| Summary: | Severe Acute Respiratory Syndrome (SARS) is a respiratory infectious disease caused by SARS-CoV that
spreads so fast in 2003. In December 2019, a new infectious outbreak called as Corona Virus Disease
2019 (COVID-19) caused by SARS-CoV-2 emerged. There has been no specific therapy or drug approved
to treat human coronavirus. Natural product could become an alternative therapy for COVID-19 and
SARS. Pomegranate (Punica granatum L.) was reported to show antiviral effect. This research aims to
??±¸ð®????±ã? ? ?± ?±±??????®??????¸ as inhibitor candidate for SARS-CoV and SARS-CoV-2 proteases,
and predict their toxicity. Proteins used in this study are SARS-CoV-2 main protease or 3-chymotripsinlike protease (PDB ID: 6LU7), SARS-CoV main protease (PDB ID: 2ZU5) and SARS-CoV papain-like
protease (PDB ID: 4OW0). Compound?????????????structures were made with Gaussiew 5.0 and optimized by
Gaussian 09W. After the docking was validated, compounds were docked into target protein using
AutoDock v.4.2.3. The docking results were evaluated by using Discovery Studio. Toxicity prediction
was performed by using ECOSAR and Toxtree. The compunds were predicted as inhibitor candidate
based on amino acid residue and energy binding are ellagic acid with binding energy -10,12 Kcal/mol
for main protease SARS-CoV-2, and gallocathecin with binding energy -11,99 Kcal/mol for main
protease and -10,51 Kcal/mol for papain-like protease SARS-CoV. Ellagic acid and g ???® ?í±®ð??????
