Abstract
In this study, a set of 234 chemical constituents reported from Goniothalamus species were docked against envelope (E), NS2B/NS3, NS5 methyltransferase, and NS5 RdRp dengue virus (DENV) protein. As the result, compounds 95, 96, 97, 100, 149, 155, and 187 were identified as potential dengue protease inhibitors based on minimal docking energy values and multiple interactions with binding sites. The results from in-silico Lipinski’ rule and ADMET analysis showed that compound 149 was predicted as the most potential compound that fulfills the drug-likeness properties. Ligand 149 was found to be able to fit in well and remain stable in the binding site of proteins envelope, NS2B/NS3, NS5 methyltransferase and NS5 RdRp. The results from molecular dynamic simulations indicate that the ligand-protein complex of 149 in NS5 methyltransferase showed the most preferable, successfully interacted within the active sites and were able to reach convergence within 100 ns.
