Docking Approach

Corona virus is one of the significant pathogens that destructs the human respiratory functioning. Deaths and casualties caused by coronaviruses (CoVs) include the severe acute respiratory syndrome (SARS)-CoV and the Middle East respiratory syndrome (MERS)-CoV. The aim of the work was to compare several antiviral drugs and find out which is the most active drug that might be used in treatment for COVID -19. In this study Molecular Docking approach was used to determine the binding affinities of 62 antiviral molecules. The study was carried out using Molegro Virtual Docker 6.0 with PDB 2GTB procured from RCSB Protein Data Bank. Simeprevir and Telaprevir were discovered to be most potent having high MolDock and Rerank scores of -225.158, -78.4383 and -209.467, -136.155 respectively. Further studies may be conducted to design more potent analogue and defeat COVID-19.

In the present study, the interaction of the protein structure of Escherichia coli DNA Gyrase-A (EcGyr-A) extracted from protein data bank (PDB Code: 1AB4) with ligands N-ferrocenylmethyl-2-nitroaniline (2FMNA), N-ferrocenylmethyl-3-nitroaniline (3FMNA) and N-ferrocenylmethyl-4-nitroaniline (4FMNA) were investigated by performing docking studies using the Molegro Virtual Docker (MVD) software. The results obtained showed that the best poses which is derived from MolDock score for Escherichia coli DNA Gyrase-A were respectively equal to-92.0111, -96.0866 and-95.6808 with reranking score equal to-40.9575, -73.4476 and-73.6423. Calculations revealed that 3FMNA react strongly with EcGyr-A followed by 4-FMNA and 2-FMNA.

AbstractBackgroundPBP2a is a type of penicillin-binding proteins (PBPs) that cause resistivity in methicillin-resistant Staphylococcus aureus (MRSA) from β-lactam antibiotics. MRSA susceptible with cefttobiprole (fifth generation of cephalosporin as an anti-MRSA agent) which inhibits PBP2a and stops its growth. Contrary to its efficacy, ceftobiprole causes taste disturbance more than any other cephalosporins; furthermore, its mechanism is unknown. This study aims to explore an in silico study of a natural compound, which serves as a potential alternative to overcome MRSA with minimum adverse side effects.MethodsA molecular docking study was performed using Molegro Virtual Docker version 5.5. Brazilin and proto-sappanins A–E are phytochemical compounds contained in sappan wood extract and are docked into the binding site of PBP2a (Protein Data Bank: ID 4DKI).ResultsBrazilin and proto-sappanins A–E have some interaction with Ser 403 amino acid residue which is an important interaction to inhibit PBP2a protein. The result of the molecular docking study showed that the MolDock score of proto-sappanins D and E is lower than that of methicillin but higher than that of its native ligand (ceftobiprole).ConclusionsThe results of this study suggest that proto-sappanins D and E have an excellent potential activity as an alternative to ceftobiprole in limiting MRSA growth through PBP2A enzyme inhibition.

The 2019 novel coronavirus (2019-nCoV) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly from its origin in Wuhan City, Hubei Province, China, to the rest of the world. The efficacy of herbal treatment in the control of contagious disease was demonstrated during the 2003 outbreak of severe acute respiratory syndrome (SARS). Natural compound used for this study were isoflavone and myricetin. Molecular docking was performed to analyze binding mode of the compounds towards 12 proteins related to COVID-19. The prediction shows that isoflavone and myricetin have moderate probability of antiviral activity. All of the docked compounds occupied the active sites of the proteins related to COVID-19. Based on QSAR and molecular docking, interactions were predicted with 10 out of 12 potential COVID-19 proteins for myricetin and with 9 out of 12 proteins interactions for isoflavone. A potential disease alleviating action is suggested for isoflavone and myricetin in the context of COVID-19 infection.

Long Time

Prostaglandins (PGs) with cytoprotective activity were studied for a long time, and a few PGE1 and PGE2 stable analogues were promoted as drugs: arbaprostil, enprostil, misoprostol, and rioptostol. Similarly, nocloprost, a 9β-chlorine prostaglandin analogue, and many 9β- and 11β-substituted prostaglandins were synthesized and studied for their biological activity. We previously synthesized new 9β-halogenated prostaglandins with an ester group at the carbon atom 6 (PGs numbering) by the reaction of a δ-lactone intermediate with diols in acid catalysis. These compounds were used in the current molecular docking study to determine their potential cytoprotective (anti-ulcer) activity. The current study was done with the CLC Drug Discovery Workbench 2.4. software and an oxidoreductase enzyme receptor, chosen from the Protein Data Bank, ID: 4KEW (www.rcsb.org). We used two recognized drugs, omeprazole (co-crystallized with the enzyme) and nocloprost, as the standard. The 9β-halogenated prostaglandin analogs were docked. Nocloprost and all 9β-halogenated compounds had docking scores greater than that of omeprazole. The majority of the 9β-halogenated analogs had docking scores even greater than that of nocloprost, indicating that these compounds could have potential cytoprotective (anti-ulcer) activity. A few correlations between docking score and substituents on the prostaglandin skeleton were found.

Main Protease

A novel (COVID-19) responsible of acute respiratory infection closely related to SARS-CoV has recently emerged. So far there is no consensus for drug treatment to stop the spread of the virus. Discovery of a drug that would limit the virus expansion is one of the biggest challenges faced by the humanity in the last decades. In this perspective, testing existing drugs as inhibitors of the main COVID-19 protease is a good approach.Among natural phenolic compounds found in plants, fruit, and vegetables; flavonoids are the most abundant. Flavonoids, especially in their glycosylated forms, display a number of physiological activities, which makes them interesting to investigate as antiviral molecules.The flavonoids chemical structures were downloaded from PubChem and protease structure 6lu7 was from the Protein Data Bank site. Molecular docking study was performed using AutoDock Vina. Among the tested molecules Quercetin-3-O-rhamnoside showed the highest binding affinity (-9,7 kcal/mol). Docking studies showed that glycosylated flavonoids are good inhibitors for the covid-19 protease and could be further investigated by in vitro and in vivo experiments for further validation.

Objective: The present study aimed to evaluate those 3 compounds among 122 Thai natural products by using a molecular docking approach to inhibit Main Protease (Mpro) of SARS-CoV-2 (PDB code: 6Y2F), Angiotensin Converting Enzyme (ACE)-2 (PDB code: 1R4L), and PAK-1 kinase (PDB code: 5DEW). Methods: The evaluation was performed on the docking scores calculated using AutoDock Vina as a docking engine and interaction profile analysis through 2-dimensional visualization using LigPlot+. The determination of the docking score was done by selecting the conformation of the ligand that has the lowest binding free energy (best pose). Result: The results of this study indicate that overall, Panduratin A has the best affinity in inhibiting the main protease of SARS-CoV-2, ACE-2, and PAK-1 compared to other compounds. Conclusion: The three thai medicinal plants compound has the potential to be developed as specific therapeutic agents against COVID-19.
