Anti-atherosclerotic activity of eleutherine americana merr. As the peroxisome proliferated-activated receptor γ agonist: In silico study

Peroxisome proliferated-activated receptor γ (PPARγ) has central role in Atherosclerosis process. PPARγ that is activated by ligand could inhibit atherosclerosis process through some mechanisms such as the decrease of inflammation, the increase of cholesterol efflux and stabilisation of atheroma plague. There were many research about the use of PPARγ agonist to solve the effect of and the complication of atherosclerosis especially about how to find an effective PPARγ with minimum side effect. One of the PPARγ agonists is Eleutherine americana Merr. which is a natural substance. The purpose of the study is to examine the anti-atherosclerotic activity of Eleutherine americana Merr. active substance as PPARγ agonist through in silico approach. There were 18 active substances being examined of their anti-atherosclerotic activity. Examination prediction of the anti-atherosclerotic activity was conducted through Way2Drug PASS Online. Specific docking by using Autodock Vina, 3D visualized by PyMOL(TM) 2.3.1 and the visualization of ligand-receptor was done with LigPlot+ V.2.1. The results showed that there were 4 highly potential anti-atherosclerotic substances namely eleutherinoside A, β-Sitosterol, eleuthoside B and eleutherinoside B. From the four substances, eleutherinoside A has the most negative binding affinity towards PPARγ which was-8 kcal/mol, with 8 bonds of hydrogen and was hydrophobic similar to the control substance. In conclusion, through in silico study Eleutherine americana Merr. has anti-atherosclerotic activity through the mechanism of PPARγ agonist.
