Definitions

  • the invention relates to imidates of the general formula I. in which R 1 , R 2 and R 3 , which may be the same or different from one another, are hydrogen, methyl, methoxy or chlorine, R 4 is hydrogen or alkyl having 1-4 C atoms, R 5 is alkyl having 1-6 C -Atoms or benzyl, R 6 is alkyl with 1-4 carbon atoms or benzyl, and n can be 0 or 1.
  • the substituents R 1 , R 2 and R 3 are preferably in the 3, 4 and 5 positions of the benzene ring.
  • the compounds of the general formula I according to the invention are prepared by the methods customary for the preparation of imidates, as described, inter alia, in Houben-Weyl, "Methods of Organic Chemistry", volume 6/3, by using a compound of the general formula II wherein R 1 , R 2 , R 3 , R 4 and n have the meaning given above, with an orthocarboxylic acid ester of the general formula III in which R 5 and R 6 have the meaning given above.
  • the compounds of the general formula I can be prepared with or without a solvent, the latter being carried out with an excess of the orthocarboxylic acid ester used.
  • suitable solvents are dimethylformamide or dioxane.
  • the reaction temperatures are between 0 and 150 ° C, preferably between 50 and 100 ° C or at temperatures up to the boiling point of the solvent or orthocarboxylic acid ester used.
  • the reaction can optionally be carried out in the presence of catalytic amounts of an acid, such as hydrochloric acid.
  • the compounds of the general formula according to the invention are antimicrobially active in diseases caused by bacteria and protozoa and, combined with sulfonamides, potentiate their antimicrobial activity. They can therefore be used, for example, for bacterial diseases of the respiratory, digestive and urinary tract, as well as for throat, nose and ear infections and general systemic infectious diseases and malaria.
  • the compounds of the general formula can be combined with the sulfonamides mentioned by way of example in various mixing ratios, the ratio of compound of the general formula I to sulfonamide varying from 1:10 to 5: 1.
  • Preferred mixing ratios are 1: 1 to 1: 5.
  • 20 to 500 mg of an active ingredient of the general formula are suitable as doses.
  • the present invention accordingly also relates to chemotherapeutic agents which, in addition to conventional carriers and diluents, contain a compound of the general formula I, in particular in combination with a sulfonamide, as active ingredients, and the use of the compounds of the general formula 1 as sulfonamide potentiators.
  • chemotherapeutic agents or preparations are produced in a known manner with the usual carriers or diluents and the commonly used pharmaceutical-technical auxiliaries in accordance with the desired type of application.
  • the preferred preparations are in a dosage form which is suitable for oral administration.
  • Dosage forms of this type are, for example, tablets, film-coated tablets, dragees, capsules, pills, powders, solutions or suspensions.
  • the active ingredients are mixed with corn starch and granulated with aqueous gelatin solution.
  • the dry granulate is sieved and mixed with the aggregates. Tablets are pressed from this mixture in the usual way.
  • the active ingredients are granulated with aqueous gelatin solution and, after drying, are mixed with corn starch, talc and magnesium stearate. Tablets are pressed from this mixture in the usual way.
  • the active ingredients are mixed with corn starch and granulated with an aqueous gelatin solution.
  • the dry granulate is sieved and mixed with the aggregates. Tablets are pressed from this mixture in the usual way.
  • the finely ground active ingredients are suspended in the aqueous tylose mucus. Then all other ingredients are added in succession with stirring. Finally, make up to 100.0 g with water.
