The Potential of Moringa oleifera Bioactive Compounds for Inhibiting Angiotensin-Converting Enzyme 2 Interaction in SARS-Cov-2 Syndrome

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) disease (COVID-19) is a threat to human health. This infection is determined by the interaction of the spike S1 domain protein with angiotensin-converting enzyme 2 (ACE2) in the epithelial cells of the respiratory tract, especially the lungs. ACE2 inhibition is an important target in controlling COVID-19. Flavonoids of medicinal plants, are known to interfere with ACE (ACE2 homologous). Therefore, this study aims to explore the ability of apiin, epicatechin, and hesperetin from Moringa oleifera in interacting with the ACE2 using MOE 2008.10. The ligand molecules were prepared from PubChem database. The ACE2 protein was retrieved from Protein Data Bank (ID 1R4L) and analyzed for the active sites. Analysis of docking scores and hydrogen bonds of ACE2-ligand complex and active site showed that the affinity of flavonoids can be ranked as hesperetin > epicatechin > apiin > C19H23Cl2N3O4. The results provided computational information that apiin, epicatechin, and hesperetin have the potential to prevent COVID-19 infection. The prediction of activity spectra for substances (PASS) score showed the ligand displays antiviral activity.

Infeksi severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pada pandemi coronavirus disease 2019 (COVID-19) menjadi ancaman dunia kesehatan saat ini. Infeksi SARS-CoV-2 ditentukan oleh interaksi protein spike envelope S1 domain dengan reseptor angiotensin-converting enzyme 2 (ACE2) yang diekspresikan pada sel epitel saluran pernafasan terutama paru-paru. Mekanisme penghambatan ACE2 menjadi target penting dalam pengendalian COVID-19. Senyawa bioaktif tanaman obat, seperti flavonoid diketahui mampu mengganggu fungsi banyak makromolekul termasuk ACE (homolog dengan ACE2). Penelitian ini bertujuan mengeksplorasi kemampuan senyawa apiin, epicatechin, dan hesperetin dari Moringa oleifera dalam berinteraksi dengan sisi aktif ACE2 menggunakan metode penambatan molekul. Studi dilakukan dengan preparasi struktur molekul ligan dari PubChem database dan diolah dengan MOE 2008.10. Selanjutnya, data protein ACE2 (Protein Data Bank ID 1R4L) dianalisis sisi aktifnya untuk mengetahui lokasi penambatan ligan senyawa. Analisis skor docking dan ikatan hydrogen komplek ligan dan sisi aktif ACE2 menunjukkan bahwa afinitas flavonoid dapat diperingkatkan sebagai afinitas hesperetin > epicatechin > apiin > C19H23Cl2N3O4. Ketiga ligan senyawa yang terkandung dalam M. oleifera secara in silico mampu mengikat sisi aktif ACE2, sehingga berpotensi mencegah infeksi COVID-19. Skor PASS (prediction of activity spectra for substances) menunjukkan aktivitas biologis ligan yang menyerupai antiviral.
