The study of proteins and mechanisms involved in the apoptosis and new knowledge about cancer's biology are essential for planning new drugs. Tumor cells develop several strategies to gain proliferative advantages, including molecular alterations to evade from apoptosis. Failures in apoptosis could contribute to cancer pathogenesis, since these defects can cause the accumulation of dividi…
This project aims to continue the work begun with the thematic project "Photosensitization in Life Sciences" and to maintain the collaboration with experimental and also with computational simulation researchers in the development of photosensitizers, focusing mainly on photodynamic therapy. Methods based on density functional theory will be employed to study the fundamental, excited and …

This project aims to model carbon quantum dots (CQDs), focusing on variations in their absorption spectra resulting from doping with different proportions of oxygen, nitrogen, and boron. Molecular stacking simulations and calculations of the optical emission properties of CQDs will also be performed. The research will be carried out using computational chemistry methods, particularly Dens…
Alzheimer's disease (AD) can be described as a progressive neurodegenerative disorder. This condition has reached alarming epidemic proportions due to the aging global population. Worldwide, about 50 million people suffer from dementia, and the forecast is that this number will more than triple by 2050 as the population ages. Dementia affects millions of people globally, with the majority…
The photodynamic therapy (PDT) is a noninvasive and selective treatment for cancer and otherdiseases. The excitation of a photosensitizer by a laser with a specific wavelength. This excitedphotosensitizer can react with oxygen present in biological systems, generating reactive oxygenspecies (ROS) and triggering cellular damage. To do so, the photosensitizer must undergo anIntersystem Cros…
This project is derived of a collaboration with the Federal University of Maranhão, in which there is a wide range of phytosanitary (herbicides, fungicides and insecticides) to be studied. Agrochemicals are substances used in agriculture with the aim of combating undesirable species that may interfere with the growth process of plantations. However, their exorbitant use can generate major…
In this project, the study of electronic properties of insecticides used in the agricultural production of the Balsas and Tocantins Rivers is proposed, aiming at the development of sensors. This project is part of a collaborative initiative with the Federal University of Maranhão, in which there is a wide range of agrochemicals (herbicides, fungicides and insecticides) that we intend to s…
To elucidate and understand the photophysical and energy transfer processes of potential photosensitizers for photodynamic therapy, computational studies for compounds derived from anthocyanin, anthraquinone and porphyrin will be carried out. DFT and TD-DFT approaches will be employed mainly in optimizing the geometry of the molecules, obtaining absorption spectra, electronic transitions …

Photodynamic therapy (PDT) consists of applying light with precise energy in the presence of a photosensitizer (PS) and molecular oxygen to promote cell death. Since the efficacy of PS to be employed in PDT will depend, among other factors, on the transfer of energy to molecular oxygen, longer excited-state lifetimes and the environmental effects may favor this process. Here we propose to…
