Combinatorial therapeutic trial plans for COVID-19 treatment armed up with antiviral, antiparasitic, cell-entry inhibitor, and immune-boosters.

ABSTRACT: SARS-CoV-2, or novel coronavirus, is causing the fatal and contagious coronavirus disease-2019 (COVID-19) affecting thousands of people every single day. Researchers are continuously searching for any possible cure and/or vaccine, but no conclusive report is available till date. Like many others, we realize that a rapid, immediate, and elaborate strategy must be adopted to protect mankind. To avoid the time-loss due to clinical trials, we have performed in silico analyses on some FDA-approved drugs to combat COVID-19. We accessed information from public databases and publications, and studied the mechanism of infection of SARS-CoV-2 and the interactions of various drugs with SARS-CoV-2 proteins in silico. We found a few antivirals and antiparasitic drugs to show significant interactions with important SARS-CoV-2 proteins. Particularly Galidesivir, Remdesivir, and Pirodavir have been chosen as suggested antiviral drugs; and Proguanil, Mefloquine, and Artesunate have been chosen as suggested antiparasitic drugs based on such predicted interactions. In addition, inhibitors to prevent host-cell entry and a few supportive immune-boosters can be used in different combinations. Our study proposes a four-way attack to this fatal virus for the possible management of COVID-19 armed up with an antiviral, an antiparasitic drug, a cell-entry inhibitor, and a few supportive immune-boosters, which can be used in different combinations in different groups of people.

Project description:Numerous peptides inhibit the entry of enveloped viruses into cells. Some of these peptides have been shown to inhibit multiple unrelated viruses. We have suggested that such broad-spectrum antiviral peptides share a property called interfacial activity; they are somewhat hydrophobic and amphipathic, with a propensity to interact with the interfacial zones of lipid bilayer membranes. In this study, we further tested the hypothesis that such interfacial activity is a correlate of broad-spectrum antiviral activity. In this study, several families of peptides, selected for the ability to partition into and disrupt membrane integrity but with no known antiviral activity, were tested for the ability to inhibit multiple diverse enveloped viruses. These include Lassa pseudovirus, influenza virus, dengue virus type 2, herpes simplex virus 1, and nonenveloped human adenovirus 5. Various families of interfacially active peptides caused potent inhibition of all enveloped viruses tested at low and submicromolar concentrations, well below the range in which they are toxic to mammalian cells. These membrane-active peptides block uptake and fusion with the host cell by rapidly and directly interacting with virions, destabilizing the viral envelope, and driving virus aggregation and/or intervirion envelope fusion. We speculate that the molecular characteristics shared by these peptides can be exploited to enable the design, optimization, or molecular evolution of novel broad-spectrum antiviral therapeutics.IMPORTANCE New classes of antiviral drugs are needed to treat the ever-changing viral disease landscape. Current antiviral drugs treat only a small number of viral diseases, leaving many patients with established or emerging infections to be treated solely with supportive care. Recent antiviral peptide research has produced numerous membrane-interacting peptides that inhibit diverse enveloped viruses in vitro and in vivo Peptide therapeutics are becoming more common, with over 60 FDA-approved peptides for clinical use. Included in this class of therapeutics is enfuvirtide, a 36-residue peptide drug that inhibits HIV entry/fusion. Due to their broad-spectrum mechanism of action and enormous potential sequence diversity, peptides that inhibit virus entry could potentially fulfill the need for new antiviral therapeutics; however, a better understanding of their mechanism is needed for the optimization or evolution of sequence design to combat the wide landscape of viral disease.
