Grupo de Investigación en Fotoquímica y Reactividad de Pteridinas

Welcome to the webpage of the Photosensitization and Molecular Photobiology Research Group. Our work concentrates on the study of the photochemistry and photophysics of pteridines, with emphasis on the photosensitizing properties, production of reactive oxygen species and reactivity towards oxidizing agents. Pteridines are present in biological systems in multiple forms and play different roles ranging from pigments to enzymatic cofactors for numerous redox and one-carbon transfer reactions. Pteridines have a profuse and amazing photochemistry: under UV-A excitation (320-400 nm), these biomolecules can fluoresce, undergo chemical reactions, such as oxidation and dimerization, and generate reactive oxygen species such as singlet oxygen (1O2).

Our group works at the The Research Institute of Theoretical and Applied Physical Chemistry (INIFTA) The Research Institute of Theoretical and Applied Physical Chemistry (INIFTA) at La Plata, Buenos Aires, Argentina. This Institute is part of the Department of Chemistry of the National University of La Plata (UNLP) and the National Scientific and Technical Research Council (CONICET) of Argentina.
