metadata.dc.description.resumo: The essential oil of Siparuna guianensis was obtained by hydrodistillation. The identification of the chemical compounds was performed by gas chromatography coupled with mass pectrometry (GC/MS). Antimicrobial activity was investigated for four microorganisms: Streptococcus mutans (ATCC 3440), Enterococcus faecalis (ATCC 4083), Escherichia coli (ATCC 25922), and Candida albicans (ATCC-10231). The studies of doping and molecular dynamics were performed with the molecule that presented the highest concentration of drug–target proteins, 1IYL (C. albicans), 1C14 (E. coli), 2WE5 (E. faecalis), and 4TQX (S. mutans). The main compounds identified were: Curzerene (7.1%), -Elemene (7.04%), Germacrene D (7.61%), trans-β-Elemenone (11.78%), and Atractylone (18.65%). Gram positive bacteria and fungi were the most susceptible to the effects of the essential oil. The results obtained in the simulation showed that the major compound atractylone interacts with the catalytic sites of the target proteins, forming energetically favourable systems and remaining stable during the period of molecular dynamics.
Abstract: O óleo essencial de Siparuna guianensis foi obtido por hidrodestilação. A identificação dos compostos químicos foi realizada por cromatografia gasosa acoplada à espectrometria de massas (GC/MS). A atividade antimicrobiana foi investigada para quatro microrganismos: Streptococcus mutans (ATCC 3440), Enterococcus faecalis (ATCC 4083), Escherichia coli (ATCC 25922) e Candida albicans (ATCC-10231). Os estudos de dopagem e dinâmica molecular foram realizados com a molécula que apresentou maior concentração de proteínas alvo do fármaco, 1IYL (C. albicans), 1C14 (E. coli), 2WE5 (E. faecalis) e 4TQX (S. mutans). Os principais compostos identificados foram: Curzereno (7,1%), -Elemeno (7,04%), Germacreno D (7,61%), trans-β-Elemenona (11,78%) e Atractilona (18,65%). Bactérias Gram positivas e fungos foram os mais suscetíveis aos efeitos do óleo essencial. Os resultados obtidos na simulação mostraram que o composto majoritário atractilona interage com os sítios catalíticos das proteínas alvo, formando sistemas energeticamente favoráveis ​​e permanecendo estáveis ​​durante o período de dinâmica molecular.
