Revealing Potency of Bioactive Compounds as Inhibitor of Dengue Virus (DENV) NS2B/NS3 Protease from Sweet Potato (Ipomoea batatas L.) Leaves
Keywords:Dengue virus, in silico, Ipomoea batatas, protease
his study aims to identify the potency of bioactive compounds of sweet potato leaf as inhibitory agent
to dengue virus (DENV) NS2B/NS3 protease by using computational study. The 3D structure of NS2B/
NS3 protease was collected from PDB and the 2D structure of several bioactive compounds of sweet
potato leaf were obtained from PubChem. The visualization and data analysis were performed by using
the PyMol software. According to the in silico analysis, result demonstrated that dehydroabietinol had the
lowest free energy binding. However, based on the protein-ligand analysis, all the compounds showed the
hydrogen bond and hydrophobic interaction. All the compounds with hydrogen bond could not be interacted
with catalytic domain, but hydrophobic interaction could be interacted to the target domain via Ser135 by
?-Selinene and His51 by ?-Caryophyllene. In summary, we conclude that ?-Selinene and ?-Caryophyllene
might have potencies as a therapeutically drug for dengue.
