The significant immune escape of pseudotyped SARS-CoV-2 variant Omicron
The emergence of Omicron/BA.1 has brought new challenges to fight against SARS-CoV-2. A large number of mutations in the Spike protein suggest that its susceptibility to immune protection elicited by the existing COVID-19 infection and vaccines may be altered.

Ozone gas applied through nebulization as adjuvant treatment for lung respiratory diseases due to COVID-19 infections: a prospective randomized trial
The objective of this study was to provide lung disinfection by nebulizing ozone gas with distilled water and olive oil for patients who have clinical symptoms due to coronavirus disease 2019 (COVID-19) 30 patients who met the study criteria were prospectively evaluated. A statistically significant difference was found in the length of stay in hospital, change in C-reactive protein, polymerase chain reaction results after 5 days, and computed tomography scores between two groups.

Structure-property relationship in thioxotriaza-spiro derivative: Crystal structure and molecular docking analysis against SARS-CoV-2 main protease
Structure and non-covalent interactions in thioxotriaza-spiroderivative (DZ2) are investigated by single crystal structure anslysis and computational approaches. The binding affinity of -6.7kcal/mol is observed, attributed to hydrogen bonding and hydrophobic interactions between the ligand and amino acid residues of the receptor.

Design and synthesis of heterocyclic azole based bioactive compounds: Molecular structures, quantum simulation, and mechanistic studies through docking as multi-target inhibitors of SARS-CoV-2 and cytotoxicity
Two heterocyclic azole compounds were well characterized by analytical and spectroscopic tools. The binding efficiency of the compounds with the molecular targets was comparable with that of remdesivir (SARS-CoV-2), chloroquine and hydroxychloroquine. SVS1, SVS2 and cisplatin were assessed for their cytotoxicity against a panel of three human cancer cells such as HepG-2 (hepatic carcinoma), T24 (bladder) and EA.hy926 (endothelial) cells using MTT assay.

A possible potential COVID-19 drug candidate: Diethyl 2-(2-(2-(3-methyl-2-oxoquinoxalin-1(2H)-yl)acetyl)hydrazono)malonate: Docking of disordered independent molecules of a novel crystal structure, HSA/DFT/XRD and cytotoxicity
Study reports the synthesis, characterization and importance of a novel diethyl 2-(2-methyl-2-oxoquinoxalin-1(2H)-yl)acetyl)hydrazono)malonate. MQOAHM was characterized by means of various spectroscopic tools ESI-MS, IR, (1)H &(13)C NMR analyses. The high binding score of the molecule was attributed to the multi-hydrogen bond and hydrophobic interactions between the ligand and the receptor's active amino acid residues.

MicroRNAs based regulation of cytokine regulating immune expressed genes and their transcription factors in COVID-19
Coronavirus disease 2019 is characterized by the elevation of a broad spectrum of inflammatory mediators associated with poor disease outcomes. We aimed at an in-silico analysis of regulatory microRNA and their transcription factors for these inflammatory genes that may help to devise potential therapeutic strategies in the future.

Computational screening and biochemical analysis of Pistacia integerrima and Pandanus odorifer plants to find effective inhibitors against Receptor-Binding domain (RBD) of the spike protein of SARS-Cov-2
The mortality rate from COVID-19 remains high due to the fourth or fifth wave and the delta variant of the coronavirus. An effective mechanistic investigation in treating this disease is urgently needed. Three phytochemicals, 28-demethyl-beta-amyrone, 24-Noroleana-3,12-diene, and stigmasterol, displayed binding free energy values of-8.3, -7.5 Kcal/mol, respectively, in complexes with the spike protein of SARS-CoV-2.

Yeast-expressed recombinant SARS-CoV-2 receptor binding domain RBD203-N1 as a COVID-19 protein vaccine candidate
SARS-CoV-2 protein subunit vaccines are currently being evaluated by multiple manufacturers to address the global vaccine equity gap, and need for low-cost, easy to scale, safe, and effective COVID-19 vaccines. In this paper, we report on the generation of the RBD203-N1 yeast expression construct, which produces a recombinant protein capable of eliciting a robust immune response and protection in mice against infections.

Molecular docking and dynamic simulations of Cefixime, Etoposide and Nebrodenside A against the pathogenic proteins of SARS-CoV-2
Millions of people were infected and several hundred thousand died of the COVID-19 pandemic across the world. There is no clear targeted drug therapy available for the treatment of the patients. An instantly qualifying approach is needed to utilize the current drugs and isolated compounds. Promising results were obtained via complimentary analysis of molecular dynamics (MD) simulations performed for the complexes of three proteins with etoposide drug.

Tracking the amino acid changes of spike proteins across diverse host species of severe acute respiratory syndrome coronavirus 2
SPIKES identified 20 informative physicochemical properties of the spike protein, including information measures for alpha helix and relative mutability, and amino acid and dipeptide compositions. We suggest that alterations of these amino acids between human and animal coronaviruses may provide insights into the development and transmission of SARS-CoV-2 in human and other species.

Synthesis and evaluation of enantiomers of hydroxychloroquine against SARS-CoV-2 in vitro
There is an urgent need for effective and low-toxic antiviral drugs to remedy Remdesivir's limitation. Hydroxychloroquine, a broad spectrum anti-viral drug, showed inhibitory activity against SARS-CoV-2 in some studies. We adopted a drug repurposing strategy and further investigated hydroxy chloroquine.

Elevation in sphingolipid upon SARS-CoV-2 infection: possible implications for COVID-19 pathology
SARS-CoV-2 infection induced elevation of SL levels in both cells and sera of infected mice. This elevation could be reversed by treatment with glucosylceramide synthase inhibitors. Levels of sphinganine, sphingosine, GA1, and GM3 were significantly increased in both cell and the murine model.

Potential therapeutic effect of glucagon-like peptide-1 receptor agonists on COVID-19-induced pulmonary arterial hypertension
" SARS-CoV-2 often causes a ""cytokine storm"" in people with COVID-19, causing inflammatory lung damage and pneumonia, which eventually leads to death. Glucagon like peptide-1 (GLP-1) is well known as an incretin hormone responsible for regulation of blood glucose through its receptor."

Molecular docking and dynamics studies on propolis sulabiroin-A as a potential inhibitor of SARS-CoV-2
Sulabiroin-A can be used as an alternative inhibitor if a new structure of receptor SARS-CoV-2 is used. The molecular dynamics simulation showed that all the ligands are good candidates as inhibitors. There is still a good possibility that sulabiroins could be used in place of quercetin, remdesivir and other ligands.

Use of Micro-Computed Tomography to Visualize and Quantify COVID-19 Vaccine Efficiency in Free-Breathing Hamsters
The SARS-CoV-2 pandemic has impacted the health of humanity after the outbreak in Hubei, China in late December 2019. Recently, a robust Syrian golden hamster model recapitulating COVID-19 was developed in search for effective therapeutics and vaccine candidates. However, overt clinical disease symptoms were largely absent despite high levels of virus replication and associated pathology in the respiratory tract. Therefore, we used micro-computed tomography (CT) to longitudinally visualize lung pathology and to preclinically assess candidate vaccines.

Molecular Docking and Dynamics Investigations for Identifying Potential Inhibitors of the 3-Chymotrypsin-like Protease of SARS-CoV-2: Repurposing of Approved Pyrimidonic Pharmaceuticals for COVID-19 Treatment
42 pyrimidonic pharmaceuticals (PPs) inhibitory effect of 42 PPs on the 3-chymotrypsin-like protease of SARS-CoV-2. 11 drugs approved by the US Food and Drug Administration showed an excellent binding affinity to the catalytic residues of 3CL(pro) of His41 and Cys145. Citicoline and uridine triacetate showed free binding energies of -25.53 and -7.07 kcal/mol, respectively. Therefore, I recommend that they be repurposed for the fight against COVID-19, following proper experimental and clinical validation.

Persimmon-derived tannin has antiviral effects and reduces the severity of infection and transmission of SARS-CoV-2 in a Syrian hamster model
Persimmon-derived tannin suppressed SARS-CoV-2 titers measured by plaque assay in vitro in a dose- and time-dependent manner. Inactivating the virus in saliva and the oral cavity represents a reasonable approach to prevent human-to-human transmission because the virus is easily transmitted through oral routes by dispersed saliva.
