VOC 202012/01 Variant Is Effectively Neutralized by Antibodies Produced by Patients Infected before Its Diffusion in Italy.

ABSTRACT: The coronavirus disease 2019 (Covid-19) pandemic is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and presents a global health emergency that needs urgent intervention. Viruses constantly change through mutation, and new variants of a virus are expected to occur over time. In the United Kingdom (UK), a new variant called B.1.1.7 has emerged with an unusually large number of mutations. The aim of this study is to evaluate the level of protection of sera from 12 patients infected and later healed in Apulia Region (Italy) with Covid-19 between March and November 2020, when the English variant was not circulating in this territory yet, against the new VOC 202012/01 variant by seroneutralization assay. The sera of patients had already been tested before, using a virus belonging to the lineage B.1 and showed an antibody neutralizing titer ranging between 1:160 and 1:320. All the 12 sera donors confirmed the same titers of neutralizing antibodies obtained with a strain belonging to the lineage B.1.1.7 (VOC 202012/01). These data indicate that antibodies produced in subjects infected with variants of Sars-CoV-2 strain before the appearance of the English one, seem to have a neutralizing power also against this variant.

Project description:Polyhydroxyphenols and nitrogenous heterocyclics are two of the most powerful active species of molecules in pharmaceutical chemistry, as each of them is renowned for its various bioactivities for humans. One of their outstanding actions is the antiviral activities, which clearly appear if the principal functional entities of both classes meet into one compound. The recent COVID-19 pandemic pushed us to computationally sift and assess our small library of synthetic 2-(3,4,5-trihydroxyphenyl)-1,3,4-oxadiazoles against the main coronaviral protein/enzymatic targets. Surprisingly, few ligands exhibited interesting low binding energies (strong inhibitory affinities) with some SARS-CoV-2 proteins, mainly the pivotal enzyme RNA-dependent RNA polymerase (nCoV-RdRp). One of these compounds was Taroxaz-104 (5,5'-{5,5'-[(1R,2R)-1,2-dihydroxyethane-1,2-diyl]bis(1,3,4-oxadiazole-5,2-diyl)}dibenzene-1,2,3-triol), which presented lower binding free energies of about -10.60 and -9.10 kcal/mol (as compared to the reference agent, GS-443902, which presented about -9.20 and -7.90 kcal/mol) with nCoV-RdRp-RNA and nCoV-RdRp alone, respectively. Extensive molecular modeling examination disclosed the potent Taroxaz-104 inhibition of one of the possible active/allosteric sites of nCoV-RdRp, since Taroxaz-104 molecule interacts with at least seven main amino acids of the presumed pocket/cavity of this nCoV-RdRp active site. The effective repurposing of Taroxaz-104 molecule was attained after the satisfactorily interesting results of the anti-COVID-19 bioassay were secured, since these data demonstrated that Taroxaz-104 showed very efficient anti-COVID-19 actions (anti-SARS-CoV-2 EC50 = 0.42 μM) with specific promising efficacy against the new SARS-CoV-2 strains. Additional research studies for the progress of Taroxaz-104 and other related polyphenolic 2,5-disubstituted-1,3,4-oxadiazole analogs as successful anti-SARS-CoV-2 medications, via, e.g., preclinical/clinical trials, are pressingly required.

Project description:The high risk of morbidity and mortality associated with SARS-CoV-2 has accelerated the development of many potential vaccines. However, these vaccines are designed against SARS-CoV-2 isolated in Wuhan, China, and thereby may not be effective against other SARS-CoV-2 variants such as the United Kingdom variant (VUI-202012/01). The UK SARS-CoV-2 variant possesses D614G mutation in the Spike protein, which impart it a high rate of infection. Therefore, newer strategies are warranted to design novel vaccines and drug candidates specifically designed against the mutated forms of SARS-CoV-2. One such strategy is to target ACE2 (angiotensin-converting enzyme2)-Spike protein RBD (receptor binding domain) interaction. Here, we generated a homology model of Spike protein RBD of SARS-CoV-2 UK strain and screened a marine seaweed database employing different computational approaches. On the basis of high-throughput virtual screening, standard precision, and extra precision molecular docking, we identified BE011 (Dieckol) as the most potent compounds against RBD. However, Dieckol did not display drug-like properties, and thus different derivatives of it were generated in silico and evaluated for binding potential and drug-like properties. One Dieckol derivative (DK07) displayed good binding affinity for RBD along with acceptable physicochemical, pharmacokinetic, drug-likeness, and ADMET properties. Analysis of the RBD-DK07 interaction suggested the formation of hydrogen bonds, electrostatic interactions, and hydrophobic interactions with key residues mediating the ACE2-RBD interaction. Molecular dynamics simulation confirmed the stability of the RBD-DK07 complex. Free energy calculations suggested the primary role of electrostatic and Van der Waals' interaction in stabilizing the RBD-DK07 complex. Thus, DK07 may be developed as a potential inhibitor of the RBD-ACE2 interaction. However, these results warrant further validation by in vitro and in vivo studies.
