metadata.dc.description.resumo: In this paper, we evaluated the drug-receptor interactions responsible for the antimicrobial activity of thymol, the major compound present in the essential oil (EO) of Lippia thymoides (L. thymoides) Mart. & Schauer (Verbenaceae). It was previously reported that this EO exhibits antimicrobial activity against Candida albicans (C. albicans), Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli). Therefore, we used molecular docking, molecular dynamics simulations, and free energy calculations to investigate the interaction of thymol with pharmacological receptors of interest to combat these pathogens. We found that thymol interacted favorably with the active sites of the microorganisms’ molecular targets. MolDock Score results for systems formed with CYP51 (C. albicans), Dihydrofolate reductase (S. aureus), and Dihydropteroate synthase (E. coli) were −77.85, −67.53, and −60.88, respectively. Throughout the duration of the MD simulations, thymol continued interacting with the binding pocket of the molecular target of each microorganism. The van der Waals (∆EvdW = −24.88, −26.44, −21.71 kcal/mol, respectively) and electrostatic interaction energies (∆Eele = −3.94, −11.07, −12.43 kcal/mol, respectively) and the nonpolar solvation energies (∆GNP = −3.37, −3.25, −2.93 kcal/mol, respectively) were mainly responsible for the formation of complexes with CYP51 (C. albicans), Dihydrofolate reductase (S. aureus), and Dihydropteroate synthase (E. coli).
Abstract: Neste artigo, avaliamos as interações fármaco-receptor responsáveis pela atividade antimicrobiana do timol, o principal composto presente no óleo essencial (EO) de Lippia thymoides (L. thymoides) Mart. & Schauer (Verbenaceae). Foi relatado anteriormente que este EO exibe atividade antimicrobiana contra Candida albicans (C. albicans), Staphylococcus aureus (S. aureus) e Escherichia coli (E. coli). Portanto, usamos docking molecular, simulações de dinâmica molecular e cálculos de energia livre para investigar a interação do timol com receptores farmacológicos de interesse para combater esses patógenos. Descobrimos que o timol interagiu favoravelmente com os sítios ativos dos alvos moleculares dos microrganismos. Os resultados do MolDock Score para sistemas formados com CYP51 (C. albicans), Diidrofolato redutase (S. aureus) e Diidrofolato sintase (E. coli) foram −77,85, −67,53 e −60,88, respectivamente. Durante toda a duração das simulações MD, o timol continuou interagindo com o bolso de ligação do alvo molecular de cada microrganismo. As energias de interação de van der Waals (∆EvdW = −24,88, −26,44, −21,71 kcal/mol, respectivamente) e eletrostáticas (∆Eele = −3,94, −11,07, −12,43 kcal/mol, respectivamente) e as energias de solvatação não polares (∆GNP = −3,37, −3,25, −2,93 kcal/mol, respectivamente) foram as principais responsáveis pela formação de complexos com CYP51 (C. albicans), Diidrofolato redutase (S. aureus) e Diidropteroato sintase (E. coli).
