Metal-Complexes Bearing Releasable CO Differently Modulate Amyloid Aggregation.

ABSTRACT: Neurodegenerative diseases are often associated with an uncontrolled amyloid aggregation. Hence, many studies are oriented to discover new compounds that are able to modulate self-recognition mechanisms of proteins involved in the development of these pathologies. Herein, three metal-complexes able to release carbon monoxide (CORMs) were analyzed for their ability to affect the self-aggregation of the amyloidogenic fragment of nucleophosmin 1, corresponding to the second helix of the three-helix bundle located in the C-terminal domain of the protein, i.e., NPM1_264-277, peptide. These complexes were two cymantrenes coordinated to the nucleobase adenine (Cym-Ade) and to the antibiotic ciprofloxacin (Cym-Cipro) and a Re(I)-compound containing 1,10-phenanthroline and 3
