ALKBH5 inhibitors can reduce the replication of SARS-CoV-2 through an interaction with host cells, potentially providing a new strategy for antiviral treatment. This finding paves the way for the development of molecules that are less susceptible to drug resistance.
Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a positive-sense, single stranded RNA virus, responsible for the pandemic outbreak called COVID-19. The pandemic, still ongoing, had presented unprecedented challenges in terms of finding appropriate pharmacological treatments. Methods Starting from the recent literature that demonstrates how ALKBH5 inhibitors could be used as a new strategy to reduce SARS-CoV-2 replication, we decided to repurpose our newly discovered ALKBH5 inhibitor MV1035, previously tested and proved effective against glioblastoma, for its putative antiviral activity against SARS-CoV-2. We demonstrated a reduction in SARS-CoV-2-induced CPE after 72 h incubation using MV1035 (50 & mu;M), for SARS-CoV-2 wild type (Wuhan strain) and South African variant. Results The results show how MV1035 seems to be able to reduce SARS-CoV-2 replication through an indirect mechanism of action, which might involve an interaction with the host cell rather than with a virus protein. Conclusion This may be particularly interesting as it lays the foundation for the rational design of molecules in principle not subject to drug resistance, as host cell proteins are not affected by virus mutations.
