Abstract

Curcumin, a yellow pigment extracted from the Indian spice Curcuma longa, has been widely linked with suppression of angiogenesis, inflammation, cardiovascular diseases, tumorigenesis and A-binding activities in the context of therapies for Alzheimer’s disease [1,2]. Besides, Curcumin has shown interesting binding ability towards different metal ions such as Fe(III) and Ga(III) with the involvement of its keto-enolic moiety [3]. Metal complexation triggers an increased kinetic stability and bioavailability of Curcumin in physiological conditions, reducing one of its main drawbacks in therapeutic applications. Anyway biologically active curcuminoids have little been investigated as labelled radiopharmaceuticals for cancer diagnosis or therapy, and they represent a novelty in the field. In this presentation we show an overview of new classes of Curcumin-based ligands with bidentate and tridentate coordinating mode, we investigate their binding ability towards Rhenium and Gallium and report a complete thermodynamic and pharmaco-kinetic study on ligands and metal complexes with the aim of developing new radiopharmaceuticals.
