Immunoliposomes As a Promising Antiviral Agent against SARS-CoV-2. DOKL BIOCHEM BIOPHYS 2024; 514:6-10. [PMID: 38189883 PMCID: PMC11021331 DOI: 10.1134/s1607672923700618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 10/20/2023] [Accepted: 10/21/2023] [Indexed: 01/09/2024]
Abstract
According to the World Health Organization, as of January 3, 2020 to September 13, 2023, there were approximately 23 million confirmed cases of COVID-19 reported in the Russian Federation, about 400 thousand of which were fatal. Considering the high rate of mutation of the RNA-containing virus genome, which inevitably leads to the emergence of new infectious strains (Eris and Pyrola), the search for medicinal antiviral agents remains an urgent task. Moreover, taking into account the actively mutating receptor-binding domain, this task requires fundamentally new solutions. This study proposes a candidate immunoliposomal drug that targets the S protein of SARS-CoV-2 by the monoclonal neutralizing antibody P4A1 and ensures the penetration of a highly active ribonuclease into the virus-infected cell, which degrades, among cellular RNA, viral RNA too. We demonstrate a more than 40-fold increase in the neutralizing activity of the developed drug compared to the free monoclonal neutralizing antibody.

[PMID: 37054806 PMCID: PMC10085972 DOI: 10.1016/j.nano.2023.102674] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 03/19/2023] [Accepted: 03/28/2023] [Indexed: 04/15/2023]
Abstract
The devastating COVID-19 pandemic motivates the development of safe and effective antivirals to reduce morbidity and mortality associated with infection. We developed nanoscale liposomes that are coated with the cell receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19. Lentiviral particles pseudotyped with the spike protein of SARS-CoV-2 were constructed and used to test the virus neutralization potential of the engineered liposomes. Under TEM, we observed for the first time a dissociation of spike proteins from the pseudovirus surface when the pseudovirus was purified. The liposomes potently inhibit viral entry into host cells by extracting the spike proteins from the pseudovirus surface. As the receptor on the liposome surface can be readily changed to target other viruses, the receptor-coated liposome represents a promising strategy for broad spectrum antiviral development.
