Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a global COVID-19 pandemic that has affected the lives of billions of individuals. However, the host-virus interactions still need further investigation to reveal the underling mechanism of SARS-CoV-2 pathogenesis. Here, transcriptomics analysis of SARS-CoV-2 infection highlighted possible correlation between host-associated signaling pathway and virus. In detail, cAMP-PKA pathway has an essential role in SARS-CoV-2 infection, followed by the interaction between cyclic AMP response element binding protein (CREB) and CREB-binding protein (CBP) could be induced and leading to the enhancement of CREB/CBP transcriptional activity. The replication of Delta and Omicron BA.5 were inhibited by about 49.4% and 44.7% after knockdown of CREB and CBP with siRNAs, respectively. Furthermore, a small organic molecule naphthol AS-E (nAS-E), which targets on the interaction between CREB and CBP, potently inhibited SARS-CoV-2 wild-type (WT) infection with comparable the half-maximal effective concentration (EC[SUB]50[/SUB] ) 1.04 μM to Remdesivir 0.57 μM. Compared with WT virus, EC[SUB]50[/SUB] in Calu-3 cells against Delta, Omicron BA.2 and Omicron BA.5 were, on average, 1.5-fold, 1.1-fold and 1.5-fold higher, respectively, nAS-E had a satisfied antiviral effect against Omicron variants. Taken together, our study demonstrated the importance of CREB/CBP induced by cAMP-PKA pathway during SARS-CoV-2 infection, and further provided a novel CREB/CBP interaction therapeutic drug targets for COVID-19.
