Definitions

  • the invention relates to 2,4-diamino-5-benzylpyrimidines of the general formula I.
  • R 1 , R 2 and R 3 which may be the same or different from one another, denote hydrogen, methyl, methoxy or chlorine and R 4 is a methyl radical which is substituted by an alkoxy radical having 1 to 6 carbon atoms
  • the alkyl radical of which may be used is additionally substituted by a chlorine atom or an alkoxy group having 1 to 2 carbon atoms in the alkyl radical, which in turn can be substituted by an alkoxy radical having 1 to 4 carbon atoms, an allyloxy radical, a cyclohexyloxy radical or a benzyloxy radical
  • R 4 means allyl or an alkyl radical having 1 to 3 carbon atoms, which is substituted by phenyl, chlorophenyl, hydroxy, alkoxy having 1 to 2 carbon atoms, dialkylamino having 1 to 2 carbon atoms in the alkyl or
  • 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 and their salts are antimicrobially active in diseases caused by bacteria and protozoa and potentiate, combined with sulfonamides, their antimicrobial action. They can 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 I and their salts can be combined with the sulfonamides mentioned by way of example in various mixing ratios, the ratio of substance according to the general formula I: sulfonamide being able to vary in the range from 1:10 to 5: 1. However, preferred mixing ratios are 1: 1 to 1: 5. As a rule, 20 to 500 mg of an active ingredient of the general formula I are suitable as doses.
  • Procedure a) is generally carried out in an aprotic diluent, such as, for example, dioxane, tetrahydrofuran, benzene, chlorobenzene, chloroform or pyridine, the reaction temperatures being between 0 and 200 ° C., depending on the reactivity of the compound of the general formula III.
  • an aprotic diluent such as, for example, dioxane, tetrahydrofuran, benzene, chlorobenzene, chloroform or pyridine
  • Procedure b) is carried out in alcohols, preferably in methanol or ethanol, or in dimethylformamide or dimethyl sulfoxide as the solvent, the reaction temperatures being between 50 and 150.degree. Temperatures around 150 ° C are required when the leaving group X is a difficult to react aliphatic amino group.
  • the leaving group in the general formula IV denotes an alkoxy group, preferably the methoxy and the ethoxy group, or a secondary aliphatic amino group, preferably a morpholino or dimethylamino group, or a primary aromatic amino group, preferably the anilino group or the imidazolyl-1 radical.
  • the 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 I 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 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 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 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.
