Description

Foreliggende oppfinnelse angår fremstilling av nye aminoalkanoyl-dibenzo[d,g][1,3,6]dioxazociner. The present invention relates to the production of new aminoalkanoyl-dibenzo[d,g][1,3,6]dioxazocines.

De nye forbindelser utviser verdifulle farmasøytiske egenskaper slik som lokalbedøvende aktivitet, beroligende-sedativ aktivitet og/eller antidepressiv aktivitet, er anti-parkinsonmidler og utviser enn videre antiarytmisk og antiangina-aktivitet. The new compounds exhibit valuable pharmaceutical properties such as local anesthetic activity, sedative-sedative activity and/or antidepressant activity, are anti-Parkinsonian agents and furthermore exhibit anti-arrhythmic and anti-anginal activity.

12-aminoalkyl-12H-dibenzo[d,g][l,3,6]dioxazociner med lokalbedøvende og antiparkinson-aktivitet er beskrevet i U.S. patentskrift 4 208 410. 12-Aminoalkyl-12H-dibenzo[d,g][1,3,6]dioxazocines with local anesthetic and antiparkinsonian activity are described in U.S. Pat. patent document 4 208 410.

Fra US patentskrift 4 299 350 og 4 208 410 er det i eksempel 6 beskrevet forbindelsen 2-klor-12-(3-dimethylamino-2-methylpropyl)-12H-dibenzo[d,g][1,3,6]dioxazocin. Denne forbindelse er lett tilgjengelig under dens internasjonale navn traboxopin. From US patent documents 4,299,350 and 4,208,410, the compound 2-chloro-12-(3-dimethylamino-2-methylpropyl)-12H-dibenzo[d,g][1,3,6]dioxazocine is described in example 6. This compound is readily available under its international name traboxopin.

Sammenlikner man den aktivitet som er angitt i tabell III i foreliggende beskrivelse er ED50-verdien for traboxopin 25,0 mg/kg og den terapeutiske indeks for forbindelsen er 10,8. Sammenlikner man aktiviteten av forbindelsene ifølge eksempel 1 og 4 er aktiviteten av traboxopin meget lavere. Med hensyn til antagonisme av tetrabenazin-dose (se tabell IV) utviser traboxopin ikke noen inhiberende aktivitet ved denne test idet toksisk interaksjon finner sted. Comparing the activity indicated in Table III of the present specification, the ED50 value for traboxopin is 25.0 mg/kg and the therapeutic index for the compound is 10.8. If you compare the activity of the compounds according to examples 1 and 4, the activity of traboxopin is much lower. With respect to antagonism of tetrabenazine dose (see Table IV), traboxopin does not exhibit any inhibitory activity in this test as toxic interaction occurs.

Denne test er karakteristisk for den antidepressive aktivitet. Med hensyn til den nikotin-letalitetsinhiberende aktivitet (se tabell V) er ED50-verdien for traboxopin 11,2 mg/kg mens dens terapeutiske indeks er 25. Sammenlikner man verdiene for forbindelsen ifølge eksempel 3 og 5 fremgår det klart at trapoxopin har lavere aktivitet. This test is characteristic of the antidepressant activity. With respect to the nicotine lethality inhibitory activity (see Table V), the ED50 value for traboxopin is 11.2 mg/kg while its therapeutic index is 25. Comparing the values for the compound according to examples 3 and 5, it is clear that traboxopin has lower activity .

Med hensyn til den tremor-inhiberende aktivitet (se tabell VI), er ED50-verdien for en traboxopin 11 mg/kg, mens dens terapeutiske indeks er 25. Sammenlikner man verdiene for forbindelsene ifølge eksempel 1, 3 og 13 fremgår det klart at traboxopin er mindre aktiv. With regard to the tremor-inhibiting activity (see Table VI), the ED50 value of a traboxopin is 11 mg/kg, while its therapeutic index is 25. Comparing the values of the compounds of Examples 1, 3 and 13, it is clear that traboxopin is less active.

Med hensyn til den antiarytmiske aktivitet utviser traboxopin ingen slik effekt overhodet, mens alle forbindelsene fremstilt ifølge oppfinnelsen oppført i tabell VII har en glimrende aktivitet. With regard to the antiarrhythmic activity, traboxopin exhibits no such effect at all, while all the compounds produced according to the invention listed in Table VII have an excellent activity.

Med hensyn til antiangina-aktiviteten har traboxopin ingen bestembar aktivitet. Derimot er forbindelsen ifølge eksempel 15 og 21 fordelaktige antiangina-midler. With regard to antianginal activity, traboxopin has no detectable activity. In contrast, the compound according to examples 15 and 21 are advantageous antianginal agents.

Som en konklusjon kan det således fastslås at erstat-ning av aminoalkyl-gruppen av de kjente forbindelser med en aminoalkanoyl-gruppe resulterer i en lavere lokal anestetisk aktivitet men samtidig oppstår nye aktiviteter, nemlig antidepressiv, antiarytmisk og antiangina-aktivitet. Det spektrum av aktiviteter kunne således ikke forutses ut fra kjennskap til de kjente publikasjoner. As a conclusion, it can thus be established that replacing the aminoalkyl group of the known compounds with an aminoalkanoyl group results in a lower local anesthetic activity but at the same time new activities occur, namely antidepressant, antiarrhythmic and antianginal activity. The spectrum of activities could thus not be predicted based on familiarity with the known publications.

Det ble funnet at den farmasøytiske aktivitet av de kjente forbindelser kan gunstig modifiseres ved å substitu-ere ringnitrogenet med en aminoalkanoylgruppe i stedet for en aminoalkylgruppe. It was found that the pharmaceutical activity of the known compounds can be favorably modified by substituting the ring nitrogen with an aminoalkanoyl group instead of an aminoalkyl group.

Oppfinnelsen angår således en analogifremgangsmåte for fremstilling av nye, terapeutisk aktive aminoalkanoyl-dibenzo[d,g][1,3,6]dioxazociner av formel The invention thus relates to an analogous process for the production of new, therapeutically active aminoalkanoyl-dibenzo[d,g][1,3,6]dioxazocines of the formula

I fremgangsmåte a) ifølge oppfinnelsen acyleres forbindelsene av formel (II) i et apolart eller dipolart aprotisk løsningsmiddel, fortrinnsvis benzen, toluen, xylen eller dimethylformamid, i nærvær eller fravær av et syrebindende middel. Acetyleringsmidlet av formel (III) anvendes i en ekvivalent mengde eller i overskudd i forhold til mengden av dibenzo[d,g][1,3,6]dioxazocin av formel (II). In method a) according to the invention, the compounds of formula (II) are acylated in an apolar or dipolar aprotic solvent, preferably benzene, toluene, xylene or dimethylformamide, in the presence or absence of an acid-binding agent. The acetylating agent of formula (III) is used in an equivalent amount or in excess in relation to the amount of dibenzo[d,g][1,3,6]dioxazocine of formula (II).

Det foretrekkes å acylere forbindelsen av formel (II) i toluen, generelt ved en temperatur på 60-110°C med forbindelsen av formel (III) som anvendes i et overskudd på 200-300 %.

Fortrinnsvis anvendes benzen, toluen, xylen, isopropanol eller dimethylformamid som løsningsmid-del. Aminet av formel (VIII) kan anvendes i en ekvimolar mengde eller i overskudd. Overskudd av aminet av formel (VIII) kan binde hydrogenhalogenidet som dannes ved reaksjonen. Imidlertid kan også andre vanlige syrebindende midler anvendes for dette formål. Omega-halo-alkanoyl-dibenzo[d,g][l,3,6]dioxazocine of formula (IV) formed by the acylation reaction is reacted in a polar, apolar or dipolar solvent with the amine of formula (VIII). Benzene, toluene, xylene, isopropanol or dimethylformamide are preferably used as solvent. The amine of formula (VIII) can be used in an equimolar amount or in excess. Excess of the amine of formula (VIII) can bind the hydrogen halide which is formed by the reaction. However, other common acid binding agents can also be used for this purpose.

Det syrebindende middel anvendt både ved acyleringen og amineringen kan være en egnet uorganisk base, f.eks. natriumcarbonat, kaliumcarbonat etc, eller en egnet organisk base slik som et tertiært amin, f.eks. triethyl-amin, N,N-diisopropyl-N-ethylamin, pyridin. The acid binding agent used in both the acylation and the amination can be a suitable inorganic base, e.g. sodium carbonate, potassium carbonate etc, or a suitable organic base such as a tertiary amine, e.g. triethylamine, N,N-diisopropyl-N-ethylamine, pyridine.

Det foretrekkes å omsette forbindelsen av formel (IV) i benzen med et overskudd av aminet av formel (VIII). It is preferred to react the compound of formula (IV) in benzene with an excess of the amine of formula (VIII).

Fremgangsmåte a) ifølge oppfinnelsen kan utføres ved å starte fra et metallsalt av forbindelsen av formel (II). I dette tilfelle omsettes forbindelsen av formel (II) med eksempelvis natriumhydrid eller natriumamid i et polart aprotisk løsningsmiddel, hensiktsmessig dimethylformamid, under dannelse av det tilsvarende natriumsalt derav, som acyleres generelt ved 0-40°C. Ved denne acylering er selv-sagt intet syrebindende middel nødvendig. Method a) according to the invention can be carried out by starting from a metal salt of the compound of formula (II). In this case, the compound of formula (II) is reacted with, for example, sodium hydride or sodium amide in a polar aprotic solvent, preferably dimethylformamide, forming the corresponding sodium salt thereof, which is generally acylated at 0-40°C. With this acylation, of course no acid-binding agent is necessary.

I fremgangsmåte b) ifølge oppfinnelsen acyleres forbindelsen av formel (II) med forbindelsen av formel (V) på en lignende måte, generelt ved 0-140°C. In method b) according to the invention, the compound of formula (II) is acylated with the compound of formula (V) in a similar way, generally at 0-140°C.

Det foretrekkes å fremstille alkalimetallsaltet av forbindelsen av formel (II) først, og deretter omsette dette med et overskudd av forbindelsen av formel (V) ved en temperatur på fra 0-50°C. It is preferred to prepare the alkali metal salt of the compound of formula (II) first, and then react this with an excess of the compound of formula (V) at a temperature of from 0-50°C.

I fremgangsmåte c) ifølge oppfinnelsen utføres reaksjonen mellom forbindelsene av formel (II) og (VI) i et apolart organisk løsningsmiddel, slik som benzen, toluen eller xylen, generelt ved 50-140°C. Den erholdte forbindelse av formel (VII) omsettes med aminet av formel (VIII) ved atmosfæretrykk eller under høyere trykk. For reaksjonen er løsningsmidlet et apolart organisk løsningsmiddel eller et overskudd av aminet av formel (VIII). In method c) according to the invention, the reaction between the compounds of formula (II) and (VI) is carried out in an apolar organic solvent, such as benzene, toluene or xylene, generally at 50-140°C. The obtained compound of formula (VII) is reacted with the amine of formula (VIII) at atmospheric pressure or under higher pressure. For the reaction, the solvent is an apolar organic solvent or an excess of the amine of formula (VIII).

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]-[l,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]-[l,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

(VI). (WE).

Forbindelsene av formel (I) utviser verdifulle farmakologiske aktiviteter som vist ved de etterfølgende screen-ingstester. The compounds of formula (I) exhibit valuable pharmacological activities as shown by the subsequent screening tests.

Akutt toksisitet i hvite mus Acute 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. LD5Ø-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 LD5Ø 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 konsentrasj oner. 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.

Søvn fremkalt med hexobarbital hos mus Sleep induced with hexobarbital in mice

Grupper bestående av 6 mus ble hver behandlet peroralt med testforbindelsen. Etter en time ble hexobarbital[5-(1-cyklohexenyl)-l,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 ED50-verdien beregnet. Fra verdiene for LD50 og ED50 ble den terapeutiske indeks bestemt for hver testforbindelse. I testen ble meprobamat[2-methyl-2-propylpropandiol-l,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 ED50 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 mus Antagonism 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, 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 ED5Q-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. 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 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 ED5Q 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.

Den terapeutiske indeks for forbindelsene ifølge oppfinnelsen er generelt høyere enn den av amitryptilinet anvendt for sammenligning. The therapeutic index of the compounds according to the invention is generally higher than that of amitriptyline used for comparison.

Inhibering av nikotinletalitet på mus Inhibition 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 trihexyfenidyltalfa-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.-Forsch., 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.
