During my experimental thesis I synthesized and characterized 5 ligands in which the main scaffold is similar to curcumin setting up the procedure to introduce various groups and atoms in position 9 of these curcumin-like ligands. Obtaining three new ligands, two of which reacted with 123I in order to give a radiolabeled curcumin. This radiolabeled curcumin was then administered in mice during in-vivo tests and its bioaccumulation was followed with PET device to check its binding with β-amyloid plaques. Moreover I synthesized and characterized a Ruthenium p-cymene complex containing the iodo-curcumin. On this complex were then realized in-vitro cytotoxicity and antioxidant activity tests that showed how the presence of these functionalization on the aromatic moiety lead to a lower activity of the complex itself. It could anyway interesting to evaluate through the use of a PET device its in-vivo biodistribution and accumulation at a systemic level in order to confirm or not the loss of this activity.
