Objective: This study aims to find antimalarial candidates from 32 terpenoids and three flavonoid compounds found in miana leaves in silico using plasmepsin protein as a receptor through docking simulations, molecular dynamics simulations, and pharmacokinetic predictions.
Methods: The research was conducted in silico through molecular docking simulation, molecular dynamic simulations, analysis of potential compounds using Lipinski’s rule, and prediction of ADMET based on ligands.
Results: The results showed isophytol had the best interaction with the plasmepsin II based on the low free binding energy (FBE) and led to hydrogen bonding with the plasmepsin II crucial amino acid, Asp34. Isophytol has the best result in molecular dynamic simulation. Based on pharmacokinetics predictions, toxicity, and Lipinski’s rule of five, most tested compounds, including isophytol, meet the criteria as a promising drug.
Conclusion: Isophytol from miana leaves with plasmepsin II protein has the best and most stable interaction based on the results of molecular dynamic simulation, so this compound was a candidate for antimalarial drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
