Definitions

  • Thieno-triazolo-diazepines are known to be anxiolytic, muscle relaxant and anticonvulsant. These are compounds which are attached to the triazole ring, for example by alkyl (DT-OS 2405682), cycloalkyl (DBP 2435041), an oxygen-containing 5- or 6-membered ring (DT-AS 2445430) or a nitrogen or sulfur-containing 5- or 6-membered ring (DT-OS 2460776) are substituted.
  • 8-bromo-6- (o-chlorophenyl) -1- [N- (2-hydroxyethyl) piperazinyl] -4H-s-triazolo [3,4c] thieno [2,3e] 1,4-diazepine Salts form and, in this form, have a water solubility of 0.5% which is important for the diazepine substance class. This allows parenteral use of the compound, e.g. in the anesthetic preparation.
  • 8-bromo-6- (o-chlorophenyl) -1-methyl-4H-s-triazalo [3,4c] thieno [2,3e] 1,4-diazepine extends deep and REM sleep and impresses to a much greater extent the engine coordination.
  • reaction of compounds of general formula II with a piperazine of formula 111 is carried out either without a solvent or in higher-boiling solvents such as benzene, toluene, dioxane, tetrahydrofuran, chlorinated hydrocarbons such as carbon tetrachloride or methylene chloride, preferably at the boiling point of the solvent used.
  • the reaction time depends on the starting material used and can range from a few minutes to several hours.
  • dehydrogenation of compounds of the general formula IV is carried out using suitable dehydrogenation agents such as, for example, halogens or else compounds of the higher oxidation states of chromium or manganese, for example a chromate, a bichromate or a permanganate.
  • suitable dehydrogenation agents such as, for example, halogens or else compounds of the higher oxidation states of chromium or manganese, for example a chromate, a bichromate or a permanganate.
  • Chlorinated hydrocarbons such as chloroform or methylene chloride may be mentioned as suitable solvents for the reaction with a halogen.
  • the oxidation with the mentioned chromium or manganese compounds takes place in solvents such as acetone, tetrahydrofuran or dioxane.
  • the reaction temperature is generally between 0 ° C and the boiling point of the solvent used.
  • the 8-bromo-6- (o-chlorophenyl) -1- [N- (2-hydroxyethyl) piperazinyl] -4H-s-triazolo [3,4c] thieno no [2,3e] forms 1,4-diazepine stable water-soluble salts.
  • Suitable for salt formation are all acids which form physiologically acceptable acid addition salts such as hydrohalic acids, sulfuric acid, phosphoric acid, nitric acid, cyclohexylsulfamic acid, citric acid, tartaric acid, ascorbic acid, maleic acid, formic acid, salicylic acid, methane or toluenesulfonic acid.
  • the starting compounds of the general formula II are known from the literature.
  • Starting compounds of the general formula IV are obtained by reacting a compound of the formula in the Hal means a halogen atom, with a piperazine derivative of the formula 111 under the conditions given under a) and then replacing the ring oxygen atom with a nitrogen atom, as described, for example, in German application P 2531678.
  • the single dose of the substances according to the invention is 0.05 to 50, preferably 0.1 to 25 mg (oral) and 5 to 150 mg as a daily dose.
  • the compounds obtainable according to the invention can be used alone or in combination with other active substances according to the invention, optionally also in combination with other pharmcologically active substances such as spasmolytics or ⁇ -receptor blockers.
  • Suitable forms of use are, for example, tablets, capsules, suppositories, solutions, juices, emulsions or dispersible powders.
  • Corresponding tablets can be obtained, for example, by mixing the active ingredient (s) with known auxiliaries, for example inert diluents, such as calcium carbonate, calcium phosphate or lactose, disintegrants, such as corn starch or alginic acid, binders, such as starch or gelatin, lubricants, such as magnesium stearate or talc, and / or agents to achieve the depot effect, such as carboxypolymethylene, carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate.
  • auxiliaries for example inert diluents, such as calcium carbonate, calcium phosphate or lactose, disintegrants, such as corn starch or alginic acid, binders, such as starch or gelatin, lubricants, such as magnesium stearate or talc, and / or agents to achieve the depot effect, such as carboxypolymethylene, carboxymethyl cellulose, cellulose acetate phthalate
  • coated tablets can be produced by coating cores produced analogously to the tablets with agents conventionally used in coated tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar.
  • the core can also consist of several layers to achieve a deposit effect or to avoid incompatibilities.
  • the coated tablet shell can also consist of several layers in order to achieve a depot effect, it being possible to use the auxiliaries mentioned above for the tablets.
  • Juices of the active substances or combinations of active substances according to the invention can additionally contain a sweetener such as saccharin, cyclamate, glycerol or sugar as well as a taste-improving agent, e.g. Flavorings, such as vanillin or orange extract, contain. You can also use suspension aids. or thickeners, such as sodium carboxymethyl cellulose, wetting agents, for example condensation products of fatty alcohols with ethylene oxide, or protective substances, such as p-hydroxybenzoates.
