ABSTRACT
Background: The deadly virus COVID-19 has affected more than 1 crore people and claimed more than 5 lakh lives worldwide according to the World health organization. Though there are numerous treatment modalities available including anti-bacterials, antivirals, vaccines etc., none of them can be considered as effective cure for SARS CoV-2 virus as they are mostly non-specific in action. Aim(s): siRNA therapy can be considered as a significant treatment modality due to its specificity in action. The aim of this review is to explore siRNA as a potential treatment strategy for the treatment of COVID-19. Material(s) and Method(s): In this review we shall explore the targets of siRNA therapy which includes viral RNA-dependent RNA polymerase, helicase, protease and nucleoprotein N. siRNA related patents provide solutions for novel RNAi techniques, high expense of chemically synthetic siRNA, techniques for restraining SARS-CoV by disturbing RNA etc., siRNA-based drug delivery systems and limitations of nanocarrier delivery system were reviewed. siRNA is a gene silencer that targets highly conserved sequences which codes for protease 3CL (nsp5) and viral helicase (from 16-18 kbp). Conclusion(s): Thus, siRNA-based therapy is considered highly efficacious as it can hit the highly conserved regions of SARS-CoV-2 RNA.Copyright © 2023, Advanced Scientific Research.
