Computational Simulations Identified Marine-Derived Natural Bioactive Compounds as Replication Inhibitors of SARS-CoV-2

Abstract: The rapid spread of COVID-19, caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a worldwide health emergency. Unfortunately, to date, a very small number of remedies have been to be found effective against SARS-CoV-2 infection. Therefore, further research is required to achieve a lasting solution against this deadly disease. Repurposing available drugs and evaluating natural product inhibitors against target proteins of SARS-CoV-2 could be an effective approach to accelerate … Show more

“…Compared with drug repurposing, screenings for hit compounds, either in vitro or in silico , incorporate a much larger scale of molecules including microbial metabolites, natural products and marine-derived bio-active compounds ( Cragg and Newman, 2013 ; Kumar et al, 2021 ; Quimque et al, 2021 ). Since the outbreak of COVID-19, the widespread use of combinatorial screening has revealed a large mount of hit compounds that specifically target SARS-CoV-2 PLpro ( Amin et al, 2021 ; Gogoi et al, 2021 ; Goyzueta-Mamani et al, 2021 ; Hajbabaie et al, 2021 ; Jade et al, 2021 ; Jamalan et al, 2021 ; Kumar et al, 2021 ; Li et al, 2021 ; Quimque et al, 2021 ; Rahul and Sarkar, 2021 ; Rudrapal et al, 2021 ; Stasiulewicz et al, 2021 ). Hits generated through the initial screens are further validated with an aim to choose the best ones to serve as leads for drug developments.…”

“…To reduce the cost and time of the screening process, we first filtered the compound libraries based on their Lipinski’s Ro5 and ADMET properties ( Figure 5 and Table S3 ), as suggested in previous reports [ 43 , 44 ]. Ro5 states that compounds have drug-like characteristics when the AlogP value ≤ 5, while HBD and HBA numbers are ≤5 and 10, respectively.…”

“…To study the real-time dynamics, we employed MD simulation studies. The selected protein–ligand complexes were prepared and subjected to MD simulations [ 43 , 44 , 59 ]. For comparative study, the known inhibitors THZ1 and CT7001 were also simulated.…”

“…Consequently, the compounds acquired were docked with the Hpse model by allowing for generation of 10 conformers per ligand. The obtained conformations were clustered to achieve the largest cluster, from which the compounds were evaluated on the basis of two scoring criterions [ 73 ]—Goldscore (high) and Chemscore (low) [ 74 ]—as well as the molecular interactions with the Hpse catalytic site residues (Asp62, Asn64, Thr97, Glu225, Asn227, Lys231, Gln270, Arg272, Glu343, Gly349, Gly350, Ala388 and Tyr391).…”
