Abstract
Background: SARS-CoV and SARS-CoV-2 are exceedingly contagious and typically result in major respiratory illnesses (acute respiratory syndrome). The public health is facing enormous challenges across all the nations due to these newly emerging pathogens. Reliable and systematic examination of SARS-CoV and COVID-19 will assist in identifying infectious persons accurately. Based on the biological, chemical, and genetic link of SARS CoV-2 towards SARS-CoV, the recurrence of different anti-SARS-CoV natural drug molecules may be beneficial in the advancement of anti-COVID-19 herbal drug molecules. Here in this review, we evaluated SAR research that has recently been published as well as molecular docking analysis of previously synthesised compounds that have been targeted against SARS-CoV and SARS-CoV-2, respectively. This investigation might assist scientists in creating novel and revolutionary molecules that could target SAR-CoV-2.
Objectives: The review highlights the heterocyclic inhibitors' ability to successfully inhibit SARSCoV and SARS-CoV-2. The meticulously described structure-activity relationship of potential SARS-CoV and SARS-CoV-2 inhibiting compounds has been addressed in this review.
Evidence Acquisition: We conducted a thorough literature assessment employing electronic databases for scientific articles highlighting potential heterocyclic inhibitors for SARS-CoVand SARSCoV- 2, published from 2010 to 2021. We recovered 415 articles, but only 220 were involved and conversed in this manuscript. The article apprehended appropriate research considering three areas: 1) SAR activity, 2) Molecular docking, and 3) Biological activity and future prospects on SARS-CoV-2.
Methods: The potential compounds with decent inhibitory activity have been discussed and reviewed along with their inhibition potential, expressed in terms of IC50 value.
Results: Heterocyclic scaffolds reflect an extensive spectrum of therapeutic activity and might function as an initiating concept for the designing and discovery of potential inhibitors for SARS-CoV and SARS-CoV-2 treatment.
Conclusion: The points highlighted here may prove to be a vital tool for medicinal chemists working/ investigating more potent and efficacious scaffolds in treating SARS-CoV and SARS-CoV-2.
Keywords: SARS-CoV, SARS-CoV-2, biological activity, structure-activity relationship, molecular docking
