Research Interests

Radi´s research activities have focused on the biochemistry, cell biology, relevance to disease mechanisms and therapeutics of free radicals, oxidants and antioxidant systems. In particular, Radi has contributed to clarify the mechanisms of nitric oxide-dependent toxicity through its interaction with superoxide and the formation of peroxynitrite in vitro and in vivo. He has extensively characterized the biological chemistry of peroxynitrite, including the discovery of free radical-dependent and independent reaction pathways, its impact in mitochondrial dysfunction and apoptosis via oxidation and nitration reactions and its role in pathology. He has contributed to the concept that an oxidizing environment can "shift" the physiological actions of nitric oxide towards pathophysiology. Radi's work facilitated the development, testing and chemical characterization of antioxidants that serve as peroxynitrite decomposition catalysts as well as mitochondrial-targeted redox-based drugs for application in cardiovascular, neurodegenerative and inflammatory conditions. Additionally, Radi has shown that peroxynitrite is a cytotoxic effector in cellular immune responses against intracellular pathogens such as the causative agent of Chagas disease, Trypanosoma cruzi, and how microbial antioxidant systems constitute virulence factors. He has authored over 210 peer-review papers and 40 reviews, with an h-index = 72 (ISI, Feb 2016) and over 22,000 citations.
