Abstract

Spike protein is a receptor protein that has e role in the entry step of SARS-CoV2. This protein will bind to the ACE2 receptor in the human body and activate TMPRSS2. Inhibition of this protein will prevent the binding of the virus to host cells to spread the infection. This study aims to identify the activity of bioactive compounds of Merremia mammosa (Lour) tuber obtained from LC-MS/MS QTOF analysis of a previous study against the Spike protein of SARS-CoV2 using molecular docking and ADMET analysis. Molecular docking was conducted using SARS-CoV2 spike protein (PDB id. 6M0J) using Maestro Schrodinger software. Results showed that from 206 compounds there are 8 compounds of Merremia mammosa (Lour) that have lower predictive binding energies than standard drugs arbidol, hydroxychloroquine, and chloroquine. Result: 206 compounds of Merremia mammosa (Lour) tuber were successfully docked, there were 8 compounds that have docking scores more negative than standard drugs. It indicates that 8 compounds are more active than the positive controls. ADMET study revealed all of those potential ligands had the possibility to be developed as drugs. Conclusion: Molecular docking simulations were successfully utilized to identify the potential compounds from Merremia mammosa (Lour) tuber with the activity as an inhibitor for spike protein of SARS-CoV2. Further in vitro assay and purification are needed for future research.
