I forbindelser av formel (I), omfattende en eller flere kirale carbonatomer, kan enantiomerene separeres ved oppløsning av den racemiske forbindelse. For å bevirke dette, omsettes den racemiske forbindelse, omfattende et basisk nitrogen, med en optisk aktiv carboxylsyre under dannelse av par av diastereomere salter som separeres, og enantiomerene frigis. Som optisk aktiv, organisk syre kan enhver carboxylsyre anvendt for oppløsninger anvendes, slik som optisk aktiv vinsyre, dibenzoylvinsyre, melkesyre, atro-melkesyre, mandelsyre etc, og optisk aktive sulfonsyrer slik som 10-kamfersulfonsyre. In compounds of formula (I), comprising one or more chiral carbon atoms, the enantiomers can be separated by resolution of the racemic compound. To effect this, the racemic compound, comprising a basic nitrogen, is reacted with an optically active carboxylic acid to form pairs of diastereomeric salts which separate, and the enantiomers are released. As an optically active organic acid, any carboxylic acid used for solutions can be used, such as optically active tartaric acid, dibenzoyltartaric acid, lactic acid, atrolactic acid, mandelic acid, etc., and optically active sulphonic acids such as 10-camphor sulphonic acid.

Enantiomerene av de nye aminoalkanoyl-dibenzo[d,g]-[1,3,6]dioxazociner, omfattende et kiralt carbonatom, kan også fremstilles ved acylering av forbindelsen av formel (II) med et optisk aktivt middel av formel (III), (V) eller The enantiomers of the new aminoalkanoyl-dibenzo[d,g]-[1,3,6]dioxazocines, comprising a chiral carbon atom, can also be prepared by acylation of the compound of formula (II) with an optically active agent of formula (III), (V) or

Akutt toksisitet i hvite musAcute toxicity in white mice

Akutt toksisitet av forbindelsene ble testet på hvite mus av begge kjønn fra stamme CFLP i grupper bestående av 10 dyr som veide 18-22 g. Testforbindelsene ble administrert oralt i et volum på 20 ml/kg. Etter administreringen ble musene observert i 7 dager mens de ble holdt i plastbur over et strø fremstilt av spon ved romtemperatur. Dyrene kunne konsumere kranvann og standard musefor ad lib. LD5Q-verdiene ble bestemt iht. Litchfield og Wilcoxon [J. Pharma-col. Exp. Ther., 96, 99 (1949)]. De erholdte resultater er vist i tabell I. Acute toxicity of the compounds was tested on white mice of both sexes from strain CFLP in groups consisting of 10 animals weighing 18-22 g. The test compounds were administered orally in a volume of 20 ml/kg. After the administration, the mice were observed for 7 days while kept in plastic cages over a litter made of shavings at room temperature. The animals could consume tap water and standard mouse chow ad lib. The LD5Q values were determined according to Litchfield and Wilcoxon [J. Pharma-col. Exp. Ther., 96, 99 (1949)]. The results obtained are shown in table I.

Lokalbedøvende aktivitet Local anesthetic activity

Testene ble utført iht. Truant d'Amato [Acta Chir. Scand., 116, 351 (1958)]. 0,2 ml av en 0,25 eller 0,50 % løsning av testforbindelsen ble injisert rundt isjiasnerven inn i senteret av låret. Fravær av motorisk kontroll av leggmusklene ble betraktet som et kriterium på bedøvelse. Testdyrene var mus. Varigheten av effekten ble nedtegnet, og fra dose versus virkningskurven ble den konsentrasjon ved hvilken aktiviteten utgjorde 50 % (EC50), bestemt. I testen ble lidocain[2-diethylamino-2',6'-acetoxy-xylidid] anvendt for sammenligningens skyld. De erholdte resultater er angitt i tabell II. The tests were carried out in accordance with Truant d'Amato [Acta Chir. Scand., 116, 351 (1958)]. 0.2 ml of a 0.25 or 0.50% solution of the test compound was injected around the sciatic nerve into the center of the thigh. Absence of motor control of the calf muscles was considered a criterion for anesthesia. The test animals were mice. The duration of the effect was recorded, and from the dose versus effect curve the concentration at which the activity was 50% (EC50) was determined. In the test, lidocaine [2-diethylamino-2',6'-acetoxy-xylidide] was used for the sake of comparison. The results obtained are shown in table II.

Fra tabell II fremgår det at de fleste testede forbindelser er effektive i en lavere konsentrasjon enn lidocain. Varigheten av effekten av alle forbindelsene ifølge oppfinnelsen er meget lenger enn effekten av lidocain ved begge konsentrasjoner. Table II shows that most tested compounds are effective in a lower concentration than lidocaine. The duration of the effect of all the compounds according to the invention is much longer than the effect of lidocaine at both concentrations.

Etter en time ble hexobarbital[5-(1-cyklohexenyl)-1,5-dimethylbarbitursyre ble injisert intra-venøst i en dose på 40 mg/kg. Kontrollgruppen ble bare behandlet med hexobarbital for å bevirke søvn. Varigheten av søvnen ble nedtegnet. Hvis varigheten av søvnen av et dyr overskred den av middelverdien for kontrollgruppen med en faktor på 2,5, ble dette betraktet som en positiv reaksjon. Fra dataene som henviste til dyr som utviste en positiv reaksjon, ble ED5g-verdien beregnet. Fra verdiene for LD50og ED50ble den terapeutiske indeks bestemt for hver testforbindelse. I testen ble meprobamat[2-methyl-2-propylpropandiol-1,3-dicarbamat] og klordiazepoxid[7-klor-2- methylamino-5-fenyl-3H-l,4-benzodiazepin-4-oxid] anvendt for sammenligningens skyld. De erholdte resultater er oppført i tabell III. Groups consisting of 6 mice were each treated orally with the test compound. After one hour, hexobarbital [5-(1-cyclohexenyl)-1,5-dimethylbarbituric acid was injected intravenously at a dose of 40 mg/kg. The control group was only treated with hexobarbital to induce sleep. The duration of sleep was recorded. If the duration of sleep of an animal exceeded that of the mean value of the control group by a factor of 2.5, this was considered a positive reaction. From the data referring to animals showing a positive reaction, the ED5g value was calculated. From the LD50 and ED50 values, the therapeutic index was determined for each test compound. In the test, meprobamate [2-methyl-2-propylpropanediol-1,3-dicarbamate] and chlordiazepoxide [7-chloro-2-methylamino-5-phenyl-3H-1,4-benzodiazepine-4-oxide] were used for the sake of comparison . The results obtained are listed in table III.

Fra dataene angitt i tabell III fremgår det at den terapeutiske indeks for den mest effektive nye forbindelse (dvs. forbindelsen fremstilt i eksempel 4) er i en størrel-sesorden høyere enn den av klordiazepoxid. Samtidig er forbindelsene ifølge oppfinnelsen mer effektive enn meprobamat anvendt som referanse. From the data given in Table III it appears that the therapeutic index of the most effective new compound (ie the compound prepared in Example 4) is an order of magnitude higher than that of chlordiazepoxide. At the same time, the compounds according to the invention are more effective than meprobamate used as a reference.

Antagonisme av tetrabenazinptosis på musAntagonism of tetrabenazine ptosis in mice

Testene ble utført etter metoden ifølge Hoffmeister et al., som ble tilpasset til mus [Arzneim.-Forschung, 19, 846-858 (1969)]. Grupper bestående av 10 mus hver ble behandlet peroralt med forskjellige doser av testforbindelsene. Kontrollgruppen ble behandlet bare med den tilsvarende bærer. Etter 30 min. ble tetrabenazin[3-isobutyl-9,10-dimethoxy-1,2,3,4,6,7-hexahydrobenzo[a]kinolizin-2-on] administrert intraperitonealt i en dose på 50 mg/kg. Antall dyr med lukket øyelokkspalte ble bestemt i hver gruppe etter 30, 60, The tests were carried out according to the method according to Hoffmeister et al., which was adapted to mice [Arzneim.-Forschung, 19, 846-858 (1969)]. Groups consisting of 10 mice each were treated orally with different doses of the test compounds. The control group was treated only with the corresponding vehicle. After 30 min. tetrabenazine[3-isobutyl-9,10-dimethoxy-1,2,3,4,6,7-hexahydrobenzo[a]quinolizin-2-one] was administered intraperitoneally at a dose of 50 mg/kg. The number of animals with a closed eyelid cleft was determined in each group after 30, 60,

90 og 120 min. Deretter ble middelverdien av ptosis beregnet i hver gruppe, og avviket fra denne av kontrollgruppen (dvs. inhiberingen) ble uttrykt-i prosent. Fra de erholdte data ble ED50-verdien og den terapeutiske indeks bestemt for hver ny testforbindelse, så vel som for amitryptilin[5-(3-di-methyl-aminopropylidin)-10,ll-dihydro-5H-dibenzo[a,d]-cyklo-hepten-hydroklorid] anvendt for sammenligningens skyld. De erholdte resultater er vist i tabell IV. 90 and 120 min. Then the mean value of ptosis was calculated in each group, and the deviation from this of the control group (ie the inhibition) was expressed as a percentage. From the data obtained, the ED50 value and the therapeutic index were determined for each new test compound, as well as for amitriptyline [5-(3-di-methyl-aminopropylidine)-10,11-dihydro-5H-dibenzo[a,d] -cycloheptene hydrochloride] used for the sake of comparison. The results obtained are shown in table IV.

Inhibering av nikotinletalitet på musInhibition of nicotine lethality in mice

Testene ble utført på hvite mus under anvendelse av metoden ifølge Stone [Arch. Int. Pharmacodyn., 177, 419 The tests were performed on white mice using the method according to Stone [Arch. Int. Pharmacodyn., 177, 419

(1958)]. Dyrene ble behandlet med testforbindelsene oralt, hvoretter nikotin ble injisert intravenøst i en dose på 1,4 mg/kg etter en time. Spasmene så vel som letaliteten observert innen en time, ble nedtegnet, ED5Q-verdien og den terapeutiske indeks ble regnet for hver ny testforbindelse og for trihexyfenidyl[alfa-cyklohexyl-alfa-fenyl-piperidin-propanol-hydroklorid] anvendt for sammenligning. Test-resultatene er angitt i tabell V. (1958)]. The animals were treated with the test compounds orally, after which nicotine was injected intravenously at a dose of 1.4 mg/kg after one hour. The spasms as well as the lethality observed within one hour were recorded, the ED5Q value and the therapeutic index were calculated for each new test compound and for trihexyphenidyl [alpha-cyclohexyl-alpha-phenyl-piperidine-propanol hydrochloride] used for comparison. The test results are given in Table V.

Inhibering av tremor fremkalt av tremorin på mus Inhibition of tremors induced by tremorin in mice

Testene ble utført iht. Everett [Science, 124, 79 The tests were carried out in accordance with Everett [Science, 124, 79

(1956)]. Skjelving ble fremkalt med tremorin[1,1'-(2-butyn-ylen)-dipyrrolidin] administrert intraperitonealt i en dose på 20 mg/kg. Testforbindelsene ble gitt peroralt til dyrene i en time før administreringen av tremorin, og den utviklede skjelving ble bestemt 45 min. etter administrering av tremorin. Resultatene er angitt i tabell VI. (1956)]. Tremor was induced with tremorin[1,1'-(2-butyn-ylene)-dipyrrolidine] administered intraperitoneally at a dose of 20 mg/kg. The test compounds were given orally to the animals one hour before the administration of tremorin, and the developed tremor was determined 45 min. after administration of tremorin. The results are shown in Table VI.

Da inhibering av nikotinletalitet og av skjelving er karakteristisk for antiparkinson-aktivitet av en forbindelse, kan det fra tabellene V og VI konkluderes med at antiparkinson-aktiviteten av forbindelsene overgår den av den kjente forbindelse anvendt for sammenligning, ved å betrakte enten den absolutte dose eller den terapeutiske indeks. Since inhibition of nicotine lethality and of tremor is characteristic of antiparkinsonian activity of a compound, it can be concluded from Tables V and VI that the antiparkinsonian activity of the compounds exceeds that of the known compound used for comparison, considering either the absolute dose or the therapeutic index.

En forsøkskoronarinsuffisiens ble utviklet ved administrering av glanduitrin - et ekstrakt fra bakre hypofysila - i en intravenøs dose på 4 IU/kg. Høyden av T-bølgen i EKG ble målt før og etter administreringen av glanduitrin både i kontroll- og de behandlede grupper, og inhiberingen tilveiebrakt av testforbindelsene ble beregnet. I testen ble prenylamin[3,3-difenylpropyl-l-methylfenethyl-aminlaktat] anvendt for sammenligning. The antianginal activity of the compounds was determined on anesthetized (for this purpose chloralose urethane was used) male rats weighing 180-200 g according to Nischultz [Arzneim.-Forsen., 5, 680 (1955)]. An experimental coronary insufficiency was developed by the administration of glanduitrin - an extract from the posterior pituitary - in an intravenous dose of 4 IU/kg. The height of the T wave in the ECG was measured before and after the administration of glanduitrin in both the control and the treated groups, and the inhibition provided by the test compounds was calculated. In the test, prenylamine [3,3-diphenylpropyl-1-methylphenethylamine lactate] was used for comparison.
