Abstract

Ebola hemorrhagic fever (EHF) is a fatal disease caused by Ebolavirus that can potentially lead to
death. The number of fatalities reached 11.000 of the 28.000 reported cases. A serious concern should be taken
because neither drug nor treatment to cure this disease has been found until now. Recent studies show that viral
protein 24 (VP24) is one of the non-structural protein that plays a key role in EBOV proliferation and viral life
cycle. This study tried to find the potential inhibitor for EBOV VP24 through in silico experiment. About
242.520 compounds from ZINC15 In Vitro Database were obtained and screened according to the Rules of
Three and pharmacological properties to get a proper lead-like fragment compounds. These compounds were
docked into the active site of VP24 using MOE 2014.09 software. The potential fragment compounds were
linked to generate potential inhibitor ligands. These ligands were screened earlier based on Lipinski’s Rule of
Five and toxicity prediction, then they were docked once again to obtain the favorable ligand. Furthermore, the
dynamics simulation of best ligand, namely L833, L217, and L595, were performed to predict the ligand-enzyme
complex stability. This research concludes that L595 is the best ligand. Moreover, the pharmacological and
toxicity prediction also confirm that L595 can be developed as the potential inhibitor for EBOV VP24.
