Hepatitis E Inhibited by Rosmarinic Acid Extract from Clove Plant (Syzygium Aromaricum) through Computational Analysis

Abstract

This study aims to evaluate the potential of Rosmarinic Acid as an inhibitor against Hepatitis E by interacting with the active site of the Tyrosine FYN protein. Computational approaches were employed to predict the molecular interactions between Rosmarinic Acid and Tyrosine FYN. The research methodology involved the use of software such as Pymol, Pyrex, Protein Plus, and the Lepinski Rule. Docking analysis was conducted using Pymol to obtain information about the binding energy between Rosmarinic Acid and Tyrosine FYN. The results of the analysis showed that Rosmarinic Acid exhibited a Binding Affinity of -8.3, -8, and -7.9, indicating a strong affinity towards the target protein. Additionally, Root Mean Square Deviation (RMSD) values of 0, 15.905, and 17.014 were used to assess the stability of the formed protein-ligand complex. Analysis using Protein Plus revealed interactions between Rosmarinic Acid and Tyrosine FYN. Furthermore, analysis using the Lepinski Rule to examine the physicochemical properties of Rosmarinic Acid indicated that the molecule had a mass of 360, 5 hydrogen bond donors, 8 hydrogen bond acceptors, a log P value of 1.76, and a molar reactivity of 89.8. These findings highlight the potential of Rosmarinic Acid as an inhibitor of Hepatitis E through its interaction with the Tyrosine FYN protein, providing a basis for the development of potential new therapies in the treatment of this disease.
