Daun salam (Syzygium polyanthum) diidentifikasi memiliki senyawa aktif
flavonoid. Flavonoid dilaporkan memiliki aktivitas antivirus. SARS-CoV-2
merupakan virus dari penyakit COVID-19. Virus ini dapat ditularkan dari manusia
ke manusia. SARS-CoV-2 memiliki beberapa komponen penting salah satunya
yaitu 3C-Like Protease. 3C-Like Protease berperan penting terhadap replikasi
coronavirus. Penelitian ini bertujuan mempelajari interaksi antara senyawa
flavonoid Daun salam (Syzygium polyanthum) dalam menghambat 3C-like
Protease SARS-CoV-2 melalui uji in silico menggunakan teknik penapisan virtual
serta memprediksi kemampuannya untuk dijadikan sediaan obat oral dengan
memprediksi sifat bioavailabilitas dan toksisitasnya. Potensi terbaik terlihat pada
Quercitrin dan Myricitrin dengan masing-masing ΔG -8.926 kkal/mol dan -8.858
kkal/mol. Dua senyawa tersebut memiliki berbagai interaksi ikatan hidrogen dan
hidrofobik terhadap asam amino pada reseptor, serta diprediksi memiliki
bioavailabilitas yang cukup baik dan tidak bersifat toksik, sehingga dapat menjadi
kandidat inhibitor potensial enzim 3C-like Protease SARS-CoV-2 untuk dijadikan
sediaan obat oral dalam menangani pandemik COVID-19. Bay leaf (Syzygium polyanthum) has been identified to have active
flavonoid compounds. Flavonoids are reported to have antiviral activity. SARSCoV-2 is a virus from the COVID-19 disease. This virus can be transmitted from
human to human. SARS-CoV-2 has several important components, one of which is
3C-Like Protease. 3C-Like Protease plays an important role in coronavirus
replication. This research aims to study the interaction of flavonoid compounds in
bay leaf (Syzygium polyanthum) in inhibiting the 3C-like Protease SARS-CoV-2
through in silico analysis using virtual screening techniques and predicting its
ability to be used as an oral drug candidate by predicting its bioavailability and
toxicity. The best potency was found in Quercitrin and Myricitrin with ΔG value of
-8,926 kcal/mol and -8,858 kcal/mol, respectively. The two compounds have
various hydrogen bondings and hydrophobic interactions with the amino acid
residues of the receptor and are predicted to have good bioavailability and non-toxic
properties so that they become potential inhibitors of 3C-Like Protease of SARSCoV-2 as oral drug candidate in dealing with the COVID-19 pandemic
