Description

141908141908

Den foreliggende opfindelse angår en analogifremgangsmåde til fremstilling af den hidtil ukendte forbindelse, l,8-dibrom-6- (o-chlorphenyl)-4H-s—triazolb-r[3,4- c]-thieno-[2,3-e]-l,4-diazepin med den i patentkravet an-5 givne formel I, eller dens fysiologisk acceptable syreadditionssalte .The present invention relates to an analogous process for the preparation of the novel compound, 1,8-dibromo-6- (o-chlorophenyl) -4H-s-triazolb-r [3,4-c] -thieno- [2,3- e] -1,4-diazepine of the formula I as claimed, or its physiologically acceptable acid addition salts.

Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at man bromerer en forbindelse med den i patentkravet angivne formel II, og at man eventuelt overfører forlo bindeisen med formlen I i et fysiologisk acceptabelt syreadditionssalt deraf.The process according to the invention is characterized by bromiding a compound of the formula II as claimed and optionally transferring the precursor of the formula I into a physiologically acceptable acid addition salt thereof.

Brameringen kan udføres i et opløsningsmiddel, såsom 'carbantetrachlorid, chloroform, methylenchlorid, dioxan, tetrahydrofuran, dimethylformaafd eller et egnet 15 carbonhydrid, eventuelt under tilsætning af en tertiær organisk base, såsom pyridin, eller også ved hjælp af et halogensuccinimid. Der anvendes afhængigt af det anvendte udgangsmateriale og den anvendte fremgangsmåde en reaktionstemperatur mellem stuetemperatur og tilbagesvalings-2o temperaturen af reaktionsblandingen.The bromination may be carried out in a solvent such as carbon tetrachloride, chloroform, methylene chloride, dioxane, tetrahydrofuran, dimethylformafide or a suitable hydrocarbon, optionally with the addition of a tertiary organic base such as pyridine, or also by a halogen succinimide. Depending on the starting material used and the method used, a reaction temperature between room temperature and the reflux temperature of the reaction mixture is used.

Forbindelsen med formlen I kan om ønsket på sædvanlig måde overføres i dens fysiologisk acceptable syreadditionssalte. Til saltdannelse egnede syrer er f. eks. hydrogenhalogenidsyrer, svovlsyre, phosphorsyre, 25 salpetersyre, cychlohexylsulfaminsyre, citronsyre, vinsyre, ascorbinsyre, maleinsyre, myresyre, salicylsyre eller methan- eller toluensulfonsyre og lignende.The compound of formula I may, if desired, be transferred in its usual manner into its physiologically acceptable acid addition salts. Suitable salts are, for example, hydrogen halide acids, sulfuric acid, phosphoric acid, nitric acid, cychlohexylsulfamic acid, citric acid, tartaric acid, ascorbic acid, maleic acid, formic acid, salicylic acid or methane or toluene sulfonic acid and the like.

Fremstilling af udgangsforbindelsen med formlen II kan ske ved omsætning af 7-brom-5-(o-chlorphenyl)-3H-3o [2,3-e]-thieno-l,4-diazepin-2-thion med myresyrehydrazid eller ved omsætning af 7-brom-5-(o-chlorphenyl)-2-hydra-zino-3H-[2,3-e]-thieno-l,4-diazepin med myresyre.The starting compound of formula II may be prepared by reacting 7-bromo-5- (o-chlorophenyl) -3H-3 [2,3-e] -thieno-1,4-diazepine-2-thione with formic acid hydrazide of 7-bromo-5- (o-chlorophenyl) -2-hydrazino-3H- [2,3-e] -thieno-1,4-diazepine with formic acid.

Forbindelsen med formlen I og dens syreadditionssalte udviser værdifulde terapeutiske egenskaber. Den 35 har ved anvendelse ved forskellige farmaceutiske afprøvningsmetoder vist anxiolytisk, spændingsopløsende og muskelrelaxerende aktivitet og har først og fremmest 2 141908 en kraftig antikonvulsiv virkning. Dens yderst ringe giftighed er også bemærkelsesværdig. Den er kendte thie-no-l,4-diazepiner uden yderligere triazolring, således som de f.eks. kendes fra DE-offentliggørelsesskrift nr.The compound of formula I and its acid addition salts exhibit valuable therapeutic properties. It 35, when used in various pharmaceutical testing methods, has shown anxiolytic, stress-relieving and muscle relaxant activity and, first and foremost, has a strong anticonvulsant effect. Its extremely low toxicity is also remarkable. It is known thie-no-1,4-diazepines without additional triazole ring, such as those e.g. is known from DE publication no.

5 2 155 403 og nr. 2 221 623, overlegen, især med hensyn til den ved den såkaldte pentetrazolprøve påviselige antikonvulsive aktivitet, medens den i virkemåde ganske vist ligner de fra DE-offentliggørelsesskrift nr.No. 5,215,403 and No. 2,221,623, particularly with respect to the anti-convulsive activity detectable by the so-called pentetrazole test, while in effect similar to those of DE Publication No.

2.229.845 og fra beskrivelsen til dansk patentansøgning 10 nr. 668/74 kendte 6-arylthieno[2,3-e]-4H-s-triazolo-[3,4-c]-l,4-diazepiner, men med hensyn til aktivitet overgår disse. Dette vil fremgå af følgende farmakologiske forsøg, hvor forbindelsen fremstillet ifølge den foreliggende opfindelse sammenlignedes med kemisk nærbe-15 slægtede forbindelser, kendt fra DE-offentliggørelses-skrift nr. 2.229.845 og fra beskrivelsen til dansk patentansøgning nr. 668/74.2,229,845 and from the specification to Danish patent application 10 No. 668/74 known 6-arylthieno [2,3-e] -4H-s-triazolo- [3,4-c] 1,4-diazepines, but with respect to to activity these outperform. This will be apparent from the following pharmacological experiments in which the compound prepared according to the present invention was compared with chemically closely related compounds, known from DE Publication No. 2,229,845 and from the specification to Danish Patent Application No. 668/74.

Ved disse forsøg anvendtes albino-mus (NMRI) med legemsvægt på 20-25 g eller albino-rotter (FW49) med 20 legemsvægt på 140-200 g. Med undtagelse af "Passive Avoi-dance-Test" anvendtes for hver dosis 10 dyr. "Passive Avoidance-Test" gennemførtes med 4 dyr for hvef dosis.In these experiments, albino mice (NMRI) with body weight of 20-25 g or albino rats (FW49) with 20 body weight of 140-200 g were used. With the exception of the "Passive Avoi-Dance Test", 10 doses were used for each dose. . "Passive Avoidance Test" was conducted with 4 animals for wheeze dose.

Testforbindelserne suspenderedes i olivenolie og indførtes i alle tilfælde i maven ved hjælp af svælg-25 sonde.The test compounds were suspended in olive oil and in all cases introduced into the stomach by a pharyngeal probe.

Res.,2, 721 (1965)).The dose at which the lethal effect of 125 mg / kg pentylenetetrazole administered intraperitoneally one hour after administration of the test compound is abolished in 50% of the animals. (M.I.Gluckmann, Curr. Ther. Res., 2, 721 (1965)).

2. Konfliktsituation (hæmning af "Passive Avoidance"):2. Conflict situation (inhibition of "Passive Avoidance"):

Den dosis, ved hvilken dyrene, der befinder sig i en konfliktsituation, 10 gange trykker på en knap for at 35 få foderpille, selv om et samtidig indskudt signal angiver, at der samtidig med foderpillen sker en afstraffelse i form af et elektrisk stød. (J.Geller, Arch. Int.The dose at which the animals are in a conflict situation presses a button 10 times to receive a feed pill, although a simultaneously inserted signal indicates that a punishment in the form of an electric shock occurs simultaneously with the feed pill.
