Since Dec. 2019, humanity has faced an important global threat. Many studies have been published on the origin, structure, and mechanism of action of the SARS-CoV-2 virus and the treatment of its disease. The priority of scientists all over the world has been to direct their time to research this subject. In this review, we highlight chem. studies and therapeutic approaches to overcome COVID-19 with seven different sections. These sections are the structure and mechanism of action of SARS-CoV-2, immunotherapy and vaccine, computer-aided drug design, repurposing therapeutics for COVID-19, synthesis of new mol. structures against COVID-19, food safety/security and functional food components, and potential natural products against COVID-19. In this work, we aimed to screen all the newly synthesized compounds, repurposing chems. covering antiviral, anti-inflammatory, antibacterial, antiparasitic, anticancer, antipsychotic, and antihistamine compounds against COVID-19. We also highlight computer-aided approaches to develop an anti-COVID-19 mol. We explain that some phytochems. and dietary supplements have been identified as antiviral bioproducts, which have almost been successfully tested against COVID-19. In addition, we present immunotherapy types, targets, immunotherapy and inflammation/mutations of the virus, immune response, and vaccine issues.

Zhao, Mengmeng published the artcileRecent progress of antiviral therapy for coronavirus disease 2019, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is review COVID19 antiviral therapy; Antiviral therapy; COVID-19; SARS-CoV-2.

The coronavirus disease 2019 (COVID-19) pandemic has become a global public health crisis, for which antiviral treatments are considered mainstream therapeutic approaches. With the development of this pandemic, the number of clin. studies on antiviral therapy, including remdesivir, chloroquine and hydroxychloroquine, lopinavir/ritonavir, ribavirin, arbidol, interferon, favipiravir, oseltamivir, nitazoxanide, nelfinavir, and camostat mesylate, has been increasing. However, the efficacy of these antiviral drugs for COVID-19 remains controversial. In this review, we summarize the recent progress and findings on antiviral therapies, aiming to provide clin. support for the management of COVID-19. In addition, we analyze the causes of controversy in antiviral drug research and discuss the quality of current studies on antiviral treatments. High-quality randomized clin. trials are required to demonstrate the efficacy and safety of antiviral drugs for the treatment of COVID-19.

Guedes, Isabella A. published the artcileDrug design and repurposing with DockThor-VS web server focusing on SARS-CoV-2 therapeutic targets and their non-synonym variants, Name: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is SARSCOV2 therapeutic target drug design repurposing.

The COVID-19 caused by the SARS-CoV-2 virus was declared a pandemic disease in March 2020 by the World Health Organization (WHO). Structure-Based Drug Design strategies based on docking methodologies have been widely used for both new drug development and drug repurposing to find effective treatments against this disease. In this work, we present the developments implemented in the DockThor-VS web server to provide a virtual screening (VS) platform with curated structures of potential therapeutic targets from SARS-CoV-2 incorporating genetic information regarding relevant non-synonymous variations. The web server facilitates repurposing VS experiments providing curated libraries of currently available drugs on the market. At present, DockThor-V S provides ready-for-docking 3D structures for wild type and selected mutations for Nsp3 (papain-like, PLpro domain), Nsp5 (Mpro, 3CLpro), Nsp12 (RdRp), Nsp15 (NendoU), N protein, and Spike. We performed VS experiments of FDA-approved drugs considering the therapeutic targets available at the web server to assess the impact of considering different structures and mutations to identify possible new treatments of SARS-CoV-2 infections. The DockThor-VS is freely available at www.dockthor.lncc.br.

Ajima, Ukpe published the artcileA review of the structure-activity relationships (SAR) of selected drugs with potential to be repurposed against SARS-COV-2, Formula: C12H9N3O5S, the main research area is review SARSCoV2 antiviral drug repurposing structure activity relationship.

Background: The pandemic caused by the novel SARS-CoV-2 virus has escalated rapidly and impacted human health worldwide, in addition to causing severe disruptions to socioeconomic life. There is presently no effective treatment for the disease and this underscores the urgent need for new therapeutic options against this life threatening disease. The traditional strategy for the development of new drugs is a slow and expensive process. Drug repurposing is a valuable alternative strategy that can be used to bypass some of the limitations of traditional drug discovery in order to rapidly develop new therapeutic agents for the management of Covid-19. Objectives: The present review x-rays recent efforts to re-purpose some antiviral drugs for the treatment of SARS-Cov-2 with an emphasis on the structure activity relationships (SAR) of the compounds Methods: A systematic internet search of three academic databases of published literature was undertaken using relevant keywords and search terms which focused on drug re-purposing against SARS-CoV-2. Results: A total of 853 results were generated and evaluated. The results of the search were screened and relevant articles identified, yielding a total of 83 articles. Some of the drugs identified with potential for re-purposing against SARS-CoV-2 include: Arbidol, Favipiravir, Ribavirin, Nitazoxanide etc. Conclusion: It is hoped that the information generated in this review will help deepen understanding of the potential mechanism of anti-SARS-CoV-2 action of the compounds and also draw attention to opportunities that exist for structural modification of these mols. with the aim of improving and enhancing their selectivity and efficacy against SARS-CoV-2.

Kern, Charlotte published the artcileModeling of SARS-CoV-2 treatment effects for informed drug repurposing, Synthetic Route of 55981-09-4, the main research area is disease modeling SARSCoV2 treatment drug repurposing COVID19 pharmacometric; COVID-19; disease modeling; drug repurposing; pharmacometrics; viral kinetics.

Several repurposed drugs are currently under investigation in the fight against coronavirus disease 2019 (COVID-19). Candidates are often selected solely by their effective concentrations in vitro, an approach that has largely not lived up to expectations in COVID-19. Cell lines used in in vitro experiments are not necessarily representative of lung tissue. Yet, even if the proposed mode of action is indeed true, viral dynamics in vivo, host response, and concentration-time profiles must also be considered. Here we address the latter issue and describe a model of human SARS-CoV-2 viral kinetics with acquired immune response to investigate the dynamic impact of timing and dosing regimens of hydroxychloroquine, lopinavir/ritonavir, ivermectin, artemisinin, and nitazoxanide. We observed greatest benefits when treatments were given immediately at the time of diagnosis. Even interventions with minor antiviral effect may reduce host exposure if timed correctly. Ivermectin seems to be at least partially effective: given on positivity, peak viral load dropped by 0.3-0.6 log units and exposure by 8.8-22.3%. The other drugs had little to no appreciable effect. Given how well previous clin. trial results for hydroxychloroquine and lopinavir/ritonavir are explained by the models presented here, similar strategies should be considered in future drug candidate prioritization efforts.

Bobrowski, Tesia published the artcileSynergistic and Antagonistic Drug Combinations against SARS-CoV-2, Safety of 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is synergistic antagonistic drug combination SARS CoV 2; COVID-19; CPE assay; SARS-CoV-2; combination therapy; drug combinations; drug repurposing; drug synergy; in silico design; knowledge mining; nitazoxanide remdesivir combo.

Antiviral drug development for coronavirus disease 2019 (COVID-19) is occurring at an unprecedented pace, yet there are still limited therapeutic options for treating this disease. We hypothesized that combining drugs with independent mechanisms of action could result in synergy against SARS-CoV-2, thus generating better antiviral efficacy. Using in silico approaches, we prioritized 73 combinations of 32 drugs with potential activity against SARS-CoV-2 and then tested them in vitro. Sixteen synergistic and eight antagonistic combinations were identified; among 16 synergistic cases, combinations of the US Food and Drug Administration (FDA)-approved drug nitazoxanide with remdesivir, amodiaquine, or umifenovir were most notable, all exhibiting significant synergy against SARS-CoV-2 in a cell model. However, the combination of remdesivir and lysosomotropic drugs, such as hydroxychloroquine, demonstrated strong antagonism. Overall, these results highlight the utility of drug repurposing and preclin. testing of drug combinations for discovering potential therapies to treat COVID-19.

Khatri, Manisha published the artcileNitazoxanide/Camostat combination for coronavirus disease 2019 (COVID-19): an unexplored potential therapy, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is coronavirus disease 2019 nitazoxanide camostat.

Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lies behind the ongoing outbreak of coronavirus disease 2019 (COVID-19) and its ripple effects has brought major challenges to worldwide health systems. Urgent strategies are required to manage this pandemic and repurposing of existing drugs offer an option forward. A combination drug therapy for COVID-19 aims to prevent both the virus entry/spread as well as quelling the immune system havocs that the virus wreaks in the human body. This article analyzes Nitazoxanide/Camostat combination for their potential activity against SARS-CoV-2. Nitazoxanide, FDA approved drug potentiates host antiviral response, thereby reducing viral replication, titer and ensuing immune dysregulation. Camostat, a potent serine protease inhibitor locks viral cell entry along with the potential to decrease COVID-19-associated hypercoagulability. Both the drugs do not inhibit CYP 450 enzymes and could be co-administered. Based on the combined pathophysiol. and pharmacol. potential, the drugs combination can prospectively be recommended for early evaluation with possible clin. trials of this combination.
