  • Patent number: 8492537
    Abstract: The invention relates to special nucleosides, for example, a nucleoside of the formula I, wherein R1-R5 are as described herein, and also to drugs which contain these nucleosides. Furthermore, the invention relates to the use of such nucleosides in a method for suppressing or reducing the formation of resistance in the case of cytotstatic treatment of a cancer patient.
    Type: Grant

  • Patent number: 5684160
    Abstract: The invention is directed to 3-aminopyrroles of formula I, which are largely new, to methods for the preparation and to their use as medicinal agents and preparations, as well as to anti-convulsive or analgesic preparations containing these 3-aminopyrroles.Disubstituted and monosubstituted amino groups are claimed as 3-amino substituents.The invention pursues the objective of developing largely new 3-aminopyrroles, which have CNS activity, particularly ones which anti-convulsive or analgesic properties, as well as methods for their preparation and their use as medicinal preparations.Pursuant to the invention, the synthesis is carried out by cyclizing open-chain precursors, such as aminoacrylic acid derivative, or by modifying pyrroles.
