The present invention relates to the field of protein misfolding diseases and thus to diseases which are associated with or induced by abnormal or pathogenic three-dimensional folding of proteins and/or peptides or which are linked to pathogenic conformational changes of proteins and/or peptides, such as Alzheimer's disease. Particularly, the present invention provides novel trimeric pyrazole compounds, which exhibit a therapeutic effectiveness in regard to the aforementioned protein misfolding diseases, and refers to their use for the treatment of such protein misfolding diseases, especially neurodegenerative diseases as well as to medicaments or pharmaceutical compositions comprising these compounds.
