Light, molecular oxygen, and free radicals are the essence of life... for the good and the evil. They provide energy and matter for living beings, but charge a high price - diseases, ageing, death -, via electron-transfer reactions and electronic photo- and chemiexcitation of molecules. Our project concerns these processes through the study of the molecular nature of living lights (biolum…

In vivo, metabolites generated at the triplet state are endowed with the property to initiate typical photochemical reactions in the absence of light leading to loss or gain of cellular functions. This is the case of DNA Cyclobutane Pyrimidine Dimers (CPDs) recently reported to occur in melanocytes hours after UV irradiation. Electronic excitation of the DNA bases was accomplished by ener…
Quenching of triplet acetone by derivatives of sorbic acid, a conjugated diene able to halt melanocyte DNA pyrimidine dimerization in the dark. Triplet carbonyls generated in vivo are endowed with the potentiality to trigger typically photochemical reactions in the dark leading to loss or gain of cellular functions. This isthe case of DNA cyclobutane pyrimidine dimerization reported to oc…
Through thematic project "Electronic chemiexcitation in biological systems: bioluminescence and 'photo'chemistry in the dark" granted by FAPESP under case number 2017/22501-2 to the Fungi Bioluminescence Laboratory (LBF) of the Chemistry Institute/University of São Paulo (IQ-USP), two postdoctoral fellowships were offered to candidates with PhD degree. This subproject is intended to fill …
Molecular oxygen excited to its singlet state (O21Dg) stands as one of the most reactive oxygen species involved in cell damage and signal transduction. Hence the interest in unveil its biological sources, targets, and responses. This project aims to study the generation of singlet oxygen by the aerobic oxidation of formylhydrazine (formohydrazide, IUPAC) and its ±N-methyl derivative, a p…
