose can be given in 2 to 1 hour partial doses or also as a slow-release form. For oral administration, the partial doses contain approximately 0.25 to 50 mg of the new compounds at the side

Eksempel 38 : 1_ = (2=hyd.roksy=3 (2-metyl=3-b^tZ^Z2-yl-amino) - Example 38: 1_ = (2=hydroxy=3 (2-methyl=3-b^tZ^Z2-yl-amino) -

grogoksy)isokinolin (fremgangsmåte a)grogoxy)isoquinoline (method a)

0,86 g kalium loses i *f0 ml tert.butylalkohol og tilsettes 3 ?8 g 1 -(2-metyl-3-butynylamino)-2,3-dihydroksypropanol og deretter 0.86 g of potassium is dissolved in *f0 ml of tert.butyl alcohol and 3 ?8 g of 1 -(2-methyl-3-butynylamino)-2,3-dihydroxypropanol is added and then

3,6 g 1-klorisokinolin. Etter en dags omroring oppvarmes i ytterligere 1 dag ved 50°C. Reaksjonslosningen inndampes'under vakuum. Resten opptas i 1N saltsyre og eter, den vandige fase nøytraliseres med 2N sodalbsning og ekstraheres med metylenklorid. Etter torring over magnesiumsulfat og inndamping erholdes en olje som med fumarsyre i metylenklorid og eter gir bis-fumaratet av den i overskriften nevnte forbindelse med smeltepunkt 176 - 177°C. 3.6 g of 1-chloroisoquinoline. After stirring for one day, heat for a further 1 day at 50°C. The reaction solution is evaporated under vacuum. The residue is taken up in 1N hydrochloric acid and ether, the aqueous phase is neutralized with 2N sodium hydroxide solution and extracted with methylene chloride. After drying over magnesium sulfate and evaporation, an oil is obtained which, with fumaric acid in methylene chloride and ether, gives the bis-fumarate of the compound mentioned in the title with a melting point of 176 - 177°C.

Den anvendte 1 -(2-metyl-3-butynylamino)-2,3-dihydroksypropanol erholdes, ved omsetning av glycidol med ekvimolære mengder 2-amino-2-metyl-3-butyn i etanol. The 1-(2-methyl-3-butynylamino)-2,3-dihydroxypropanol used is obtained by reacting glycidol with equimolar amounts of 2-amino-2-methyl-3-butyne in ethanol.

Analogt med eksempel 38 erholdes de i eksemplene 1 til 2*f. såvel som 26 til 37 beskrevne forbindelser med formel I ved omsetning, av den tilsvarende forbindelse med.formel II med den tilsvarende forbindelse med formel III under anvendelse av fremgangsmåten a. Analogous to example 38, they are obtained in examples 1 to 2*f. as well as 26 to 37 described compounds of formula I by reaction, of the corresponding compound of formula II with the corresponding compound of formula III using method a.
