Description
Denne oppfinnelse angår en fremgangsmåte for fremstilling av terapeutisk aktive aminoetanolderivater med den generelle formel: This invention relates to a process for the production of therapeutically active aminoethanol derivatives with the general formula:
hvor R er hydrogen eller hydroksyl, og OH-gruppen er i m- eller p-stilling til etanolamindelen, idet R er hydrogen når OH-gruppen er i p-stilling, where R is hydrogen or hydroxyl, and the OH group is in the m- or p-position to the ethanolamine part, with R being hydrogen when the OH group is in the p-position,
i form av racematene, eventuelt de diastereomere antipodepar, og syreaddisjonssaltene derav. in the form of the racemates, possibly the diastereomeric antipode pairs, and the acid addition salts thereof.
I henhold til oppfinnelsen fremstilles de nye forbindelser ved en av de følgende fremgangsmåter: According to the invention, the new compounds are produced by one of the following methods:
1. Fra en forbindelse med den generelle formel: 1. From a compound with the general formula:
hvor R^ og R2 betyr hydrogenolytisk avspaltbare rester eller hvor også en av restene R^ og R2 kan bety et hydrogenatom, avspaltes den (de) gruppe(r) som skal fjernes.Avspaltningen foretas ved where R^ and R2 mean hydrogenolytically cleavable residues or where one of the residues R^ and R2 can also mean a hydrogen atom, the group(s) to be removed are cleaved off. Cleavage is carried out by
hydrogenering i nærvær av en katalysator, særlig av nikkel, platina eller palladium. hydrogenation in the presence of a catalyst, in particular of nickel, platinum or palladium.
2. En forbindelse med den generelle formel: 2. A compound with the general formula:
reduseres. is reduced.
Reduksjonen foretas hensiktsmessig ved katalytisk hydrogenering over nikkel-, platina- eller palladiumkatalysatorer eller ved reduksjon med komplekse hydrider, særlig natriumboranat. The reduction is suitably carried out by catalytic hydrogenation over nickel, platinum or palladium catalysts or by reduction with complex hydrides, particularly sodium borate.
3. En forbindelse-med den generelle formel:. 3. A compound-with the general formula:.
ii ii
hvor B betyr =0 eller where B means =0 or
reduseres. is reduced.
Hvis B betyr et oksygenatom, reduseres begge karbonylgrupper samtidig, Som reduksjonsmiddel kan anvendes hydrogen og vanlige katalysatorer, f. eks. av nikkel, platina eller palladium, eller komplekse hydrider, særlig natriumboranat. If B means an oxygen atom, both carbonyl groups are reduced simultaneously. Hydrogen and common catalysts, e.g. of nickel, platinum or palladium, or complex hydrides, especially sodium borate.
Om ønsket kan de erholdte produkter ved vanlige metoder separeres i de diastereomere antipodepar og / eller overføres til ønskede syreaddisjonssalter. If desired, the products obtained can be separated by usual methods into the diastereomeric antipodal pairs and/or transferred to the desired acid addition salts.
Utgangsstoffene fremstilles ved metoder som er kjente for fremstilling av slike forbindelser. The starting materials are prepared by methods which are known for the preparation of such compounds.
De nye forbindelser fremstilt i henhold til oppfinnelsen er terapeutisk aktive. De er særlig egnet som aktive bestand- The new compounds produced according to the invention are therapeutically active. They are particularly suitable as active ingredients
deler i hjerte- og kretsløpmidler. De anvendes i form av vanlige galeniske preparater sammen med vanlige hjelpe- og bæremidler f. eks. i form av tabletter, drageer, kapsler, aerosoler, dråpe-og injeksjonsoppløsninger. Enkeltdosen er ca 0,1 til ca 20 mg. parts in cardiac and circulatory agents. They are used in the form of ordinary galenic preparations together with ordinary aids and carriers, e.g. in the form of tablets, dragees, capsules, aerosols, drop and injection solutions. The single dose is about 0.1 to about 20 mg.
Lignende forbindelser er kjent fra US-patent 3 341 593 som Similar compounds are known from US patent 3,341,593 as
blant annet angår handelsproduktet "Berotec" (R i formel I i patentet betyr H). Sammenlignet med denne kjente forbindelse utmerker forbindelsen fremstilt ifølge eksempel 1 seg ved among other things concerns the commercial product "Berotec" (R in formula I in the patent means H). Compared to this known compound, the compound prepared according to example 1 excels by
a) bedre peroral virkning, og a) better oral effect, and
b) lengre virkningsvarighet. b) longer duration of action.
Den bedre perorale virkning ble demonstrert på hunder ved be-stemmelse av takykardi efter oral og intramuskulær administrering. Ved sammenligning av de doser som medfører samme hjertevirkning, får man resorpsjonskvotienten oral/intramuskulær. Den utgjør for forbindelsen fremstilt ifølge oppfinnelsen 4,1, og for den kjente forbindelse 20. Således er den orale virkning av den nye forbindelse nesten fem ganger bedre enn virkningen for den kjente forbindelse. Det er lett å innse at den bedre orale virkning representerer en vesentlig fordel for terapeutiske formål. For halveringstiden av virkningsvarigheten (hjertevirkning) får man for forbindelsen fremstilt ifølge oppfinnelsen: 152 min. forbindelsen ifølge US-patentet: 33 min. The better oral effect was demonstrated in dogs by determining tachycardia after oral and intramuscular administration. When comparing the doses that lead to the same cardiac effect, the resorption quotient oral/intramuscular is obtained. It amounts to 4.1 for the compound produced according to the invention, and 20 for the known compound. Thus, the oral effect of the new compound is almost five times better than the effect of the known compound. It is easy to realize that the better oral effect represents a significant advantage for therapeutic purposes. For the half-life of the duration of action (cardiac action), one obtains for the compound produced according to the invention: 152 min. the compound according to the US patent: 33 min.

Den anvendte metodikk var som følger: The methodology used was as follows:
Til narkotiserte hunder (kloralose-uretan-narkose) ble det arterielle blodtrykk målt med en Statham-trykkomformer, og koro-nargjennomblødningen med en elektromagnetisk strømningsmåler i den nedgående gren.av den venstre koronararterie. Forbindelsen ble administrert arterielt (i en koronararterie) eller intra-venøst. In anesthetized dogs (chloralose urethane anesthesia) the arterial blood pressure was measured with a Statham pressure transducer, and the coronary perfusion with an electromagnetic flow meter in the descending branch of the left coronary artery. The compound was administered arterially (into a coronary artery) or intravenously.
