Abstract: The invention relates to the use of substituted bicyclo[3.3.1]nonan-2,4,9-triones, especially clusianon and clusianon derivatives, as pharmaceutical active ingredients or medicamentous active ingredients, especially for producing medicaments for the prophylactic and/or therapeutic (curative) treatment of tumour or cancer diseases, and of viral diseases. The above-mentioned compounds can be used in cytostatic agents and antiviral agents (virostatic agents). They are especially used as inhibitors of topoisomerases and telomerases and as regulators during the MAP kinase signal transduction and can thus intervene on a cellular scale in the mechanism for multiplication of tumour or cancer cells and viruses.

Abstract: The invention relates to a clusianon isomer and to the use thereof, in particular as a pharmaceutical or medical active ingredient, in particular for producing medicaments for the prophylactic and/or therapeutic (curative) treatment of tumor or cancer diseases as well as viral diseases. The aforementioned compound can be used in cytostatics and antiviral agents (virostatics). Said compound acts, in particular, as a topoisomerase and telomerase inhibitor and as a regulator in the MAP kinase signal transduction. Said compound can thus intervene at the cellular level in the proliferation mechanism of tumor or cancer cells and viruses.
