Abstract: The present invention relates to compounds with the ability to stimulate/induce ubiquitination of a target protein/target proteins. The compounds of the present invention may stimulate/induce ubiquitination of a target protein/target proteins; i.e. via degradation of a target protein/target proteins by the cullin-RING ubiquitin ligase (CRL). Such target protein/target proteins may be proteins involved in diseases, like cancer, metabolic disorder, infectious disease and/or neurological disorder. The invention also relates to the compounds and composition for use as medicaments as well as pharmaceutical compositions comprising these compounds. Particularly, the compounds of the present invention may degrade proteins associated with cancer, metabolic disorder, infectious disease and/or neurological disorder.
