Abstract
Background: In December 2019, a new coronavirus (nCoV) emerged as a public health concern spreading all around the world. Several attempts have been made to discover effective drugs and vaccines. Up to now, multiple COVID-19 vaccines have been developed against this mysterious virus, and a lot of individuals have already got vaccinated.
Objective: Anti-viral drugs are effective in treating and managing COVID-19. Nucleoside reverse transcriptase inhibitors (NRTIs) are a collection of antiviral drugs for treating HIV and HBV infections. These drugs prevent virus replication by blocking reverse transcriptase (RT). In this review, we discuss the interaction of this class of anti- HIV drugs with specific functional proteins and enzymes of SARSCoV- 2.
Methods: A search of the databases, including Web of Science, Embase, PubMed, Scopus, and Google Scholar, was conducted from commencement to September 2020. The relevant articles on the potential effects of NRTIs on COVID-19 were collected. Finally, twenty-three articles were selected, including all in vitro, in vivo, and clinical studies.
Results: It was observed that RdRp, spike, ACE2, PNP, inflammatory cytokines, and nucleocapsid protein participate in the pathogenesis of SARS-CoV-2. NRTIs target these proteins by binding to them.
Conclusion: This review is focused on the mechanisms of NRTIs to introduce them as potential therapies for COVID-19. However, further in vitro and in vivo investigations will provide helpful information for the identification of drug candidates as a part of COVID-19 management.
Keywords: Coronavirus, SARS-CoV-2, COVID-19, RdRp, nucleoside reverse transcriptase inhibitors, zidovudine.
