Antiviral Activities of Compounds Derived from Medicinal Plants against SARS-CoV-2 Based on Molecular Docking of Proteases
Bibliographic record
Abstract
This work aimed to evaluate the inhibitory effect of the main polyphenols and flavonoids of Syzygium aromaticum and Citrus limon as well as the main organosulfur compounds of Allium sativum against SARS-CoV-2 6LU7 and 6Y2E proteases using in silico molecular docking analysis. Structures of 34 natural products found in three medicinal plants were docked to these two critical proteins. For 6LU7 protease, 24 compounds exhibited binding affinities greater than or equal to -6 Kcal/mol. While, for 6Y2E protease, 6 compounds exhibited binding affinities greater than or equal to -6 Kcal/mol. Molecules with a maximum binding affinity equal to -8.4 kcal/mol show good hydrogen bonds with the two proteases under investigation, 6LU7 and 6Y2E. Diosmin, ellagic acid, narirutin, neoeriocitrin, and neohesperidin were suggested as inhibitors of SARS-COV-2. These compounds might be used therapeutically as complementary medicines and/or to conceptualize new drugs against COVID-19.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
