The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a potentially lethal infection that presents substantial threat to health, especially in nations. Given no FDA-approved specific therapy for MERS exists, designing and discovering potent antiviral MERS-CoV crucial. One pivotal strategy inhibiting replication focus on the viral main protease (Mpro). In this study, we identify potential novel Mpro inhibitors employing structure-based virtual screening of our recently reported Ugi reaction-derived library (URDL) consisting cherry-picked molecules from literature. key features URDL include synthetic tractability (1-2 pot synthesis) scaffold unexplored chemical space. hits were ranked based docking score, MM-GBSA free energy binding, interaction pattern with active site residues. A molecular dynamics (MD) simulation study was performed first two top-ranked compounds analyze stability binding mechanics Poisson-Boltzmann surface area. mean force calculated steered (SMD) simulations indicates improved H-bond potential, enhanced conformational stability, affinity toward target, compared cocrystallized ligand. discovered represent synthetically tractable scaffolds as inhibitors.Communicated by Ramaswamy H.

Ensitrelvir is a noncovalent inhibitor of the main protease (Mpro) severe acute respiratory syndrome coronavirus 2. Acquisition drug resistance in virus-derived proteins serious therapeutic concern, and occurs due to amino acid mutations. In this study, we computationally constructed 24 mutants, which one residue around active site was replaced with alanine performed molecular dynamics simulations complex Mpro ensitrelvir predict residues involved resistance. We evaluated changes entire protein structure ligand configuration each these mutants estimated were recognition. This method called virtual scan. nine (S1A, T26A, H41A, M49A, L141A, H163A, E166A, V186A, R188A), although catalytic dyad (cysteine (Cys)145 histidine (His)41) not significantly moved, changed.

During the continuing evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Omicron variant concern emerged in second half 2021 and has been dominant since November that year. Along with its sublineages, it maintained a prominent role ever since. The Nsp5 main protease (Mpro) virus is characterized by single mutation, P132H. Here we determined X-ray crystal structures P132H mutant (or O-Mpro) as free enzyme complex Mpro inhibitor, alpha-ketoamide 13b-K, conducted enzymological, biophysical well theoretical studies to characterize O-Mpro. We found O-Mpro similar overall structure binding 13b-K; however, displays lower enzymatic activity thermal stability compared WT-Mpro (with "WT" referring prototype strain). Intriguingly, imidazole ring His132 carboxylate plane Glu240 are stacked configuration here. Empirical folding energy calculations suggest dimer destabilized relative due less favorable van der Waals interactions backbone conformations individual protomers. All-atom continuous constant-pH molecular dynamics (MD) simulations reveal display coupled titration. At pH 7, predominantly neutral respect which charged. In order examine whether mutation eases emergence further mutations, also analyzed P132H+T169S double mutant, characteristic BA.1.1.2 lineage. However, little evidence correlation between two sites.
