The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused an unprecedented global public health crisis and continues to pose grave threats to human health. The efficacy of current vaccines and therapeutics is likely limited for future emerging strains due to the highly mutative nature of the virus, underscoring an urgent need for the development of new, potent antiviral agents. In this study, we report the design and synthesis of a series of novel 2′-deoxy-2′-spirooxetane-7-deazapurine nucleoside analogs as potential inhibitors of SARS-CoV-2 replication. Some of these compounds demonstrate potent antiviral activity, offering a potential new weapon for therapeutic intervention against the ever-evolving SARS-CoV-2 virus. Among the tested compounds, nucleoside analog 11q exhibited the most potent antiviral activity against SARS-CoV-2 in Vero E6 cells, with IC values of 0. 14 μM for the wild-type strain and 0. 36 μM for the BA. 5 strain. Notably, compound 11q exhibits up to nine times greater inhibitory activity against wild-type SARS-CoV-2 compared to Remdesivir and also possesses a superior selectivity index. These findings suggest that compound 11q is a highly promising lead candidate for future drug development aimed at combating SARS-CoV-2.
