Abstract

The coronavirus disease 2019 (COVID-19) is a contagious disease that is caused by a novel coronavirus. The human coronavirus (HCoV) is recognized as one of the most rapidly evolving viruses owing to its high genomic nucleotide substitution rates and recombination. Among the severe acute respiratory syndrome (SARS) and Middle- East respiratory syndrome (MERS), COVID-19 has spread more rapidly and increased the level of globalization and adaptation of the virus in every environmental condition due to their high rate of molecular diversity. The whole article highlights the general characteristics of coronavirus, their molecular diversity, and molecular protein targeting against COVID-19 with their newer approaches. Through this review, an attempt has been made to critically evaluate the recent advances and future aspects that are helpful to the treatment of COVID-19 based on the present understanding of SARS-CoV-2 infections, which may offer new insights and potential therapeutic targets for the treatment of COVID-19.

Keywords: COVID-19, molecular targeting, molecular diversity, SARS-CoV-2, clinical trials, future prospective.
