Dissertação (Mestrado em Ciências Farmacêuticas) - Faculdade de Farmácia, Universidade Federal de Goiás, Goiânia, 2023.http://repositorio.bc.ufg.br/tede/handle/tede/13333This study employs electrochemical and Density Functional Theory (DFT) calculation approaches to investigate the potential of a novel analogue of trimetozine (TMZ) antioxidant profile. The correlation between oxidative stress and psychological disorders indicates that antioxidants may be an effective alternative treatment option. Butylatedhydroxytoluene (BHT) is a synthetic antioxidant widely used in industry. The BHT-TMZ compound derived from molecular hybridization, known as LQFM289 (Cabral et al., 2023), has shown promising results in early trials, and this study aims to elucidate its electrochemical properties to further support its potential as a therapeutic agent. The electrochemical behavior of LQFM289 was investigated using cyclic voltammetry (CV), square wave voltammetry (SWV), and differential pulse voltammetry (DPV), and a mechanism for the redox process was proposed based on the compound’s behavior. LQFM289 exhibits two distinct oxidation peaks: the first peak, (Ep1a ≈ 0.49V), corresponds to the oxidation of the phenolic fraction (BHT), and the second peak, (Ep2a ≈ 1.2 V vs. Ag/AgCl/KClsat), denotes the oxidation of the amino group from morpholine.Electroanalysis was used to identify the redox potentials of the compound, providing insight into its reactivity and stability in different environments. A redox mechanism was proposed based on the resulting peak potentials. The DFT calculation elucidates the electronic structure of LQFM289, resembling the precursors of molecular hybridization (BHT and TMZ), which may also dictate the pharmacophoric performance.Attribution-NonCommercial-NoDerivatives 4.0 InternationalDescoberta de drogasAnsiedadeantioxidanteMecanismo de oxidaçãoButilhidroxitoluenoDrug discoveryAnxietyAntioxidantOxidation mechanismButylhydroxytolueneCIENCIAS DA SAUDE::FARMACIADissertação
