From structure-based approach, vanillin derivatives (1) to (12) displayed some potent M inhibition against SARS-CoV-2. Favipiravir, chloroquine and hydroxychloroquine also showed some significant M inhibition. The pharmacophore modelling mode of 5RE6 displayed two Hydrogen Bond Acceptors (HBA) and one Hydrophobic (HY) interaction. Besides, the pharmacophore model of 5REX showed two HBA and two HY interactions. Finally, the pharmacophore model of 5RFZ showed three HBA and one HY interaction. Based on ligand-based approach, 20
