Resumo: | In this work, a new serie of 1,10-phenanthroline-4,5-imidazo-benzochalcogenazoles 5a-h/ 6a-g obtained through the Debus-Radziszeski condensation was synthesized. Benzoxazoles and benzothiazoles were previously synthesized and derivatives 1,10- phenanthroline-4,5-imidazo-benzochalcogenazoles 5a-h/ 6a-g were obtained with yields ranging from 43 to 85%. The photophysical properties of compounds 5a-h/ 6a-g were evaluated against UV-Vis absorption, fluorescence emission and quantum yield fluorescence. Regarding the absorption spectrum of the derivatives, they had their spectra reported in the ultravioleta region and the fluorescence emission the compounds was observed in the purple to blue region. The quantum yield fluorescence (Φf) ranged from 0,10 – 0,71. The analyses of the biological activity about derivatives were carried out in silico, through molecular anchorage and in live, against the protease MPRO of the SARS-CoV-2 virus, which causes the disease COVID 19. The results of molecular anchorage demonstrate high affinity of the derivatives with the active place of the protease M. Additionally, the activity of these compounds as inhibitors of SARS-CoV2 was evaluated in vitro, and the compunds showed a very significant viral inhibition rate, with EC50 of 0,17 – 0,19 µM. |

Os benzoxazóis e benzotiazóis foram previamente sintetizados e os derivados 1,10-fenantrolina-4,5-imidazo-benzocalcogenazois 5a-h/6a-g foram obtidos com rendimentos que variaram de 43-85%. As propriedades fotofísicas dos compostos 5a-h e 6a-g foram avaliadas frente a absorção UV-Vis, emissão de fluorescência e rendimento quântico de fluorescência. Em relação ao espectro de absorção dos derivados, estes tiveram seus espectros relatados na região do ultravioleta e a emissão de fluorescência dos compostos foi observada na região do roxo a azul. Já o rendimento quântico de fluorescência (Φf) variou de 0,03-0,75. As análises de atividade biológica dos derivados foram realizadas in silico, através de ancoragem molecular e frente a protease MPRO do vírus SARS-CoV-2, causador da doença COVID 19. Os resultados da ancoragem molecular demonstram alta afinidade dos derivados 5a-h/6a-g com o sítio ativo da protease M. Adicionalmente, a atividade destes derivados como inibidores da SARS-CoV-2 foi avaliada in vitro, sendo que os compostos apresentaram uma taxa de inibição viral bastante significativa, com EC50 de 0,17 – 0,19 µM.Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e ExatasRodrigues, Oscar Endrigo Dorneleshttp://lattes.cnpq.br/6536519955416085Dornelles, LucianoDalcol, Ionara IrionVargas, JosimarVilletti, Marcos AntonioMiranda, Milene DiasSarturi, Joelma Menegazzi2022-10-31T13:16:28Z2022-10-31T13:16:28Z2022-08-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/26705porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2022-10-31T13:16:28Zoai:repositorio.ufsm.br:1/26705Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-10-31T13:16:28Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
