Abstract
Objective: The present study is an in silico model of platelet amplification potential of
Adhatoda vasica, which can be used to treat thrombocytopenia in dengue complications.
Methods: Docking studies have proved to be an essential tool that facilitates the structural diversity of
natural products to be harnessed in an organized manner. In the present study, vasicine containing natural
anti-dengue potential was subjected to docking studies using Schrodinger glides software
(ver.11.1). The docking study was carried out to find out the potential molecular targets for selected
protein. The docking was carried out on different ligands, like vasicine, ramatroban, chloroquine,
celgosivir, and standard eltrombopag downloaded from PubChem and retrieved to glide software and
ligands prepared using lig prep wizard. Docking was performed using the ligand docking wizard of
Glide-maestro 2018.
Results: The docking score of vasicine (-5.27) is nearly identical to the standard eltrombopag (-6.08),
and both ligands bind with one hydrogen bond. The validation score of ramatroban is -12.39, binding
with five hydrogen bonds, Celgosivir exhibited a docking score of -7.3 with three hydrogen bonds, and
chloroquine displayed no hydrogen bond but had a docking score of -4.6.
Conclusion: Vasicine was found to be the most suitable target of platelet amplification potential from
Adhatoda vasica. However, the molecular docking results are preliminary, and it has been indicated
that vasicine could be one of the potential ligands to treat the thrombocytopenia of dengue; experimental
evaluation will be carried out in the near future.
