The present invention is based on the finding that the compounds disclosed herein bind to, preferably harmful, protein-oligomers and thereby induce a conformational change of the latter. This conformational change enhances the recognition of the protein oligomers by cellular degradation mechanisms, such as autophagy and the ubiquitin proteasome system which in turn causes an increased degradation of such, usually undesireous, protein-oligomers. Hence, in a first aspect, the invention pertains to a protein-oligomer aggregation-agent, wherein the protein-oligomer aggregation-agent comprises, or is selected from, a small molecule, an antibody, a nanoparticle, a nucleic acid, a peptide and/or a therapeutic protein. The invention provides therapeutic applications of the disclosed compounds in the treatment and/or prevention of disorders associated with the presence of one or more of such oligomeric structures, preferably of protein-oligomers. The invention intends to induce aggregation of harmful oligomers and thereby induce cellular systemic mechansims that recognize and degrade structurally larger aggregates.

Methods of treating polyQ diseases or disorders such as Huntington's Disease are presented. Compounds of formula (I) of the disclosure are capable of binding directly to the polyQ segment of mutated huntingtin. This binding results in at least partial reversal of the conformation of mutated huntingtin to wild type huntingtin. The binding also facilitates autophagic removal of misfolded and/or mutated proteins such as mutated huntingtin.
