Abstract: Compounds of the formula: are described in which Z, Q, X, L, m and n assume the meanings stated in the description. The compounds (I) inhibit the production of TNF ? and may thus be useful in the treatment of inflammation and pathological conditions involving overproduction of said cytokine. They furthermore exhibit significant inhibitory activity on the proliferation of tumour cells and may thus be used for the treatment and/or prevention of tumorous, neurodegenerative or autoimmune disorders.

Abstract: The present invention relates to novel compounds, of the general formula (I), the N-oxide forms thereof, the salts thereof with pharmaceutically acceptable acids and the stereochemical isomers thereof, which are useful as antifungal agents; to pharmaceutical compositions containing such compounds as the active ingredient; to methods for the production of said compounds and the associated pharmaceutical compositions.
