Definitions
- the invention relates to new 4-amino-1-aryl-pyrid-2-one, processes for their preparation and their use as medicaments, in particular for the treatment of various forms of epilepsy
- the invention is therefore based on the object of making available new compounds with favorable pharmacological properties which can be used in particular as medicaments having an antiepileptic effect
- these new compounds are 4-amino-1-aryl-pyrid-2-one of the general formula 1
- X hydrogen, C-
- -C4-alkoxy, T ⁇ fluormethyl, T ⁇ fluormethoxy or halogen and A amino, C-
- the compounds of general formula 1 can by a new method by reacting the compounds of general formula 2
- X hydrogen, -C -C 4 alkyl, C-
- R C 1 -C 4 alkyl
- Py ⁇ midine derivatives of the general formula 2 can be synthesized in a simple manner (Chem Heterocycl Compd, 24 (8), (1988), 914-919, Khim Geterotsikl Soedin, 8, (1988), 1109-1114)
- the compounds of the general formula 1 are prepared in two process stages, py ⁇ midine derivatives of the general formula 2 in an alkaline medium, preferably in 5 to 50 percent sodium hydroxide solution, 0.1 to 10 hours, preferably one hour, at 50 ° C. to 150 ° C.
- the mixture is then heated to 100 ° C. to 200 ° C. with strong acids, preferably 50 to 98 percent sulfuric acid, for 10 to 30 minutes by known methods.
- the primary amino group can be mono- or dialkylated using known methods , 4-D ⁇ brombutan, 1, 5-D ⁇ brompentan or D ⁇ - (2-chloroethyl) ether
- the compounds of general formula 1 according to the invention are suitable for the preparation of pharmaceutical compositions. These pharmaceutical compositions contain at least one of the compounds of general formula 1 according to the invention
- the medicaments can be used, for example, parenterally (for example intravenously, intramuscularly subcutaneously) or orally.
- parenterally for example intravenously, intramuscularly subcutaneously
- the appropriate forms of application are produced by methods which are generally known and customary in pharmaceutical practice
- the compounds according to the invention were in vivo after ip application to mice or after (po application) to rats according to the international standard (Pharmac Weekblad, Sc Ed 14, 132 (1992) and Antiepileptic Drugs, Third Ed, Raven Press, New York 1989) tested for their anticonvulsant activity (Table 1)
- known antiepileptics either work in the model maximum electric shock only at higher doses or have stronger, undesirable (neurotoxic) side effects
- a 4-aminopyridin-2-one (example 1-15) prepared according to the general synthesis instructions is alkylated with a suitable alkylating agent such as dimethyl sulfate or di (2-chloroethyl) ether in the presence of sodium methylate.
- a suitable alkylating agent such as dimethyl sulfate or di (2-chloroethyl) ether in the presence of sodium methylate.
- the reaction mixture is introduced into water.
- the precipitate is separated off and recrystallized.
