Metal chelators as therapeutic compounds, in particular in cancer, neurodegenerative diseases and as biostatic agents against microorganisms.

We focus on the design of powerful Fe(III) chelators of the hydroxypyridinone family that have been demonstrated by us and others to have activity as:

anticancer drugs, interfering with the biochemical processes involving metals (metalloenzymes, oxidative stress)

drugs against neurodegenerative diseases, preventing oxidative damage to neurons

biostatic agents, reducing the rate of growth of microorganisms.
