• SARS-CoV-2 receptor binding domain by molecular docking” [6]. This research work showcases peptides that are capable to bind and neutralize the SARS-CoV-2 virus through molecular docking. The latest developments of the molecular docking of peptides by molecular dynamics were investigated to understand

• peptides to neutralize the infective mechanism of SARS-CoV-2 through the RBD is an interesting strategy. The binding ability of 104 peptides (University of Nebraska Medical Center’s Antimicrobial Peptide Database) to the RBD was assessed using molecular docking. Based on the molecular docking results

• variants of SARS-CoV-2. This research work will be focused on the molecular docking of peptides by molecular dynamics, in addition to an analysis of the possible interaction of these peptides with physiological proteins. This methodology could be extended to design peptides that are active against other

• viruses. Keywords: angiotensin converting enzyme-2 (ACE2); antiviral peptides; hydrogen bonds; molecular docking; SARS-CoV-2 RBD; Introduction The current pandemic due to coronavirus disease-19 (COVID-19), caused by the novel virus SARS-CoV-2, has over 533 million of confirmed cases and over 6.3 million

• the trajectories. Molecular docking Blind docking calculations were performed using AutoDock 4.2 [47] software. The 3D structure of the drug (Figure 6A), was sketched and preoptimized; partial charges were assigned and rotatable bonds were identified. All files for docking calculations were prepared

• stabilizing the InhA–isoconazole complex. To assess these interactions, frontier molecular orbital calculations were performed for the active site of InhA and isoconazole obtained from docking. Isoconazole was predicted to be an active inhibitor of InhA with the analysis of the molecular docking and electron

• density distribution. It has been detected that alginate–chitosan–cyclodextrin microparticulate systems loaded with INH and ISN are as effective as pure INH applied in higher dosages. Keywords: chitosan; β-cyclodextrin; density functional theory (DFT); isoconazole; isoniazid; molecular docking

• compound of 5–10 μg/mL and with pure INH at a concentration of 100 μg/mL in the treatment medium. We have suggested that the antimycobacterial activity of ISN is the result of its inhibitory action against the enzyme InhA. To confirm our suggestion, we carried out a molecular docking analysis of the
